Art History on Wikipedia, a Macroscopic Observation	Doron Goldfarb Max Arends Josef Froschauer Dieter Merkl		ArXiv	English	20 April 2013	How are articles about art historical actors interlinked within Wikipedia? Lead by this question, we seek an overview on the link structure of a domain specific subset of Wikipedia articles. We use an established domain-specific person name authority, the Getty Union List of Artist Names (ULAN), in order to externally identify relevant actors. Besides containing consistent biographical person data, this database also provides associative relationships between its person records, serving as a reference link structure for comparison. As a first step, we use mappings between the ULAN and English Dbpedia provided by the Virtual Internet Authority File (VIAF). This way, we are able to identify 18,002 relevant person articles. Examining the link structure between these resources reveals interesting insight about the high level structure of art historical knowledge as it is represented on Wikipedia.	0	1
A Malicious Bot Capturing System using a Beneficial Bot and Wiki	Takashi Yamanoue Kentaro Oda Koichi Shimozono	Information security Network analysis	Journal of Information Processing	English	February 2013	Locating malicious bots in a large network is problematic because the internal firewalls and network address translation (NAT) routers of the network unintentionally contribute to hiding the bots’ host address and malicious packets. However, eliminating firewalls and NAT routers merely for locating bots is generally not acceptable. In the present paper, we propose an easy to deploy, easy to manage network security control system for locating a malicious host behind internal secure gateways. The proposed network security control system consists of a remote security device and a command server. The remote security device is installed as a transparent link (implemented as an L2 switch), between the subnet and its gateway in order to detect a host that has been compromised by a malicious bot in a target subnet, while minimizing the impact of deployment. The security device is controlled remotely by 'polling' the command server in order to eliminate the NAT traversal problem and to be firewall friendly. Since the remote security device exists in transparent, remotely controlled, robust security gateways, we regard this device as a beneficial bot. We adopt a web server with wiki software as the command server in order to take advantage of its power of customization, ease of use, and ease of deployment of the server.	5	0
Estado del arte de la investigación sobre wikis	Emilio J. Rodríguez-Posada Juan Manuel Dodero-Beardo		University of Cádiz	Spanish	December 2012	El interés de los investigadores por los wikis, en especial Wikipedia, ha ido en aumento en los últimos años. La primera edición de WikiSym, un simposio sobre wikis, se celebró en 2005 y desde entonces han aparecido multitud de congresos, workshops, conferencias y competiciones en este área. El estudio de los wikis es un campo emergente y prolífico. Ha habido varios intentos, aunque con escaso éxito, de recopilar toda la literatura sobre wikis. Unas veces el enfoque o la herramienta utilizada eran limitados, otras debido a las dimensiones de la tarea el proyecto era abandonado y al poco tiempo los metadatos bibliográficos se perdían. En este trabajo presentamos WikiPapers, un proyecto colaborativo para recopilar toda la literatura sobre wikis. Se hace uso de MediaWiki y su extensión semántica, ambos conocidos por los investigadores de este campo. Hasta noviembre de 2012 se han recopilado más de 1.700 publicaciones y sus metadatos, además de documentación sobre herramientas y datasets relacionados. Los metadatos son exportables en los formatos BibTeX, RDF, CSV y JSON. Los historiales completos del wiki están disponibles para descargar y facilitar su preservación. El proyecto está abierto a la participación de todo el mundo. El resto del trabajo se divide de la siguiente manera. En la sección 2 motivamos este trabajo haciendo un repaso a los distintos enfoques utilizados hasta ahora para recopilar toda la literatura sobre wikis, incidiendo en sus ventajas e inconvenientes. En la sección 3 detallamos los objetivos. En la sección 4 definimos algunos términos que servirán para comprender mejor el contenido. En la sección 5 presentamos WikiPapers, cómo funciona y qué pasos se han dado. En la sección 6 hacemos un estado del arte empleando WikiPapers. En la sección 7 repasamos las cuestiones que a día de hoy siguen abiertas o que han tenido poca atención hasta ahora. Finalmente, en la sección 8, terminamos con unas conclusiones y trabajo futuro.	0	0
Mass Collaboration or Mass Amateurism? A comparative study on the quality of scientific information produced using Wiki tools and concepts	Fernando Rodrigues	Mass Collaboration Collective intelligence Crowdsourcing Information Systems Data Quality Wikipedia Encyclopaedia Britannica	Universidade Évora	Portuguese	December 2012	With this PhD dissertation, we intend to contribute to a better understanding of the Wiki phenomenon as a knowledge management system which aggregates private knowledge. We also wish to check to what extent information generated through anonymous and freely bestowed mass collaboration is reliable as opposed to the traditional approach. In order to achieve that goal, we develop a comparative study between Wikipedia and Encyclopaedia Britannica with regard to accuracy, depth and detail of information in both, in order to confront the quality of the knowledge repository produced by them. That will allow us to reach a conclusion about the efficacy of the business models behind them. We will use a representative random sample which is composed by the articles that are comprised in both encyclopedias. Each pair of articles was previously reformatted and then graded by an expert in its subject area. At the same time, we collected a small convenience sample which only integrates Management articles. Each pair of articles was graded by several experts in order to determine the uncertainty associated with having diverse gradings of the same article and apply it to the evaluations carried out by just one expert. The conclusion was that the average quality of the Wikipedia articles which were analysed was superior to its peers’ and that this difference was statistically significant. An inquiry was conducted within the academia which certified that traditional information sources were used by a minority as the first approach to seeking information. This inquiry also made clear that reliance on these sources was considerably larger than reliance on information obtained through Wikipedia. This quality perception, as well as the diametrically opposed results of its evaluation through a blind test, reinforces the evaluating panel’s exemption. However much the chosen sample is representative of the universe to be studied, results have depended on the evaluators’ personal opinion and chosen criteria. This means that the reproducibility of this study’s conclusions using a different grading panel cannot be guaranteed. Nevertheless, this is not enough of a reason to reject the study results obtained through more than five hundred evaluations. This thesis is thus an attempt to help clarifying this topic and contributing to a better perception of the quality of a tool which is daily used by millions of people, of the mass collaboration which feeds it and of the collaborative software that supports it.	0	0

A M2M system using Arduino, Android and Wiki Software	Takashi Yamanoue Kentaro Oda Koichi Shimozono	Wiki Social network	IIAI ESKM	English	September 2012	A Machine-to-Machine (M2M) system, which uses Arduino, Android, and Wiki software, is discussed. ["proposed"?] This system consists of mobile terminals and web sites with wiki software. A mobile terminal of the system consists of an Android terminal and an Arduino board with sensors and actuators. The mobile terminal reads data from the sensors in the Arduino board and sends the data to a wiki page. The mobile terminal also reads commands on the wiki page and controls the actuators of the Arduino board. In addition, a wiki page can have a program that reads the page and outputs information such as a graph. This system realizes an open communication forum for not only people but also for machines	4	0
Wikipédia, espace fluide, espace à parcourir	Rémi Mathis	Wikipedia	La Revue de la BNU	French	September 2012	Wikipédia est un espace foncièrement décentré : qui existe en plus de 280 langues, où les auteurs se comptent en centaines de milliers, qui évolue sans cesse pour coller au dernier état du savoir. Afin de faciliter la navigation, des portes d'entrée sont créées et des outils permettent de structurer cet espace. L'idée n'est toutefois pas d'imposer un parcours mais bien au contraire de favoriser la fluidité de la lecture, par des itinéraires sans cesse réinventés par les lecteurs - tendant à enrichir son expérience de découverte et l'amener vers des articles qu'ils n'aurait pas cherché par lui-même.	0	0

Citation needed: The dynamics of referencing in Wikipedia	Chih-Chun Chen Camille Roth	Wikipedia Collaborative system Authority	WikiSym		August 2012	The extent to which a Wikipedia article refers to external sources to substantiate its content can be seen as a measure of its externally invoked authority. We introduce a protocol for characterising the referencing process in the context of general article editing. With a sample of relatively mature articles, we show that referencing does not occur regularly through an article’s lifetime but is associated with periods of more substantial editing, when the article has reached a certain level of maturity (in terms of the number of times it has been revised and its length). References also tend to be contributed by editors who have contributed more frequently and more substantially to an article, suggesting that a subset of more qualified or committed editors may exist for each article.	0	0
Classifying Wikipedia Articles Using Network Motif Counts and Ratios	Guangyu Wu Martin Harrigan Pádraig Cuningham	Quality Edit Networks	WikiSym	English	August 2012	Because the production of Wikipedia articles is a collaborative process, the edit network around a article can tell us something about the quality of that article. Articles that have received little attention will have sparse networks; at the other end of the spectrum, articles that are Wikipedia battle grounds will have very crowded networks. In this paper we evaluate the idea of characterizing edit networks as a vector of motif counts that can be used in clustering and classification. Our objective is not immediately to develop a powerful classifier but to assess what is the signal in network motifs. We show that this motif count vector representation is effective for classifying articles on the Wikipedia quality scale. We further show that ratios of motif counts can effectively overcome normalization problems when comparing networks of radically different sizes.	0	0
Deletion Discussions in Wikipedia: Decision Factors and Outcomes	Jodi Schneider Alexander Passant Stefan Decker	Collaboration and conflict Decision-making Wikipedia Articles for Deletion Factors analysis Online argumentation Values Novices	WikiSym	English	August 2012	Deletion of articles is a common process in Wikipedia, in order to ensure the overall quality of the encyclopedia. Yet, there is a need to better understand the procedures in order to promote the best decisions without unnecessary community work. In this paper, we study deletion in Wikipedia, drawing from factor analysis, and taking an in-depth, content-analysis-based approach. We address three research questions: First, what factors contribute to the decision about whether to delete a given article? Second, when multiple factors are given, what is the relative importance of those factors? Third, what are the outcomes of deletion discussions, both for articles and for the community? We find that multiple factors contribute to the assessment of an article, and we discuss their relative frequency. Further, we show how the assessment timeline focuses attention on improving borderline articles that have the potential to meet Wikipedia’s content inclusion policies, and we highlight the role of novice contributors in this improvement process.	0	0
Design for Free Learning - a Case Study on Supporting a Service Design Course	Teresa Consiglio Gerrit C. van der Veer	Experience report Open source Cultural diversity E- learning Service design Learner centered design	WikiSym		August 2012	In this experience report, we provide a case study on the use of information and communication technology (ICT) in higher education, developing an open source interactive learning environment to support a blended course. Our aim is to improve the quality of adult distance learning, ultimately involving peers worldwide, by developing learning invironments as flexible as possible regardless of the culture and context of use, of individual learning style and age of the learners. Our example concerns a course of Service Design where the teacher was physically present only intermittently for part of the course while in the remaining time students worked in teams using our online learning environment. We developed a structure where students are guided through discovery learning and mutual teaching. We will show how we started from the students’ authentic goals and how we supported them by a simple structure of pacing the discovery process and merging theoretical understanding with practice in real life. Based on these first empirical results practical guidelines have been developed regarding improvements on the structure provided for the learning material and on the interaction facilities for students, teachers and instructional designers.	0	0
Drawing a Data-Driven Portrait of Wikipedia Editors	Robert West Ingmar Weber Carlos Castillo	Wikipedia Editors Web usage Expertise	WikiSym	English	August 2012	While there has been a substantial amount of research into the editorial and organizational processes within Wikipedia, little is known about how Wikipedia editors (Wikipedians) relate to the online world in general. We attempt to shed light on this issue by using aggregated log data from Yahoo!’s browser toolbar in order to analyze Wikipedians’ editing behavior in the context of their online lives beyond Wikipedia. We broadly characterize editors by investigating how their online behavior differs from that of other users; e.g., we find that Wikipedia editors search more, read more news, play more games, and, perhaps surprisingly, are more immersed in popular culture. Then we inspect how editors’ general interests relate to the articles to which they contribute; e.g., we confirm the intuition that editors are more familiar with their active domains than average users. Finally, we analyze the data from a temporal perspective; e.g., we demonstrate that a user’s interest in the edited topic peaks immediately before the edit. Our results are relevant as they illuminate novel aspects of what has become many Web users’ prevalent source of information.	0	0
Etiquette in Wikipedia: Weening New Editors into Productive Ones	Ryan Faulkner Steven Walling Maryana Pinchuk	Wikipedia Huggle Newcomers Vandalism Wiki Retention	WikiSym	English	August 2012	Currently, the greatest challenge faced by the Wikipedia community involves reversing the decline of active editors on the site – in other words, ensuring that the encyclopedia’s contributors remain sufficiently numerous to fill the roles that keep it relevant. Due to the natural drop-off of old contributors, newcomers must constantly be socialized, trained and retained. However recent research has shown the Wikipedia community is failing to retain a large proportion of productive new contributors and implicates Wikipedia’s semi-automated quality control mechanisms and their interactions with these newcomers as an exacerbating factor. This paper evaluates the effectiveness of minor changes to the normative warning messages sent to newcomers from one of the most prolific of these quality control tools (Huggle) in preserving their rate of contribution. The experimental results suggest that substantial gains in newcomer participation can be attained through inexpensive changes to the wording of the first normative message that new contributors receive.	0	0
How Long Do Wikipedia Editors Keep Active?	Dell Zhang Karl Prior Mark Levene	Social Media User Modelling Behaviour Mining Survival Analysis	WikiSym	English	August 2012	In this paper, we use the technique of survival analysis to investigate how long Wikipedia editors remain active in editing. Our results show that although the survival function of occasional editors roughly follows a lognormal distribution, the survival function of customary editors can be better described by a Weibull distribution (with the median lifetime of about 53 days). Furthermore, for customary editors, there are two critical phases (0-2 weeks and 8-20 weeks) when the hazard rate of becoming inactive increases. Finally, customary editors who are more active in editing are likely to keep active in editing for longer time.	0	0
Identifying controversial articles in Wikipedia: A comparative study	Hoda Sepehri Rad Denilson Barbosa	Wikipedia Controversy Disagreement Comparison Monotonicity	WikiSym	English	August 2012	Wikipedia articles are the result of the collaborative editing of a diverse group of anonymous volunteer editors, who are passionate and knowledgeable about specific topics. One can argue that this plurality of perspectives leads to broader coverage of the topic, thus benefitting the reader. On the other hand, differences among editors on polarizing topics can lead to controversial or questionable content, where facts and arguments are presented and discussed to support a particular point of view. Controversial articles are manually tagged by Wikipedia editors, and span many interesting and popular topics, such as religion, history, and politics, to name a few. Recent works have been proposed on automatically identifying controversy within unmarked articles. However, to date, no systematic comparison of these efforts has been made. This is in part because the various methods are evaluated using different criteria and on different sets of articles by different authors, making it hard for anyone to verify the efficacy and compare all alternatives. We provide a first attempt at bridging this gap. We compare five different methods for modelling and identifying controversy, and discuss some of the unique difficulties and opportunities inherent to the way Wikipedia is produced.	0	0
In Search of the Ur-Wikipedia: Universality, Similarity, and Translation in the Wikipedia Inter-Language Link Network	Morten Warncke-Wang Anuradha Uduwage Zhenhua Dong John Riedl	Wikipedia Tobler's Law First Law of Geography Multilingual	WikiSym	English	August 2012	Wikipedia has become one of the primary encyclopaedic information repositories on the World Wide Web. It started in 2001 with a single edition in the English language and has since expanded to more than 20 million articles in 283 languages. Criss-crossing between the Wikipedias is an interlanguage link network, connecting the articles of one edition of Wikipedia to another. We describe characteristics of articles covered by nearly all Wikipedias and those covered by only a single language edition, we use the network to understand how we can judge the similarity between Wikipedias based on concept coverage, and we investigate the flow of translation between a selection of the larger Wikipedias. Our findings indicate that the relationships between Wikipedia editions follow Tobler's first law of geography: similarity decreases with increasing distance. The number of articles in a Wikipedia edition is found to be the strongest predictor of similarity, while language similarity also appears to have an influence. The English Wikipedia edition is by far the primary source of translations. We discuss the impact of these results for Wikipedia as well as user-generated content communities in general.	0	0
Manypedia: Comparing Language Points of View of Wikipedia Communities	Paolo Massa Federico Scrinzi	Wikipedia Cross-cultural comparison Linguistic Point of View Language Automatic translation Web tool Open source	WikiSym	English	August 2012	The 4 million articles of the English Wikipedia have been written in a collaborative fashion by more than 16 million volunteer editors. On each article, the community of editors strive to reach a neutral point of view, representing all significant views fairly, proportionately, and without biases. However, beside the English one, there are more than 280 editions of Wikipedia in different languages and their relatively isolated communities of editors are not forced by the platform to discuss and negotiate their points of view. So the empirical question is: do communities on different language Wikipedias develop their own diverse Linguistic Points of View (LPOV)? To answer this question we created and released as open source Manypedia, a web tool whose aim is to facilitate cross-cultural analysis of Wikipedia language communities by providing an easy way to compare automatically translated versions of their different representations of the same topic.	0	0
Mutual Evaluation of Editors and Texts for Assessing Quality of Wikipedia Articles	Yu Suzuki Masatoshi Yoshikawa	Wikipedia Quality Peer review Edit history Link analysis	WikiSym	English	August 2012	In this paper, we propose a method to identify good quality Wikipedia articles by mutually evaluating editors and texts. A major approach for assessing article quality is a text survival ratio based approach. In this approach, when a text survives beyond multiple edits, the text is assessed as good quality. This approach assumes that poor quality texts are deleted by editors with high possibility. However, many vandals delete good quality texts frequently, then the survival ratios of good quality texts are improperly decreased by vandals. As a result, many good quality texts are unfairly assessed as poor quality. In our method, we consider editor quality for calculating text quality, and decrease the impacts on text qualities by the vandals who has low quality. Using this improvement, the accuracy of the text quality should be improved. However, an inherent problem of this idea is that the editor qualities are calculated by the text qualities. To solve this problem, we mutually calculate the editor and text qualities until they converge. We did our experimental evaluation, and we confirmed that the proposed method could accurately assess the text qualities.	0	0
Natural Language Processing for MediaWiki: The Semantic Assistants Approach	Bahar Sateli René Witte		WikiSym	English	August 2012	We present a novel architecture for the integration of Natural Language Processing (NLP) capabilities into wiki systems. The vision is that of a new generation of wikis that can help developing their own primary content and organize their structure by using state-of-the-art technologies from the NLP and Semantic Computing domains. The motivation for this integration is to enable wiki users – novice or expert – to benefit from modern text mining techniques directly within their wiki environment. We implemented these ideas based on MediaWiki and present a number of real-world application case studies that illustrate the practicability and effectiveness of this approach.	0	0
On the Accuracy of Urban Crowd-Sourcing for Maintaining Large-Scale Geospatial Databases	Afra Mashhadi Giovanni Quattrone Licia Capra Peter Mooney	Human Factors Measurement Reliability	WikiSym	English	August 2012	The world is in the midst of an immense population shift from rural areas to cities. Urban elements, such as businesses, Points-of-Interest (POIs), transportation, and housing are continuously changing, and collecting and maintaining accurate information about these elements within spatial databases has become an incredibly onerous task. A solution made possible by the uptake of social media is crowd-sourcing, where user-generated content can be cultivated into meaningful and informative collections, as exemplified by sites like Wikipedia. This form of user-contributed content is no longer confined to the Web: equipped with powerful mobile devices, citizens have become cartographers too, volunteering geographic information (e.g., POIs) as exemplified by sites like OpenStreetMap. In this paper, we investigate the extent to which crowd-sourcing can be relied upon to build and maintain an accurate map of the changing world, by means of a thorough analysis and comparison between traditional web-based crowd-sourcing (as in Wikipedia) and urban crowd-sourcing (as in OpenStreetMap).	17	0
Psychological processes underlying Wikipedia representations of natural and manmade disasters	Michela Ferron Paolo Massa	Collective memory Traumatic event Man-made disasters Natural disasters LIWC Automated content analysis techniques	WikiSym	English	August 2012	Collective memories are precious resources for the society, because they help strengthening emotional bonding between community members, maintaining groups cohesion, and directing future behavior. Studying how people form their collective memories of emotional upheavals is important in order to better understand people's reactions and the consequences on their psychological health. Previous research investigated the effects of single traumatizing events, but few of them tried to compare different types of traumatic events like natural and man-made disasters. In this paper, interpreting Wikipedia as a collective memory place, we compare articles about natural and human-made disasters employing automated natural language techniques, in order to highlight the different psychological processes underlying users' sensemaking activities.	0	0
Staying in the Loop: Structure and Dynamics of Wikipedia's Breaking News Collaborations	Brian Keegan Darren Gergle Noshir Contractor	Wikipedia High-tempo collaboration Network analysis Breaking news Collaboration Multigraph	WikiSym	English	August 2012	Despite the fact that Wikipedia articles about current events are more popular and attract more contributions than typical articles, canonical studies of Wikipedia have only analyzed articles about pre-existing information. We expect the co-authoring of articles about breaking news incidents to exhibit high-tempo coordination dynamics which are not found in articles about historical events and information. Using 1.03 million revisions made by 158,384 users to 3,233 English Wikipedia articles about disasters, catastrophes, and conflicts since 1990, we construct “article trajectories” of editor interactions as they coauthor an article. Examining a subset of this corpus, our analysis demonstrates that articles about current events exhibit structures and dynamics distinct from those observed among articles about non-breaking events. These findings have implications for how collective intelligence systems can be leveraged to process and make sense of complex information.	0	0
Towards Content-driven Reputation for Collaborative Code Repositories	Andrew G. West Insup Lee	WikiTrust Wiki Code repository SVN Reputation Trust management Content persistence Code quality	WikiSym	English	August 2012	As evidenced by SourceForge and GitHub, code repositories now integrate Web 2.0 functionality that enables global participation with minimal barriers-to-entry. To prevent detrimental contributions enabled by crowdsourcing, reputation is one proposed solution. Fortunately this is an issue that has been addressed in analogous version control systems such as the *wiki* for natural language content. The WikiTrust algorithm ("content-driven reputation"), while developed and evaluated in wiki environments operates under a possibly shared collaborative assumption: actions that "survive" subsequent edits are reflective of good authorship. In this paper we examine WikiTrust's ability to measure author quality in collaborative code development. We first define a mapping from repositories to wiki environments and use it to evaluate a production SVN repository with 92,000 updates. Analysis is particularly attentive to reputation loss events and attempts to establish ground truth using commit comments and bug tracking. A proof-of-concept evaluation suggests the technique is promising (about two-thirds of reputation loss is justified) with false positives identifying areas for future refinement. Equally as important, these false positives exemplify differences in content evolution and the cooperative process between wikis and code repositories.	0	0
Wikipedia Customization through Web Augmentation Techniques	Oscar Díaz Cristóbal Arellano Gorka Puente	Web Augmentation Wiki DSL	WikiSym	English	August 2012	Wikipedia is a successful example of collaborative knowledge construction. This can be synergistically complemented with personal knowledge construction whereby individuals are supported in their sharing, experimenting and building of information in a more private setting, without the scrutiny of the whole community. Ideally, both approaches should be seamlessly integrated so that wikipedians can easily transit from the public sphere to the private sphere, and vice versa. To this end, we introduce WikiLayer, a plugin for Wikipedia that permits wikipedians locally supplement Wikipedia articles with their own content (i.e. a layer). Layering additional content is achieved locally by seamlessly interspersing Wikipedia content with custom content. WikiLayer is driven by three main wiki principles: affordability (i.e., if you know how to edit articles, you know how to layer), organic growth (i.e., layers evolve in synchrony with the underlying articles) and shareability (i.e., layers can be shared in confidence through the wikipedian’s social network, e.g., Facebook ). The paper provides motivating scenarios for readers, contributors and editors. WikiLayer is available for download at http://webaugmentation.org/wikilayer.xpi.	0	0

Writing up rather than writing down: Becoming Wikipedia Literate	Heather Ford R. Stuart Geiger	Literacy Wikipedia New literacies Educational technology Ethnography	WikiSym	English	August 2012	Editing Wikipedia is certainly not as simple as learning the MediaWiki syntax and knowing where the “edit” bar is, but how do we conceptualize the cultural and organizational understandings that make an effective contributor? We draw on work of literacy practitioner and theorist Richard Darville to advocate a multi-faceted theory of literacy that sheds light on what new knowledges and organizational forms are required to improve participation in Wikipedia’s communities. We outline what Darville refers to as the “background knowledges” required to be an empowered, literate member and apply this to the Wikipedia community. Using a series of examples drawn from interviews with new editors and qualitative studies of controversies in Wikipedia, we identify and outline several different literacy asymmetries.	0	0

A Casual Network Security Monitoring System using a Portable Sensor Device and Wiki Software	Takashi Yamanoue Kentaro Oda Koichi Shimozono	Wiki Information security	SAINT	English	July 2012	A casual network security monitoring system is proposed in this paper. The system is easy to deploy without reconfiguring the central network infrastructure, the firewall, and the intrusion detector system (IDS) of an organization. A virus-infected host, which is hidden by the network address translator (NAT) of a sub LAN, can be identified easily by using this monitoring system with the IDS. This monitoring system consists of a portable sensor device and a web site with wiki software. The portable sensor device, which is located on a target LAN that may have virus-infected hosts, is remote-controlled by a network manager's commands. The commands and the results are written on a wiki page.	3	1
Análisis de enlaces hacia Bibliotecas y Archivos Digitales de Patrimonio Cultural desde Wikipedia en español y catalán	Tomás Saorín-Pérez Emilio J. Rodríguez-Posada		BiD: textos universitaris de biblioteconomia i documentació	Spanish	July 2012	Objetivo. Describir y evaluar el uso en Wikipedia de enlaces a las colecciones digitalizadas en bibliotecas, archivos y otras instituciones culturales. Metodología. El estudio se realiza sobre la totalidad de los artículos de las ediciones en español y catalán de Wikipedia, usando una herramienta de análisis de wikis. Se realiza una selección amplia de 81 colecciones digitales españolas de diferente alcance. También se toman datos de otros proyectos de digitalización para poder comparar los resultados. Resultados. Se muestra una presencia aún débil de enlaces desde Wikipedia, excepto para la Biblioteca Virtual Miguel de Cervantes, cuyas magnitudes son sensiblemente diferentes. Algunas colecciones especializadas son más usadas, pero en general se aprecia una falta de atención hacia estas colecciones desde el colectivo de editores de Wikipedia, lo cual debería tenerse en cuenta en el desarrollo de los proyectos de digitalización tipo Europeana.	5	0
Wikipedia de la A a la W	Tomás Saorín-Pérez	Wikipedia Wikimedia projects Encyclopedia	Editorial UOC	Spanish	July 2012	Wikipedia es una realidad que funciona, aunque en teoría pueda parecer un sueño irrealizable. Un puñado de entusiastas ha redefinido desde la nada el concepto clásico de enciclopedia y ha construido la fuente de referencia más usada de la historia. ¿Tiene suficiente calidad? La respuesta es afirmativa, y para justificarlo hay que profundizar en los mecanismos de los que está dotada, que le permiten alcanzar el nivel de calidad que se desee, combinando el esfuerzo de miles de editores voluntarios autoorganizados. Wikipedia es al mismo tiempo contenido y personas. Es el momento de conocerla por dentro y de potenciar su apuesta por el conocimiento abierto desde las instituciones culturales, científicas y educativas. Participar en Wikipedia permite aprender de este increíble laboratorio global de construcción social de información organizada.	0	0

Dynamics of Conflicts in Wikipedia	Taha Yasseri Róbert Sumi András Rung András Kornai János Kertész		PLoS ONE	English	June 2012	In this work we study the dynamical features of editorial wars in Wikipedia (WP). Based on our previously established algorithm, we build up samples of controversial and peaceful articles and analyze the temporal characteristics of the activity in these samples. On short time scales, we show that there is a clear correspondence between conflict and burstiness of activity patterns, and that memory effects play an important role in controversies. On long time scales, we identify three distinct developmental patterns for the overall behavior of the articles. We are able to distinguish cases eventually leading to consensus from those cases where a compromise is far from achievable. Finally, we analyze discussion networks and conclude that edit wars are mainly fought by few editors only.	44	1
Reverts Revisited: Accurate Revert Detection in Wikipedia	Fabian Flöck Denny Vrandečić Elena Simperl	Wikipedia Revert detection Editing behavior User modeling Collaboration systems Community-driven content creation Social dynamics	Hypertext and Social Media 2012	English	June 2012	Wikipedia is commonly used as a proving ground for research in collaborative systems. This is likely due to its popularity and scale, but also to the fact that large amounts of data about its formation and evolution are freely available to inform and validate theories and models of online collaboration. As part of the development of such approaches, revert detection is often performed as an important pre-processing step in tasks as diverse as the extraction of implicit networks of editors, the analysis of edit or editor features and the removal of noise when analyzing the emergence of the con-tent of an article. The current state of the art in revert detection is based on a rather naïve approach, which identifies revision duplicates based on MD5 hash values. This is an efficient, but not very precise technique that forms the basis for the majority of research based on revert relations in Wikipedia. In this paper we prove that this method has a number of important drawbacks - it only detects a limited number of reverts, while simultaneously misclassifying too many edits as reverts, and not distinguishing between complete and partial reverts. This is very likely to hamper the accurate interpretation of the findings of revert-related research. We introduce an improved algorithm for the detection of reverts based on word tokens added or deleted to adresses these drawbacks. We report on the results of a user study and other tests demonstrating the considerable gains in accuracy and coverage by our method, and argue for a positive trade-off, in certain research scenarios, between these improvements and our algorithm’s increased runtime.	13	0

Online open neuroimaging mass meta-analysis	Finn Årup Nielsen Matthew J. Kempton Steven C. R. Williams	Wiki MediaWiki Meta-analysis Neuroimaging	SePublica 2012	English	May 2012	We describe a system for meta-analysis where a wiki stores numerical data in a simple format and a web service performs the numerical computation. We initially apply the system on multiple meta-analyses of structural neuroimaging data results. The described system allows for mass meta-analysis, e.g., meta-analysis across multiple brain regions and multiple mental disorders.	2	0
Panorama of the wikimediasphere	David Gómez-Fontanills	Wikimedia Wikipedia MediaWiki Free community good Communities of editors Editorial autonomy Libre software	Digithum	English Catalan	May 2012	The term wikimediasphere is proposed to refer to the group of WikiProjects, communities of editors, guidelines and organisations structured around the Wikimedia movement to generate free knowledge that is available to everyone. A description is made of the wikimediasphere, presenting the main projects and their characteristics, and its community, technological, regulatory, social and institutional dimensions are outlined. The wikimediasphere is placed in context and reference is made to its blurred boundaries. An explanation is provided of the role of the communities of editors of each project and their autonomy with respect to each other and to the Wikimedia Foundation. The author concludes by offering a panoramic view of the wikimediasphere.	10	0
The Truth of Wikipedia	Nathaniel Tkacz	Wikipedia Neutral point of view Truth Collaboration	Digithum	English Catalan	May 2012	What does it mean to assert that Wikipedia has a relation to truth? That there is, despite regular claims to the contrary, an entire apparatus of truth in Wikipedia? In this article, I show that Wikipedia has in fact two distinct relations to truth: one which is well known and forms the basis of existing popular and scholarly commentaries, and another which refers to equally well-known aspects of Wikipedia, but has not been understood in terms of truth. I demonstrate Wikipedia’s dual relation to truth through a close analysis of the Neutral Point of View core content policy (and one of the project’s “Five Pillars”). I conclude by indicating what is at stake in the assertion that Wikipedia has a regime of truth and what bearing this has on existing commentaries.	7	0
Using Wikipedia to develop language resources: WordNet 3.0 in Catalan and Spanish	Antoni Oliver Salvador Climent	Wikipedia WordNet Natural Language Processing Linguistic resources	Digithum	English Catalan	May 2012	We describe the state of the art in the use of Wikipedia for natural language processing tasks and also describe three applications of our own that enrich a powerful language resource: WordNet version 3.0 in Catalan and Spanish. Researchers have for many years sought applications that would take account of world knowledge in a more or less structured way, as this kind of knowledge has proven to be crucial to satisfactorily solving certain language processing tasks. Wikipedia may be the answer to the provision of this kind of information, as it is constantly updated and access is free.	17	0
Wiki Loves Monuments 2011: the experience in Spain and reflections regarding the diffusion of cultural heritage	Emilio J. Rodríguez-Posada Ángel González Berdasco Jorge A. Sierra Canduela Santiago Navarro Sanz Tomás Saorín-Pérez	Wiki Loves Monuments Cultural heritage Image bank Wikimedia Commons Libre knowledge Photography	Digithum	Spanish Catalan English	May 2012	Wikipedia came into being in cyberspace. Its early years were marked by asynchronous work by users located all over the world who hardly ever related on a personal level outside the net. With time, some of the volunteers met at what were called wikimeetups, encounters initially aimed at tightening bonds which did not bring about any direct improvement to the project content. Face-to-face initiatives later took place that involved not just volunteers but also cultural entities. The most recent event and the one with the greatest impact was Wiki Loves Monuments 2011, a competition to photograph monuments in 18 European countries, including Spain. The high level of participation led to 160,000 photographs of monuments being taken, with Spain occupying the third place in terms of number of photographs. In this paper we explore the origins, implementation, development and results of Wiki Loves Monuments. The success of the 2011 edition and requests from other countries has led to organization of Wiki Loves Monuments 2012, which will be held at the global level.	3	0
Wikipedia's Role in Reputation Management: An Analysis of the Best and Worst Companies in the USA	Marcia W. DiStaso Marcus Messner	Wikipedia Reputation management United States Monitor Social media	Digithum	English Catalan	May 2012	Being considered one of the best companies in the USA is a great honor, but this reputation does not exempt businesses from negativity in the collaboratively edited online encyclopedia Wikipedia. Content analysis of corporate Wikipedia articles for companies with the best and worst reputations in the USA revealed that negative content outweighed positive content irrespective of reputation. It was found that both the best and the worst companies had more negative than positive content in Wikipedia. This is an important issue because Wikipedia is not only one of the most popular websites in the world, but is also often the first place people look when seeking corporate information. Although there was more content on corporate social responsibility in the entries for the ten companies with the best reputations, this was still overshadowed by content referring to legal issues or scandals. Ultimately, public relations professionals need to regularly monitor and request updates to their corporate Wikipedia articles regardless of what kind of company they work for.	0	0

Secure Wiki System: A plugin-based solution to wiki security	Kasper Lindberg			English	March 2012	Wiki systems have become an important tool for knowledge sharing among people. From the small wikis for knowledge sharing in organizations to the larger project-related wikis on the Internet. In addition, Wikipedia, which is in a class of its own when it comes to size, has managed to collect an impressive amount of information based solely on the cooperation between strangers from around the world. Any open wiki, with a user-community so large that members of the community have a certain degree of anonymity, suffer from the effects of directed and random vandalism. This vandalism is a problem because it reduces the trustworthiness of the content provided by the wiki system. The secure wiki model is an integrity model that has been proposed to help prevent vandalism and improve the trustworthiness of articles in wiki system. This model is based on both static and dynamic document access controls, which enforce a simple integrity based security policy. This thesis improves this model by proposing a new policy for use with the model. The proposed policy is evaluated and compared to the original policy. The evaluation shows that the new policy is highly configurable and can be configured in such a way that it requires significantly less reviewers than the original policy, which can benefit small systems with a low number of users. An implementation of a base wiki system have been created, which on its own equals any other wiki in terms of its vulnerability to vandalism. In addition to this, an implementation of the secure wiki model has also been created. The implementation is made as a plugin to the base wiki system and adds an integrity model to the existing soft-security model that is used by the base system and other wiki implementations. The integrity model provides harder security guarantees and limits the ability of attackers to compromise the integrity of wiki articles, without compromising the all can edit policy of open wiki systems.	6	0
Spamming for Science: Active Measurement in Web 2.0 Abuse Research	Andrew G. West Pedram Hayati Vidyasagar Potdar Insup Lee		WECSR	English	March 2012	Spam and other electronic abuses have long been a focus of computer security research. However, recent work in the domain hasemphasized an *economic analysis* of these operations in the hope of understanding and disrupting the profit model of attackers. Such studies do not lend themselves to passive measurement techniques. Instead, researchers have become middle-men or active participants in spam behaviors; methodologies that lie at an interesting juncture of legal, ethical, and human subject (e.g., IRB) guidelines. In this work two such experiments serve as case studies: One testing a novel link spam model on Wikipedia and another using blackhat software to target blog comments and forums. Discussion concentrates on the experimental design process, especially as influenced by human-subject policy. Case studies are used to frame related work in the area, and scrutiny reveals the computer science community requires greater consistency in evaluating research of this nature.	0	0
Open Wikis and the Protection of Institutional Welfare	Andrew G. West Insup Lee		EDUCAUSE Center for Applied Research, Research Bulletins	English	7 February 2012	Much has been written about wikis’ reliability and use in the classroom. This research bulletin addresses the negative impacts on institutional welfare that can arise from participating in and supporting wikis. The open nature of the platform, which is fundamental to wiki operation and success, enables these negative consequences. A finite user base that can be determined a priori (e.g., a course roster) minimizes the security implications, hence our discussion in this bulletin primarily concerns open or public wikis that accept contributions from a broad and unknown set of Internet users.	0	0
Valorisation du bénévolat sur Wikipédia	Vincent Juhel			French	February 2012	Wikipédia a un fonctionnement atypique dont les recherches s’attardent majoritairement autour de la qualité des articles potentiellement rédigés par n’importe qui. J’ai cherché par cette thèse professionnelle à présenter un regard quantitatif et qualitatif de la véritable valeur que ce projet apporte aux lecteurs, rédacteurs, donateurs mais également ce qu’il aurait représenté s’il avait été une entreprise classique. Le premier objectif était d’évaluer la valeur du travail de ces bénévoles, qui, en dépit sa gratuité, apporte une véritable richesse. Mieux définir cette richesse, c’est aussi mieux convaincre les donateurs et avoir plus de poids vis à vis des partenaires. Le deuxième objectif a été de définir les contours d’une stratégie cherchant à maximiser la valeur produite par une communauté de bénévoles en grande partie autogérée. Mieux maîtriser la valeur produite pour mieux orienter et motiver le travail des contributeurs.	0	0
A Breakdown of Quality Flaws in Wikipedia	Maik Anderka Benno Stein	Quality Flaws Information quality Wikipedia User-generated Content Analysis	2nd Joint WICOW/AIRWeb Workshop on Web Quality (WebQuality 12)	English	2012	The online encyclopedia Wikipedia is a successful example of the increasing popularity of user generated content on the Web. Despite its success, Wikipedia is often criticized for containing low-quality information, which is mainly attributed to its core policy of being open for editing by everyone. The identification of low-quality information is an important task since Wikipedia has become the primary source of knowledge for a huge number of people around the world. Previous research on quality assessment in Wikipedia either investigates only small samples of articles, or else focuses on single quality aspects, like accuracy or formality. This paper targets the investigation of quality flaws, and presents the first complete breakdown of Wikipedia's quality flaw structure. We conduct an extensive exploratory analysis, which reveals (1) the quality flaws that actually exist, (2) the distribution of flaws in Wikipedia, and (3) the extent of flawed content. An important finding is that more than one in four English Wikipedia articles contains at least one quality flaw, 70% of which concern article verifiability.	0	0
A Cross-Lingual Dictionary for English Wikipedia Concepts	Valentin I. Spitkovsky Angel X. Chang	Information retrieval Entity linking Wikipedia	Proceedings of the Eighth International Conference on Language Resources and Evaluation	English	2012	We present a resource for automatically associating strings of text with English Wikipedia concepts. Our machinery is bi-directional, in the sense that it uses the same fundamental probabilistic methods to map strings to empirical distributions over Wikipedia articles as it does to map article URLs to distributions over short, language-independent strings of natural language text. For maximal interoperability, we release our resource as a set of flat line-based text files, lexicographically sorted and encoded with UTF-8. These files capture joint probability distributions underlying concepts (we use the terms article, concept and Wikipedia URL interchangeably) and associated snippets of text, as well as other features that can come in handy when working with Wikipedia articles and related information.	5	0
A Simple Application Program Interface for Saving Java Program Data on a Wiki	Takashi Yamanoue Kentaro Oda Koichi Shimozono	Wiki Collaboration E-learning	Advances in Software Engineering	English	2012	A simple application program interface (API) for Java programs running on a wiki is implemented experimentally. A Java program with the API can be running on a wiki, and the Java program can save its data on the wiki. The Java program consists of PukiWiki, which is a popular wiki in Japan, and a plug-in, which starts up Java programs and classes of Java. A Java applet with default access privilege cannot save its data at a local host. We have constructed an API of applets for easy and unified data input and output at a remote host. We also combined the proposed API and the wiki system by introducing a wiki tag for starting Java applets. It is easy to introduce new types of applications using the proposed API. We have embedded programs such as a simple text editor, a simple music editor, a simple drawing program, and programming environments in a PukiWiki system using this API.	10	3
A Wikipedia-based corpus reference tool	Jason Ginsburg	Corpus Language teaching Wikipedia	HCCE	English	2012	This paper describes a dictionary-like reference tool that is designed to help users find information that is similar to what one would find in a dictionary when looking up a word, except that this information is extracted automatically from large corpora. For a particular vocabulary item, a user can view frequency information, part-of-speech distribution, word-forms, definitions, example paragraphs and collocations. All of this information is extracted automatically from corpora and most of this information is extracted from Wikipedia. Since Wikipedia is a massive corpus covering a diverse range of general topics, this information is probably very representative of how target words are used in general. This project has applications for English language teachers and learners, as well as for language researchers.	0	0
A practical approach to language complexity: a Wikipedia case study	Taha Yasseri András Kornai János Kertész		Submitted to PLoS ONE	English	2012	In this paper we present statistical analysis of English texts from Wikipedia (WP). We try to address the issue of language complexity empirically by comparing samples of the main English WP (Main) and the simple English WP (Simple). Simple is supposed to use a more simplified language with a limited vocabulary, and editors are explicitly requested to follow this guideline, yet in practice the vocabulary richness of both samples are at the same level. However, detailed analysis of longer units (n-grams rather than words alone) shows that the language of Simple is indeed less complex than that of Main. Comparing the two language varieties by the Gunning readability index supports this conclusion. We also report on the topical dependence of language complexity, e.g. that the language is more advanced in conceptual articles compared to person-based (biographical) and object-based articles. Finally, we investigate the relation between conflict and language complexity by analysing the content of the talk pages associated to controversial and peacefully developing articles, concluding that controversy has the effect of reducing language complexity.	0	0

Assessment of collaborative learning experiences by graphical analysis of wiki contributions	Manuel Palomo-Duarte Juan Manuel Dodero-Beardo Inmaculada Medina-Bulo Emilio J. Rodríguez-Posada Iván Ruiz-Rube	Computer-supported collaborative learning Wiki E-Learning assessment Data visualization Graphical analysis tool	Interactive Learning Environments	English	2012	The widespread adoption of computers and Internet in our life has reached the classrooms, where Computer-Supported Collaborative Learning based on wikis offers new ways of collaboration and encourages student participation. When the number of contributions from students increases, traditional assessment procedures of e-learning settings suffer from scalability problems. In a wiki-based learning experience, automatic tools are required to support the assessment of such huge amounts of data. In this work we present StatMediaWiki, a tool that collects and aggregates information that helps to analyze a MediaWiki installation. It generates charts, tables and different statistics enabling easy analysis of wiki evolution.. We have used StatMediaWiki in a Higher Education course and present the results obtained in this case study.	14	0
Automatic Vandalism Detection in Wikipedia with Active Associative Classification	Maria Sumbana Marcos André Gonçalves Rodrigo Silva Jussara Almeida Adriano Veloso		Lecture Notes in Computer Science		2012	Wikipedia and other free editing services for collaboratively generated content have quickly grown in popularity. However, the lack of editing control has made these services vulnerable to various types of malicious actions such as vandalism. State-of-the-art vandalism detection methods are based on supervised techniques, thus relying on the availability of large and representative training collections. Building such collections, often with the help of crowdsourcing, is very costly due to a natural skew towards very few vandalism examples in the available data as well as dynamic patterns. Aiming at reducing the cost of building such collections, we present a new active sampling technique coupled with an on-demand associative classification algorithm for Wikipedia vandalism detection. We show that our classifier enhanced with a simple undersampling technique for building the training set outperforms state-of-the-art classifiers such as SVMs and kNNs. Furthermore, by applying active sampling, we are able to reduce the need for training in almost 96% with only a small impact on detection results.	0	0
Bieber no more: First Story Detection using Twitter and Wikipedia	Miles Osborne Saša Petrović Richard McCreadie Craig Macdonald Iadh Ounis	Twitter Wikipedia Event Detection		English	2012	Twitter is a well known source of information regarding breaking news stories. This aspect of Twitter makes it ideal for identifying events as they happen. However, a key problem with Twitter-driven event detection approaches is that they produce many spurious events, i.e., events that are wrongly detected or simply are of no interest to anyone. In this paper, we examine whether Wikipedia (when viewed as a stream of page views) can be used to improve the quality of discovered events in Twitter. Our results suggest that Wikipedia is a powerful filtering mechanism, allowing for easy blocking of large numbers of spurious events. Our results also indicate that events within Wikipedia tend to lag behind Twitter.	0	0
Biographical Social Networks on Wikipedia: A cross-cultural study of links that made history	Pablo Aragón Andreas Kaltenbrunner David Laniado Yana Volkovich	Wikipedia Social network analysis Cross language studies	WikiSym	English	2012	It is arguable whether history is made by great men and women or vice versa, but undoubtably social connections shape history. Analysing Wikipedia, a global collective memory place, we aim to understand how social links are recorded across cultures. Starting with the set of biographies in the English Wikipedia we focus on the networks of links between these biographical articles on the 15 largest language Wikipedias. We detect the most central characters in these networks and point out culture-related peculiarities. Furthermore, we reveal remarkable similarities between distinct groups of language Wikipedias and highlight the shared knowledge about connections between persons across cultures.	0	0

Circadian patterns of Wikipedia editorial activity: A demographic analysis	Taha Yasseri Róbert Sumi János Kertész	Wikipedia Editorial activity Editors demography Circadian patterns	PLoS ONE	English	2012	Wikipedia (WP) as a collaborative, dynamical system of humans is an appropriate subject of social studies. Each single action of the members of this society, i.e. editors, is well recorded and accessible. Using the cumulative data of 34 Wikipedias in different languages, we try to characterize and find the universalities and differences in temporal activity patterns of editors. Based on this data, we estimate the geographical distribution of editors for each WP in the globe. Furthermore we also clarify the differences among different groups of WPs, which originate in the variance of cultural and social features of the communities of editors.	10	1
Classroom Wikipedia participation effects on future intentions to contribute	Cliff Lampe Jonathan Obar Elif Ozkaya Paul Zube Alcides Velasquez	Cscl Efficacy Participation Wikipedia	Computer-Supported Cooperative Work	English	2012	One of the biggest challenges faced by social media sites like Wikipedia is how to motivate users to contribute content. Research continues to demonstrate that only a small percentage of users contribute to user-generated content sites. In this study we assess the results of a Wikimedia Foundation initiative, which had graduate and undergraduate students from 22 U.S. universities contribute content to Wikipedia articles as part of their coursework. 185 students were asked about their participation in the initiative and their intention to participate on Wikipedia in the future. Results suggest that intentions to continue contributing are influenced by the initial attitude towards the class, and the degree to which students perceived they were writing for a global audience.	7	0

Conflict, criticism, or confidence: an empirical examination of the gender gap in wikipedia contributions	Benjamin Collier Julia Bear	Confidence Conflict Criticism Gender Survey Wikipedia	Computer-Supported Cooperative Work	English	2012	A recent survey of contributors to Wikipedia found that less than 15% of contributors are women. This gender contribution gap has received significant attention from both researchers and the media. A panel of researchers and practitioners has offered several insights and opinions as to why a gender gap exists in contributions despite gender anonymity online. The gender research literature suggests that the difference in contribution rates could be due to three factors: (1) the high levels of conflict in discussions, (2) dislike of critical environments, and (3) lack of confidence in editing other contributors' work. This paper examines these hypotheses regarding the existence of the gender gap in contribution by using data from an international survey of 176,192 readers, contributors, and former contributors to Wikipedia, including measures of demographics, education, motivation, and participation. Implications for improving the design and culture of online communities to be more gender inclusive are discussed.	0	0

Discipline but not punish. the governance of Wikipedia	Dominique Cardon		Normative Experience in Internet Politics	English	2012	The ways in which the Internet is managed and controlled–often labeled as Internet Governance– are usually considered as standing on four main pillars: Technology, Market Laws, State Regulation and Uses. Nevertheless, its specific features, the consequences of the plurality of norms it involves and of the decision-making processes it entails are rarely addressed in a comprehensive analysis. This book explores the Internet’s functioning both as a practical-intellectual experience and a political challenge. By means of several case studies, it proposes a substantial and reflexive treatment of multileveled, formal or informal Internet Politics.The book’s overall endeavor is to outline an understanding ofwhat is –or may be– a “digital common good”. The authors are members of a European academic team gathered by the Vox Internet research program’s meetings. They adopt a multi-disciplinary approach, embedding technological innovation in the fi eld of social sciences (communication studies, sociology, law, political science and philosophy).	0	1

Dynamics of conflicts in Wikipedia	Taha Yasseri Róbert Sumi András Rung András Kornai János Kertész		To appear in PLoS ONE	English	2012	In this work we study the dynamical features of editorial wars in Wikipedia (WP). Based on our previously established algorithm, we build up samples of controversial and peaceful articles and analyze the temporal characteristics of the activity in these samples. On short time scales, we show that there is a clear correspondence between conflict and burstiness of activity patterns, and that memory effects play an important role in controversies. On long time scales, we identify three distinct developmental patterns for the overall behavior of the articles. We are able to distinguish cases eventually leading to consensus from those cases where a compromise is far from achievable. Finally, we analyze discussion networks and conclude that edit wars are mainly fought by few editors only.	0	1
Early Prediction of Movie Box Office Success based on Wikipedia Activity Big Data	Márton Mestyán Taha Yasseri János Kertész	Prediction Big Data		English	2012	Use of socially generated "big data" to access information about collective states of the minds in human societies becomes a new paradigm in the emerging field of computational social science. One of the natural application of this would be prediction of the society's reaction to a new product in the sense of popularity and adoption rate. However, bridging between "real time monitoring" and "early predicting" remains as a big challenge. Here, we report on an endeavor to build a minimalistic predictive model for the financial success of movies based on collective activity data of online users. We show that the popularity of a movie could be predicted well in advance by measuring and analyzing the activity level of editors and viewers of the corresponding entry to the movie in Wikipedia, the well-known online encyclopedia.	0	0
Emotions and dialogue in a peer-production community: the case of Wikipedia	David Laniado Carlos Castillo Andreas Kaltenbrunner Mayo Fuster Morell	Wikipedia Talk page Emotions Gender gap	WikiSym	English	2012	This paper presents a large-scale analysis of emotions in conversations among Wikipedia editors. Our focus is on the emotions expressed by editors in talk pages, measured by using the Affective Norms for English Words (ANEW). We find evidence that to a large extent women tend to participate in discussions with a more positive tone, and that administrators are more positive than non-administrators. Surprisingly, female non-administrators tend to behave like administrators in many aspects. We observe that replies are on average more positive than the comments they reply to, preventing many discussions from spiralling down into conflict. We also find evidence of emotional homophily: editors having similar emotional styles are more likely to interact with each other. Our findings offer novel insights into the emotional dimension of interactions in peer-production communities, and contribute to debates on issues such as the flattening of editor growth and the gender gap.	0	0

Factors influencing intention to upload content on Wikipedia in South Korea: The effects of social norms and individual differences	Namkee Park Hyun S. Oh Naewon Kang		Computers in Human Behavior	English	2012	This study examined the roles of social norms and individual differences in influencing Internet users’ intention to upload content on Wikipedia in South Korea. It also compared the impacts of these variables on the uploading intention between users and non-users of Wikipedia. Using data from a survey of college students (185 Wikipedia users and 158 non-users), the study found that the effect of social norms including descriptive norm and injunctive norm was smaller than expected, while that of individual differences—self-efficacy, issue involvement, and ego involvement—was more important in accounting for the intention to upload. Theoretical implications and limitations were discussed. ⺠The study examined the factors of Internet users’ intention to upload content on Wikipedia. ⺠The effect of social norms was smaller than expected in affecting the uploading intention. ⺠Self-efficacy accounted for intention to upload content for both users and non-users of Wikipedia. ⺠Issue involvement accounted for intention to upload content for both users and non-users of Wikipedia. ⺠Ego involvement accounted for intention to upload content for both users and non-users of Wikipedia.	0	0

FlawFinder: A Modular System for Predicting Quality Flaws in Wikipedia	Oliver Ferschke Iryna Gurevych Marc Rittberger		PAN	English	2012	With over 23 million articles in 285 languages, Wikipedia is the largest free knowledge base on the web. Due to its open nature, everybody is allowed to access and edit the contents of this huge encyclopedia. As a downside of this open access policy, quality assessment of the content becomes a critical issue and is hardly manageable without computational assistance. In this paper, we present FlawFinder, a modular system for automatically predicting quality flaws in unseen Wikipedia articles. It competed in the inaugural edition of the Quality Flaw Prediction Task at the PAN Challenge 2012 and achieved the best precision of all systems and the second place in terms of recall and F1-score.	0	0

Making your database available through Wikipedia: the pros and cons	Robert D. Finn Paul P. Gardner Alex Bateman		Nucleic Acids Research	English	2012	Wikipedia, the online encyclopedia, is the most famous wiki in use today. It contains over 3.7 million pages of content; with many pages written on scientific subject matters that include peer-reviewed citations, yet are written in an accessible manner and generally reflect the consensus opinion of the community. In this, the 19th Annual Database Issue of Nucleic Acids Research, there are 11 articles that describe the use of a wiki in relation to a biological database. In this commentary, we discuss how biological databases can be integrated with Wikipedia, thereby utilising the pre-existing infrastructure, tools and above all, large community of authors (or Wikipedians). The limitations to the content that can be included in Wikipedia are highlighted, with examples drawn from articles found in this issue and other wiki-based resources, indicating why other wiki solutions are necessary. We discuss the merits of using open wikis, like Wikipedia, versus other models, with particular reference to potential vandalism. Finally, we raise the question about the future role of dedicated database biocurators in context of the thousands of crowdsourced, community annotations that are now being stored in wikis.	0	1
Massively Distributed Authorship of Academic Papers		Collaboration Writing Crowdsourcing Scholarship	CHI	English	2012	Wiki-like or crowdsourcing models of collaboration can provide a number of benefits to academic work. These techniques may engage expertise from different disciplines, and potentially increase productivity. This paper presents a model of massively distributed collaborative authorship of academic papers. This model, developed by a collective of thirty authors, identifies key tools and techniques that would be necessary or useful to the writing process. The process of collaboratively writing this paper was used to discover, negotiate, and document issues in massively authored scholarship. Our work provides the first extensive discussion of the experiential aspects of large-scale collaborative research.	0	0

Omnipedia: Bridging the Wikipedia Language Gap	Patti Bao Brent Hecht Samuel Carton Mahmood Quaderi Michael Horn Darren Gergle	Wikipedia Multilingual Hyperlingual Language barrier User generated content Text mining	International Conference on Human Factors in Computing Systems	English	2012	We present Omnipedia, a system that allows Wikipedia readers to gain insight from up to 25 language editions ofWikipedia simultaneously. Omnipedia highlights the similarities and differences that exist among Wikipedia language editions, and makes salient information that is unique to each language as well as that which is shared more widely. We detail solutions to numerous front-end and algorithmic challenges inherent to providing users with a multilingual Wikipedia experience. These include visualizing content in a language-neutral way and aligning data in the face of diverse information organization strategies. We present a study of Omnipedia that characterizes how people interact with information using a multilingual lens. We found that users actively sought information exclusive to unfamiliar language editions and strategically compared how language editions defined concepts. Finally, we briefly discuss how Omnipedia generalizes to other domains facing language barriers.	0	0
On the Evolution of Quality Flaws and the Effectiveness of Cleanup Tags in the English Wikipedia	Maik Anderka Benno Stein Matthias Busse	Wikipedia Cleanup Tags Quality Flaws Information quality Quality Flaw Evolution	Wikipedia Academy	English	2012	The improvement of information quality is a major task for the free online encyclopedia Wikipedia. Recent studies targeted the analysis and detection of specific quality flaws in Wikipedia articles. To date, quality flaws have been exclusively investigated in current Wikipedia articles, based on a snapshot representing the state of Wikipedia at a certain time. This paper goes further, and provides the first comprehensive breakdown of the evolution of quality flaws in Wikipedia. We utilize cleanup tags to analyze the quality flaws that have been tagged by the Wikipedia community in the English Wikipedia, from its launch in 2001 until 2011. This leads to interesting findings regarding (1) the development of Wikipedia's quality flaw structure and (1) the usage and the effectiveness of cleanup tags. Specifically, we show that inline tags are more effective than tag boxes, and provide statistics about the considerable volume of rare and non-specific cleanup tags. We expect that this work will support the Wikipedia community in making quality assurance activities more efficient.	0	0
On the Use of PU Learning for Quality Flaw Prediction in Wikipedia	Edgardo Ferretti Donato Hernández Fusilier Rafael Guzmán Cabrera Manuel Montes y Gómez Marcelo Errecalde Paolo Rosso		PAN	English	2012	In this article we describe a new approach to assess Quality Flaw Prediction in Wikipedia. The partially supervised method studied, called PU Learning, has been successfully applied in classifications tasks with traditional corpora like Reuters-21578 or 20-Newsgroups. To the best of our knowledge, this is the first time that it is applied in this domain. Throughout this paper, we describe how the original PU Learning approach was evaluated for assessing quality flaws and the modifications introduced to get a quality flaws predictor which obtained the best F1 scores in the task “Quality Flaw Prediction in Wikipedia” of the PAN challenge.	0	0

Predicting Quality Flaws in User-generated Content: The Case of Wikipedia	Maik Anderka Benno Stein Nedim Lipka	User-generated Content Analysis Information quality Wikipedia Quality Flaw Prediction One-class Classification	35th International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR 2012)	English	2012	The detection and improvement of low-quality information is a key concern in Web applications that are based on user-generated content; a popular example is the online encyclopedia Wikipedia. Existing research on quality assessment of user-generated content deals with the classification as to whether the content is high-quality or low-quality. This paper goes one step further: it targets the prediction of quality flaws, this way providing specific indications in which respects low-quality content needs improvement. The prediction is based on user-defined cleanup tags, which are commonly used in many Web applications to tag content that has some shortcomings. We apply this approach to the English Wikipedia, which is the largest and most popular user-generated knowledge source on the Web. We present an automatic mining approach to identify the existing cleanup tags, which provides us with a training corpus of labeled Wikipedia articles. We argue that common binary or multiclass classification approaches are ineffective for the prediction of quality flaws and hence cast quality flaw prediction as a one-class classification problem. We develop a quality flaw model and employ a dedicated machine learning approach to predict Wikipedia's most important quality flaws. Since in the Wikipedia setting the acquisition of significant test data is intricate, we analyze the effects of a biased sample selection. In this regard we illustrate the classifier effectiveness as a function of the flaw distribution in order to cope with the unknown (real-world) flaw-specific class imbalances. The flaw prediction performance is evaluated with 10,000 Wikipedia articles that have been tagged with the ten most frequent quality flaws: provided test data with little noise, four flaws can be detected with a precision close to 1.	0	0

The Gene Wiki in 2011: community intelligence applied to human gene annotation	Benjamin M. Good Erik L. Clarke Luca de Alfaro Andrew I. Su		Nucleic Acids Research	English	2012	The Gene Wiki is an open-access and openly editable collection of Wikipedia articles about human genes. Initiated in 2008, it has grown to include articles about more than 10 000 genes that, collectively, contain more than 1.4 million words of gene-centric text with extensive citations back to the primary scientific literature. This growing body of useful, gene-centric content is the result of the work of thousands of individuals throughout the scientific community. Here, we describe recent improvements to the automated system that keeps the structured data presented on Gene Wiki articles in sync with the data from trusted primary databases. We also describe the expanding contents, editors and users of the Gene Wiki. Finally, we introduce a new automated system, called WikiTrust, which can effectively compute the quality of Wikipedia articles, including Gene Wiki articles, at the word level. All articles in the Gene Wiki can be freely accessed and edited at Wikipedia, and additional links and information can be found at the project's Wikipedia portal page: http://en.wikipedia.org/wiki/Portal:Gene_Wiki.	0	0
The SEQanswers wiki: a wiki database of tools for high-throughput sequencing analysis	Jing-Woei Li Keith Robison Marcel Martin Andreas Sjödin Björn Usadel Matthew Young Eric C. Olivares Dan M. Bolser			English	2012	Recent advances in sequencing technology have created unprecedented opportunities for biological research. However, the increasing throughput of these technologies has created many challenges for data management and analysis. As the demand for sophisticated analyses increases, the development time of software and algorithms is outpacing the speed of traditional publication. As technologies continue to be developed, methods change rapidly, making publications less relevant for users. The SEQanswers wiki (SEQwiki) is a wiki database that is actively edited and updated by the members of the SEQanswers community (http://SEQanswers.com/). The wiki provides an extensive catalogue of tools, technologies and tutorials for high-throughput sequencing (HTS), including information about HTS service providers. It has been implemented in MediaWiki with the Semantic MediaWiki and Semantic Forms extensions to collect structured data, providing powerful navigation and reporting features. Within 2 years, the community has created pages for over 500 tools, with approximately 400 literature references and 600 web links. This collaborative effort has made SEQwiki the most comprehensive database of HTS tools anywhere on the web. The wiki includes task-focused mini-reviews of commonly used tools, and a growing collection of more than 100 HTS service providers. SEQwiki is available at: http://wiki.SEQanswers.com/.	0	0

Its rapid success has inspired hundreds of scholars from various disciplines to study its content, communication and community dynamics from various perspectives. This article presents a systematic review of scholarly research on Wikipedia. We describe our detailed, rigorous methodology for identifying over 450 scholarly studies of Wikipedia. We present the WikiLit website (http wikilit dot referata dot com), where most of the papers reviewed here are described in detail. In the major section of this article, we then categorize and summarize the studies. An appendix features an extensive list of resources useful for Wikipedia researchers.	15	0
There is No Deadline - Time Evolution of Wikipedia Discussions	Andreas Kaltenbrunner David Laniado	Wikipedia Online discussion Temporal patterns H-index	WikiSym	English	2012	Wikipedia articles are by definition never finished: at any moment their content can be edited, or discussed in the associated talk pages. In this study we analyse the evolution of these discussions to unveil patterns of collective participation along the temporal dimension, and to shed light on the process of content creation on different topics. At a micro-scale, we investigate peaks in the discussion activity and we observe a non-trivial relationship with edit activity. At a larger scale, we introduce a measure to account for how fast discussions grow in complexity, and we find speeds that span three orders of magnitude for different articles. Our analysis should help the community in tasks such as early detection of controversies and assessment of discussion maturity.	0	0
WIKISCORE - A Collaborative Environment For Music Transcription And Publishing	José João A. G. Dias de Almeida Nuno Ramos Carvalho José Nuno Oliveira	Music transcription ABC Wiki Collaborative work Music publishing	Social Shaping of Digital Publishing: Exploring the Interplay Between Culture and Technology - Proceedings of the 16th International Conference on Electronic Publishing	English	2012	Music sources are most commontly shared in music scores scanned or printed on paper sheets. These artifacts are rich in information, but since they are images it is hard to re-use and share their content in todays' digital world. There are modern languages that can be used to transcribe music sheets, this is still a time consuming task, because of the complexity involved in the process and the typical huge size of the original documents. WIKI SCORE is a collaborative environment where several people work together to transcribe music sheets to a shared medium, using the notation. This eases the process of transcribing huge documents, and stores the document in a well known notation, that can be used later on to publish the whole content in several formats, such as a PDF document, images or audio files for example.	2	0
Wikidata: a new platform for collaborative data collection	Denny Vrandečić	Semantic web Wikipedia Linked data DBpedia	International conference companion on World Wide Web	English	2012	This year, Wikimedia starts to build a new platform for the collaborative acquisition and maintenance of structured data: Wikidata. Wikidata's prime purpose is to be used within the other Wikimedia projects, like Wikipedia, to provide well-maintained, high-quality data. The nature and requirements of the Wikimedia projects require to develop a few novel, or at least unusual features for Wikidata: Wikidata will be a secondary database, i.e. instead of containing facts it will contain references for facts. It will be fully internationalized. It will contain inconsistent and contradictory facts, in order to represent the diversity of knowledge about a given entity.	0	0
Wikipedia Lover, Not a Hater: Harnessing Wikipedia to Increase the Discoverability of Library Resources	Danielle Elder R. Niccole Westbrook Michele Reilly	Wikipedia Wikimedia Commons School of Library Information Science internship programs Digital collections Web referral Web traffic Marketing Collection promotion	Journal of Web Librarianship	English	2012	During the spring of 2010, the University of Houston Libraries Digital Services Department began an initiative to promote existing and upcoming collections in the University of Houston Digital Library and drive traffic to the online repository. Spurred by an OCLC report (De Rosa et al. 2005) that only two percent of college and university students began research by consulting library resources, University of Houston Digital Services staff sought to add content from the University of Houston Digital Library to Wikipedia in order to insert primary source digital materials into the research workflow of students and faculty. As a result, referrals from Wikipedia to the University of Houston Digital Library have increased significantly and the pilot project is now the basis for an ongoing University of Houston Digital Services program. The structure and direction of the pilot project were a collaborative effort between University of Houston Digital Services staff and a University of North Texas Library and Information Science intern participating in the University of Houston Digital Services Digital Library Internship Program. Through this case study the authors cover the evolution of the University of Houston Digital Services Wikipedia pilot project and its growth into a permanent program. The authors also outline the workflows and procedures of the project and describes in detail the challenges and successes of the pilot Wikipedia project at University of Houston Digital Services. Included are lessons learned for libraries and cultural institutions interested in establishing a similar program.	0	1
Wikis en docencia: una experiencia con WikiHaskell y StatMediaWiki (RUSC)	Manuel Palomo-Duarte Inmaculada Medina-Bulo Emilio J. Rodríguez-Posada Francisco Palomo-Lozano	Computer-supported collaborative learning Wiki Medición en aprendizaje electrónico Libre software	Revista de Universidad y Sociedad del Conocimiento	Spanish English	2012	En este artículo se presenta WikiHaskell, un proyecto basado en tecnologías wiki que se ha desarrollado en la titulación de Ingeniero en Informática de la Universidad de Cádiz. WikiHaskell es un wiki en el que los alumnos, organizados en grupos de tres, crean material complementario sobre bibliotecas del lenguaje de programación Haskell. El principal objetivo de este proyecto es incorporar al aula la creación de conocimiento libre, de manera que se consiga que los alumnos se conviertan en los verdaderos protagonistas de la asignatura. Para evaluar el wiki y, por tanto, el trabajo realizado por el alumnado se ha desarrollado StatMediaWiki, un sistema de análisis estadístico para wikis MediaWiki que permite hacerlo de manera sencilla y transparente. StatMediaWiki genera un informe general del wiki y análisis individuales del trabajo desarrollado por cada usuario, por cada página y por cada categoría. Gracias al análisis de contribuciones de esta herramienta se han podido identificar varios perfiles de usuario según su distribución temporal en el curso. Del mismo modo, el análisis por categorías facilita la detección de determinadas situaciones dentro de un grupo, como por ejemplo, la ubicación de los alumnos líderes o la de los menos activos. Tanto el contenido del wiki como el código de StatMediaWiki son libres y accesibles públicamente.	16	0
Creative Commons licenses and the non-commercial condition	Daniel Mietchen Robert A. Morris Donat Agosti Lyubomir Penev Walter G. Berendsohn Donald Hobern		ZooKeys	English	28 November 2011	The Creative Commons (CC) licenses are a suite of copyright-based licenses defining terms for the distribution and re-use of creative works. CC provides licenses for different use cases and includes open content licenses such as the Attribution license (CC BY, used by many Open Access scientific publishers) and the Attribution Share Alike license (CC BY-SA, used by Wikipedia, for example). However, the license suite also contains non-free and non-open licenses like those containing a “non-commercial” (NC) condition. Although many people identify “non-commercial” with “non-profit”, detailed analysis reveals that significant differences exist and that the license may impose some unexpected re-use limitations on works thus licensed. After providing background information on the concepts of Creative Commons licenses in general, this contribution focuses on the NC condition, its advantages, disadvantages and appropriate scope. Specifically, it contributes material towards a risk analysis for potential re-users of NC-licensed works.	0	0

Autonomous Link Spam Detection in Purely Collaborative Environments	Andrew G. West Avantika Agrawal Phillip Baker Brittney Exline Insup Lee	Wikipedia Collaboration Collaborative security Information security Spam Spam mitigation Reputation Spatio- temporal features Machine learning Intelligent routing	WikiSym	English	October 2011	Collaborative models (e.g., wikis) are an increasingly prevalent Web technology. However, the open-access that defines such systems can also be utilized for nefarious purposes. In particular, this paper examines the use of collaborative functionality to add inappropriate hyperlinks to destinations outside the host environment (i.e., link spam). The collaborative encyclopedia, Wikipedia, is the basis for our analysis. Recent research has exposed vulnerabilities in Wikipedia's link spam mitigation, finding that human editors are latent and dwindling in quantity. To this end, we propose and develop an autonomous classifier for link additions. Such a system presents unique challenges. For example, low barriers-to-entry invite a diversity of spam types, not just those with economic motivations. Moreover, issues can arise with how a link is presented (regardless of the destination). In this work, a spam corpus is extracted from over 235,000 link additions to English Wikipedia. From this, 40+ features are codified and analyzed. These indicators are computed using "wiki" metadata, landing site analysis, and external data sources. The resulting classifier attains 64% recall at 0.5% false-positives (ROC-AUC=0.97). Such performance could enable egregious link additions to be blocked automatically with low false-positive rates, while prioritizing the remainder for human inspection. Finally, a live Wikipedia implementation of the technique has been developed.	0	0
What Wikipedia Deletes: Characterizing Dangerous Collaborative Content	Andrew G. West Insup Lee	Wikipedia User generated content Collaboration Redaction Content removal Copyright Information security	WikiSym	English	October 2011	Collaborative environments, such as Wikipedia, often have low barriers-to-entry in order to encourage participation. This accessibility is frequently abused (e.g., vandalism and spam). However, certain inappropriate behaviors are more threatening than others. In this work, we study contributions which are not simply ``undone -- but *deleted* from revision histories and public view. Such treatment is generally reserved for edits which: (1) present a legal liability to the host (e.g., copyright issues, defamation), or (2) present privacy threats to individuals (i.e., contact information). Herein, we analyze one year of Wikipedia's public deletion log and use brute-force strategies to learn about privately handled redactions. This permits insight about the prevalence of deletion, the reasons that induce it, and the extent of end-user exposure to dangerous content. While Wikipedia's approach is generally quite reactive, we find that copyright issues prove most problematic of those behaviors studied.	0	0

Link Spamming Wikipedia for Profit	Andrew G. West Jian Chang Krishna Venkatasubramanian Oleg Sokolsky Insup Lee	Web 2.0 spam Spam Wikipedia Wiki Collaborative security Attack model Measurement study Spam economics	CEAS '11: Proc. of the 8th Annual Collaboration, Electronic Messaging, Anti-Abuse, and Spam Conference	English	September 2011	Collaborative functionality is an increasingly prevalent web technology. To encourage participation, these systems usually have low barriers-to-entry and permissive privileges. Unsurprisingly, ill-intentioned users try to leverage these characteristics for nefarious purposes. In this work, a particular abuse is examined -- link spamming -- the addition of promotional or otherwise inappropriate hyperlinks. Our analysis focuses on the wiki model and the collaborative encyclopedia, Wikipedia, in particular. A principal goal of spammers is to maximize *exposure*, the quantity of people who view a link. Creating and analyzing the first Wikipedia link spam corpus, we find that existing spam strategies perform quite poorly in this regard. The status quo spamming model relies on link persistence to accumulate exposures, a strategy that fails given the diligence of the Wikipedia community. Instead, we propose a model that exploits the latency inherent in human anti-spam enforcement. Statistical estimation suggests our novel model would produce significantly more link exposures than status quo techniques. More critically, the strategy could prove economically viable for perpetrators, incentivizing its exploitation. To this end, we address mitigation strategies.	0	0
Multilingual Vandalism Detection using Language-Independent & Ex Post Facto Evidence	Andrew G. West Insup Lee		PAN-CLEF	English	September 2011	There is much literature on Wikipedia vandalism detection. However, this writing addresses two facets given little treatment to date. First, prior efforts emphasize zero-delay detection, classifying edits the moment they are made. If classification can be delayed (e.g., compiling offline distributions), it is possible to leverage ex post facto evidence. This work describes/evaluates several features of this type, which we find to be overwhelmingly strong vandalism indicators. Second, English Wikipedia has been the primary test-bed for research. Yet, Wikipedia has 200+ language editions and use of localized features impairs portability. This work implements an extensive set of language-independent indicators and evaluates them using three corpora (German, English, Spanish). The work then extends to include language-specific signals. Quantifying their performance benefit, we find that such features can moderately increase classifier accuracy, but significant effort and language fluency are required to capture this utility. Aside from these novel aspects, this effort also broadly addresses the task, implementing 65 total features. Evaluation produces 0.840 PR-AUC on thezero-delay task and 0.906 PR-AUC with ex post facto evidence (averaging languages). Performance matches the state-of-the-art (English), sets novel baselines (German, Spanish), and is validated by a first-place finish over the 2011 PAN-CLEF test set.	0	0
Processos editoriais auto-organizados na Wikipédia em português: a edição colaborativa de "Biografias de Pessoas Vivas"	Carlos Frederico de Brito d’Andréa	Wikipedia Edition Rewritting Colaboration Self-organization Complexity		Portuguese	September 2011	This dissertation maps and analyzes the dynamics of editions in a sample of articles of the Portuguese version of Wikipedia. We identify and discuss the self-organized and collaborative processes in its editorial network, as well as how the editors rewrite the articles over time. This research begins with conceptual considerations about the “encyclopedia that anyone can edit”, focusing on trends of the Portuguese version and specifically on the “Biographies of Living People”, which are characterized by the possibility of including, “in real time”, factual information about the life and work of influent people. The theoretical framework is composed by authors from different areas. In Text Linguistics, we discuss the concepts of text (BEAUGRANDE, 1997; COSCARELLI, 2006), textuality (COSTA VAL, 2004), retextualization and rewritting (DELL’ISOLA, 2007; MARCUSCHI, 2000; MATENCIO, 2002). Besides that, we discuss the editorial processes and professional activities (like copy editing) in the “production networks” of books and encyclopedias, especially after the use of digital technologies. In chapter 3, we discuss the networked editorial production based on the internet and inspired in “hacker culture” and “open source softwares”. In this context, the most important concepts are “commonbased peer production” (BENKLER, 2006), “The Wisdom of Crowds” (SUROWIECKI, 2007), “produsage” (BRUNS, 2008), “virtual community” e “crowdsourcing” (HAYTHORNTHWAITE, 2009). We also present the relationships between this new model and traditional editorial processes, like “networked book” and “wiki-journalism”. After that, we relate networked editorial production with complexity paradigm and discuss Wikipedia as a complex adaptive system (HOLLAND, 1995; LARSEN-FREEMAN e CAMERON, 2008) that, potentially, works in a self-organized and emergent dynamics (DEBRUN, 1996a, 1996b; DE WOLF e HOLVOET, 2005). The empirical study of this thesis is based in 91 “Biographies of Living People” about most influential Brazilian personalities in the year of 2009 according two national magazines (“Época” and “Isto É”). In the quantitative phase of this work, we extracted data in articles history pages using a software (WikipediAnalyserPT) developed for this research. After making statistical analyses, we compared the edition processes of these articles using variables as “total of editions”, “editions made by groups of editors” (registered, non-registered, administrators and bots), “protections”, “reversions” etc. At the qualitative stage, we detail the dynamics of edition of five of articles and analyze the rewrittings of the texts and the interactions between the editors. Three articles were chosen because the “key variables” are very similar: the biographies of “Franklin Martins” (a journalist that worked in president Lula's government), “Kátia Abreu” (a senator known for defending owners of very large land areas) and “Ricardo Teixeira” (a president of the Brazilian Football Confederation). After that, we analyze the dynamics of two of the most edited articles of the sample: the biographies about the famous soccer players "Adriano Leite Ribeiro" (nicknamed "The Emperor") and "Ronaldo Nazario of Lima (also known as "The Phenomenon"). In the three intermediate articles, we identified a relative stability (caused by a few number of editions monthly) interspersed with short periods of time with more editions and disputes. We also observed that a few editors made almost all the “important” editions. In the two more edited biographies, we noticed an uninterrupted movement of the editors, hundreds of vandalisms and many war editions. Although also in these articles only a few editions are preserved, we identify an “emergence” pattern characterized by disputes that encourage the collaboration among agents. At the conclusion, we discuss the possibilities and challenges of a “wikification” of editorial processes.	60	0

Analyzing the wikisphere: Methodology and data to support quantitative wiki research	Jeffrey Stuckman James Purtilo		Journal of the American Society for Information Science and Technology	English	August 2011	Owing to the inherent difficulty in obtaining experimental data from wikis, past quantitative wiki research has largely focused on Wikipedia, limiting the ability to generalize such research. To facilitate the analysis of wikis other than Wikipedia, we developed WikiCrawler, a tool that automatically gathers research data from public wikis without supervision. We then built a corpus of 151 wikis, which we have made publicly available. Our analysis indicated that these wikis display signs of collaborative authorship, validating them as objects of study. We then performed an initial analysis of the corpus and discovered some similarities with Wikipedia, such as users contributing at unequal rates. We also analyzed distributions of edits across pages and users, resulting in data which can motivate or verify mathematical models of behavior on wikis. By providing data collection tools and a corpus of already-collected data, we have completed an important first step for investigations that analyze user behavior, establish measurement baselines for wiki evaluation, and generalize Wikipedia research by testing hypotheses across many wikis.	0	0
Design Mechanisms for MediaWiki to Support Collaborative Writing in a Mandatory Context	Sumonta Kasemvilas	Design Information technology Educational technology		English	August 2011	Because MediaWiki is not appropriate for use in the classroom setting due to its decentralization, arbitrariness, and sharing, its flexible characteristics complicate concepts of practical design when applying MediaWiki in a mandatory writing context. This dissertation identifies a need to add extensions to facilitate increased accountability, project management, discussion, and awareness based on a theoretical framework, proposes MediaWiki with some modifications as an innovative way to optimize the strengths associated with constructivist learning and social presence, and examines the results of those changes. Relevant theoretical perspectives are used to contextualize the potential significance of additional extensions of MediaWiki. Three categories of mechanisms in MediaWiki—role, awareness, and project management—were newly developed in this research. They are designed to increase project control and accountability. Discussion, chat, text editor, and online notification extensions were also installed and customized to meet the needs of the students. Two case studies were conducted in two separate graduate classes to test the value of the extensions. Quantitative and qualitative data were collected and analyzed. Use of qualitative methods helps add texture to quantitative findings. The findings illustrate some potential impact for classroom use. Delineation of the results in Case Study 1 and Case Study 2 provides well-grounded rationale for why the proposed new MediaWiki mechanisms positively impact collaborative writing. By applying a set of extended features to MediaWiki, some problems were solved and others were mitigated, but other problems were not resolved and new problems emerged. Thus, this study articulates the benefits and the additional problems using MediaWiki and extensions and suggests ways to improve the group writing process. Using MediaWiki in academia needs appropriate governance and proper technology. The results potentially offer new teaching mechanisms for graduate students involved with collaborative writing. The study holds promise in improving collaborative efforts in mandatory group writing projects and discusses a way to facilitate collaborative writing in this context. Implications of this study can assist researchers and developers in understanding what effects the extensions have on users.	26	0

This process occurs from cognitive and pragmatic sanctions given to themes and figures that make up the thematic isotopy of users enunciation. The identification of these elements in this dissertation, was carried out by Greimas' semiotics. Sanctions should pragmatically represent the guidelines of the collaborative process on Wikipedia, but there are institutionalized rules that are presented to users as the five pillars of Wikipedia. The five pillars are about the encyclopedism, neutral point of view, free license, community conviviality and liberality in the rules. The statute assigns values to the practice of encyclopedias and information that are published by them. These values were defined by tensive semiotics and compared with the cognitive and pragmatic sanctions of the isotopies enunciated by users, to check the consistency between what is being requested by Wikipedia and what is being done by their contributors. The results of this comparison show some similarities and differences between discourse and practice, indicating ownership of Wikipedia by its users and the need for more accuracy and criteria in conflicting issues or controversies for the permanence of information on the page entry. The verifiability of the information was presented as a greatly appreciated theme by users, indicating the importance of the veracity of reference sources and the verification of information. The freedoms and distribution of powers introduced by the principles are denied on the practice of editing. Wikipedia presented itself as a very liberal and tolerant encyclopedia, giving substance to the collaboration, but, in practice, very restrictive and careful when it comes to the permanence of a content in the article page.	4	1
Exploring students’ perceptions of integrating Wiki technology and peer feedback into English writing courses	Wen-Chuan Lin Shu Ching Yang	Collaborative writing Peer review Wiki	English Teaching: Practice and Critique	English	July 2011	This study applied Wiki technology and peer review to an English as a foreign language writing class. The objective was to investigate whether this system, as a collaborative platform, would improve students writing skills. The study gauged students’ perceptions about integrating a Wiki writing course and peer feedback. The participants were 32 sophomore students in an English department at a college in Taiwan. The study used a socio-cultural theoretical framework to explore students’ perceptions of the effectiveness of Wiki-based writing projects and experiences of social interaction in the process of writing, based on self-reported reflections about the project, observations of student learning, interviews and surveys. Findings revealed that most students explicitly stated that they felt positive about their ability to apply Wiki and peer feedback to writing instruction. Meaningful social interaction appears to play a significant role with regard to students’ perceived benefits of this collaborative writing process. Students nevertheless encountered both functional and psychological obstacles to using the new tools, indicating the need to alter their traditional learning practices to embrace new, technology-enhanced learning systems.	9	0
Factual accuracy and trust in information: The role of expertise	Teun Lucassen Jan Maarten Schraagen		Journal of the American Society for Information Science and Technology	English	July 2011	In the past few decades, the task of judging the credibility of information has shifted from trained professionals (e.g., editors) to end users of information (e.g., casual Internet users). Lacking training in this task, it is highly relevant to research the behavior of these end users. In this article, we propose a new model of trust in information, in which trust judgments are dependent on three user characteristics: source experience, domain expertise, and information skills. Applying any of these three characteristics leads to different features of the information being used in trust judgments; namely source, semantic, and surface features (hence, the name 3S-model). An online experiment was performed to validate the 3S-model. In this experiment, Wikipedia articles of varying accuracy (semantic feature) were presented to Internet users. Trust judgments of domain experts on these articles were largely influenced by accuracy whereas trust judgments of novices remained mostly unchanged. Moreover, despite the influence of accuracy, the percentage of trusting participants, both experts and novices, was high in all conditions. Along with the rationales provided for such trust judgments, the outcome of the experiment largely supports the 3S-model, which can serve as a framework for future research on trust in information.	0	0
Wiki Readers Wiki Writers	Thomas W. Reynolds Jr	Communication Web studies Rhetoric		English	July 2011	In 1995, the first wiki website, Ward Cunningham's Wiki WikiWeb, went public for the use of a community of computer programmers, and few outside of that community and those working in similar fields would have imagined wiki technology, a technology that allows visitors to a wiki-based web site to modify its structure and content. Fifteen years later, however, wiki comes to compositionists an already-loaded term. The mainstream media depicts wiki as a challenge to the ways we think about who writes and disseminates information, the nature of information itself, and who reads and how they read and use that information. At the same time, scholarship in the field of composition studies claims wiki as a writing tool that evidences and provides the process-centered, collaborative, democratized space for which researchers and teachers of writing have been looking. In both cases, the literature constructs ideas about what it means to be a writer and a reader in relation to wiki so that compositionists encounter wiki technology as always already described and defined. I analyze these oppositional perspectives on wiki technology and make it possible to move through, before, and beyond these constructions of readers and writers and the intellectual traditions through which they are made possible to make space for other readings of wiki technology and answer the following questions: How are the traditional roles of reader and writer articulated or challenged in the discourse surrounding wiki technology? How are the roles of readers and writers made possible through applications of wiki technology? I analyze the discourse surrounding wiki technology and then the writer and reader functions made possible in three wiki applications: Wikipedia, Scholarpedia, and Citizendium. It is the argument of this project that wiki makes visible and explicit the ways in which readers and writers have always already interacted, or at least desired to interact, providing a deeper and different understanding of the roles assumed by and constructed for readers and writers, an understanding that is situated within, without, and in the margins of the traditions that have always already constructed them (and wiki technology) differently.	32	0

An Introductory Historical Contextualization of Online Creation Communities for the Building of Digital Commons: The Emergence of a Free Culture Movement	Mayo Fuster Morell		Proceedings of the 6th Open Knowledge Conference	English	June 2011	Online Creation Communities (OCCs) are a set of individuals that communicate, interact and collaborate; in several forms and degrees of participation which are eco-systemically integrated; mainly via a platform of participation on the Internet, on which they depend; and aiming at knowledge-making and sharing. The paper will first provide an historical contextualization OCCs. Then, it will show how the development of OCCs is fuelled by and contributes to, the rise of a free culture movement defending and advocating the creation of digital commons, and provide an empirically grounded definition of free culture movement. The empirical analyses is based content analysis of 80 interviews to free culture practitioners, promoters and activists with an international background or rooted in Europe, USA and Latino-America and the content analysis of two seminar discussions. The data collection was developed from 2008 to 2010.	0	0

Towards a diversity-minded Wikipedia	Fabian Flöck Denny Vrandečić Elena Simperl	Wikipedia Diversity Community-driven content creation Social dynamics Opinion mining Sentiment analysis	WebSci Conference	English	June 2011	Wikipedia is a top-ten Web site providing a free encyclopedia created by an open community of volunteer contributors. As investigated in various studies over the past years, contributors have different backgrounds, mindsets and biases; however, the effects - positive and negative - of this diversity on the quality of the Wikipedia content, and on the sustainability of the overall project are yet only partially understood. In this paper we discuss these effects through an analysis of existing scholarly literature in the area and identify directions for future research and development; we also present an approach for diversity-minded content management within Wikipedia that combines techniques from semantic technologies, data and text mining and quantitative social dynamics analysis to create greater awareness of diversity-related issues within theWikipedia community, give readers access to indicators and metrics to understand biases and their impact on the quality of Wikipedia articles, and support editors in achieving balanced versions of these articles that leverage the wealth of knowledge and perspectives inherent to large-scale collaboration.	24	1

Evaluating WikiTrust: A trust support tool for Wikipedia	Teun Lucassen Jan Maarten Schraagen		First Monday	English	May 2011	Because of the open character of Wikipedia readers should always be aware of the possibility of false information. WikiTrust aims at helping readers to judge the trustworthiness of articles by coloring the background of less trustworthy words in a shade of orange. In this study we look into the effects of such coloring on reading behavior and trust evaluation by means of an eye–tracking experiment. The results show that readers had more difficulties reading the articles with coloring than without coloring. Trust in heavily colored articles was lower. The main concern is that the participants in our experiment rated usefulness of WikiTrust low.	7	0
Hackers, Cyborgs, and Wikipedians: The Political Economy and Cultural History of Wikipedia	Andrew A. Famiglietti	Wikipedia Peer Production Cultural Studies New Media Political Economy		English	May 2011	This dissertation explores the political economy and cultural history of Wikipedia, the free encyclopedia. It demonstrates how Wikipedia, an influential and popular site of knowledge production and distribution, was influenced by its heritage from the hacker communities of the late twentieth century. More specifically, Wikipedia was shaped by an ideal I call, “the cyborg individual,” which held that the production of knowledge was best entrusted to a widely distributed network of individual human subjects and individually owned computers. I trace how this ideal emerged from hacker culture in response to anxieties hackers experienced due to their intimate relationships with machines. I go on to demonstrate how this ideal influenced how Wikipedia was understood both those involved in the early history of the site, and those writing about it. In particular, legal scholar Yochai Benkler seems to base his understanding of Wikipedia and its strengths on the cyborg individual ideal. Having established this, I then move on to show how the cyborg individual ideal misunderstands Wikipedia's actual method of production. Most importantly, it overlooks the importance of how the boundaries drawn around communities and shared technological resources shape Wikipedia's content. I then proceed to begin the process of building what I believe is a better way of understanding Wikipedia, by tracing how communities and shared resources shape the production of recent Wikipedia articles.	70	0
La dimensió de les llengües a la Wikipedia i la seua relació amb els elements socials	Borja Pellejero Natxo Sorolla Marina Nogué	Wikipedia Digital language community Catalan CRUSCAT IEC	Digithum	Catalan	May 2011	There would seem to be a contradiction in the fact that Catalan should have a Wikipedia with a similar number of pages to that in Chinese. There are fewer than ten million Catalan speakers, and they were marginalised in their own land for a long time, but they have still been able to produce content on the internet that in some cases matches that of China, a world economic superpower with nearly one billion Chinese speakers. Though it should be noted that the situation is not the same in China as it is in those places where Catalan is spoken. This article offers an initial look at the social, educational, technological, economic and demographic factors linked to a language’s position in the ranking of number of Wikipedia articles. This analysis is based on one key concept, that of the digital language community, and the observation that Catalan’s position on the internet is not due to the activism of its speakers, but to a position that resembles that of any other medium-sized language community. Hi ha un aparent contrasentit en el fet que el català tinga a la Wikipedia un nombre d’articles similar al xinès. Una comunitat que no arriba a deu milions de catalanoparlants, llargament minoritzada al propi territori, pot arribar a tenir una capacitat de producció a internet que en alguns casos és assimilable a la de la Xina, que, amb prop de mil milions de parlants de xinès, és una superpotència econòmica mundial. Els més àvids matisaran que la situació no és la mateixa a la Xina que als territoris de llengua catalana. Aquest text vol fer una primera aproximació a quins són aquests factors socials, educatius, tecnològics, econòmics i demogràfics que estan relacionats amb la posició d’una llengua en el rànquing del nombre d’articles a la Wikipedia. D’aquesta anàlisi naix un concepte clau, el de la comunitat lingüística digital, i l’observació que la posició del català en el món d’internet no es deu a un pretès activisme dels seus parlants, sinó més aviat a una posició força semblant a la d’altres comunitats lingüístiques de demografia mitjana.	8	0
Sustainable multilingual communication: Managing multilingual content using free and open source content management systems	Todd Kelsey			English	May 2011	It is often too complicated or expensive for most educators, non-profits and individuals to create and maintain a multilingual Web site, because of the technological hurdles, and the logistics of working with content in different languages. But multilingual content management systems, combined with streamlined processes and inexpensive organizational tools, make it possible for educators, non-profit entities and individuals with limited resources to develop sustainable and accessible multilingual Web sites. The research included a review of what's been done in the theory and practice of designing Web sites for multilingual audiences. On the basis of that review, a series of sustainable multilingual Web sites were created, and a series of approaches and systems were tested, including MediaWiki, Plone, Drupal, Joomla, PHPMyFAQ, Blogger, Google Docs and Google Sites. There was also a case study on "Social CMS", which refers to emergent social networks such as Facebook. The case studies are reported on, and conclude with high-level recommendations that form a roadmap for sustainable multilingual Web site development. The basic conclusion is that Drupal is a recommended system for developing a multilingual Web site, based on a variety of factors. Google Sites is also a recommended system, based on the fact that it is free, easy to use, and very flexible.	9	0
Using wikis to experience history	Vance Scott Martin	Action research History education Technology in education Community college Wiki		English	May 2011	This dissertation is an action research study examining the use of technology to encourage critical thinking and digital literacy in a community college history class. The students are responsible for researching course material and teaching the class. They then use a wiki to contribute to and edit an interactive, online textbook that has been created by students over several semesters. The goal is to link more interactive technologies with what the author terms socially democratic education, by empowering students to create knowledge and encouraging them to consider biases in historical writing. Two main research questions are considered, each with related sub-questions. First, what do students experience using an educational wiki and an open classroom? Are the students able to think critically about history? The work of Giroux (1978) is used to discuss the critical thinking that emerged in the class. Second, what are the relationships between the wiki and open classroom, and democratic education? How is that observable? What role does the teacher play? Is this a critical pedagogy? Evidence of socially democratic learning is examined, and Freire (2009) is used to analyze the presence of a critical pedagogy. Several issues are raised as the result of the study, and their implications are discussed. These include the loss of teacher control with this type of pedagogy, the need for a balance between allowing freedom for discovery and organizational structure, and issues related to trust and identity.	3	0
A Technological Reinvention of the Textbook: A Wikibooks Project	Patrick M. O’Shea James C. Onderdonk Douglas Allen Dwight W. Allen	Pedagogy Technology Textbooks Wikibooks	Journal of Digital Learning in Teacher Education	English	April 2011	Education traditionally has been defined as a one-way relationship between teacher and learner. However, new technologies are dramatically changing that relationship in a multitude of ways. In this article, the authors describe some of these changes and explore one example of the intersection between technology and pedagogy, describing a college course in which students compose the course text using the wiki platform. The process described proceeds from the premise that the needs and capacity of learners in the information age have been transformed and discusses one way that using an appropriate technology may address them. For this wikibook, the creators of the content become the prime users of the content as well. The authors discuss both the philosophical underpinnings and practical implications of this approach. Evaluation of the project suggests that the methodology produces an active, credible learning process. This study explores the advantages and disadvantages of this wiki process to provide context concerning the efficacy and utility of employing particular types of Web 2.0 tools. The course development rationale points to its potential for radically changing how students and teachers interact with the phenomenon of ubiquitous learning.	2	0

A Characterization of Wikipedia Content Based on Motifs in the Edit Graph	Guangyu Wu Martin Harrigan Pádraig Cunningham		SMUC '11: Proceedings of the 3rd international workshop on Search and mining user-generated contents	English	February 2011	Good Wikipedia articles are authoritative sources due to the collaboration of a number of knowledgeable contributors. This is the many eyes idea. The edit network associated with a Wikipedia article can tell us something about its quality or authoritativeness. In this paper we explore the hypothesis that the characteristics of this edit network are predictive of the quality of the corresponding article's content. We characterize the edit network using a profile of network motifs and we show that this network motif profile is predictive of the Wikipedia quality classes assigned to articles by Wikipedia editors. We further show that the network motif profile can identify outlier articles particularly in the 'Featured Article' class, the highest Wikipedia quality class.	8	0
Wikipedia Vandalism Detection: Combining Natural Language, Metadata, and Reputation Features	B. Thomas Adler Luca de Alfaro Santiago M. Mola Velasco Paolo Rosso Andrew G. West	Wikipedia Wiki Collaboration Vandalism Machine learning Metadata Natural Language Processing Reputation	Lecture notes in computer science	English	February 2011	Wikipedia is an online encyclopedia which anyone can edit. While most edits are constructive, about 7% are acts of vandalism. Such behavior is characterized by modifications made in bad faith; introducing spam and other inappropriate content. In this work, we present the results of an effort to integrate three of the leading approaches to Wikipedia vandalism detection: a spatio-temporal analysis of metadata (STiki), a reputation-based system (WikiTrust), and natural language processing features. The performance of the resulting joint system improves the state-of-the-art from all previous methods and establishes a new baseline for Wikipedia vandalism detection. We examine in detail the contribution of the three approaches, both for the task of discovering fresh vandalism, and for the task of locating vandalism in the complete set of Wikipedia revisions.	0	1
959 Nematode Genomes: a semantic wiki for coordinating sequencing projects	Sujai Kumar Philipp H. Schiffer Mark Blaxter			English	2011	Genome sequencing has been democratized by second-generation technologies, and even small labs can sequence metazoan genomes now. In this article, we describe '959 Nematode Genomes'-a community-curated semantic wiki to coordinate the sequencing efforts of individual labs to collectively sequence 959 genomes spanning the phylum Nematoda. The main goal of the wiki is to track sequencing projects that have been proposed, are in progress, or have been completed. Wiki pages for species and strains are linked to pages for people and organizations, using machine- and human-readable metadata that users can query to see the status of their favourite worm. The site is based on the same platform that runs Wikipedia, with semantic extensions that allow the underlying taxonomy and data storage models to be maintained and updated with ease compared with a conventional database-driven web site. The wiki also provides a way to track and share preliminary data if those data are not polished enough to be submitted to the official sequence repositories. In just over a year, this wiki has already fostered new international collaborations and attracted newcomers to the enthusiastic community of nematode genomicists. www.nematodegenomes.org.	0	0

We have characterized the edition of the texts and the dynamics of interactions among the editors. Additionally, we have analyzed their contents according to three criteria: authority, verifiability and timeliness.	11	0
A lexicon for processing archaic language: the case of XIXth century Slovene	Tomaž Erjavec Christoph Ringlstetter Maja Žorga Annette Gotscharek		WoLeR 2011: International Workshop on Lexical Resources	English	2011	The paper presents a lexicon to support computational processing of historical Slovene texts. Historical Slovene texts are being increasingly digitised and made available on the internet but are still underutilised as no language technology support is offered for their processing. Appropriate tools and resources would enable full-text searching with modern-day lemmas, modernisation of archaic language to make it more accessible to today‟s readers, and automatic OCR correction. We discuss the lexicon needed to support tokenisation, modernisation, lemmatisation and part-of-speech tagging of historical texts. The process of lexicon acquisition relies on a proof-read corpus, a large lexicon of contemporary Slovene, and tools to map historical forms to their contemporary equivalents via a set of rewrite rules, and to provide an editing environment for lexicon construction. The lexicon, currently work in progress, will be made publicly available; it should help not only in making digital libraries more accessible but also provide a quantitative basis for linguistic explorations of historical Slovene texts and a prototype electronic dictionary of archaic Slovene.	1	0

A quantitative examination of the impact of featured articles in Wikipedia	Antonio J. Reinoso Jesús M. González-Barahona Rocío Muñoz Mansilla Israel Herraiz	Wikipedia Featured articles Usage patterns Traffic characterization Quantitative analysis	ICSOFT	English	2011	This paper presents a quantitative examination of the impact of the presentation of featured articles as quality content in the main page of several Wikipedia editions. Moreover, the paper also presents the analysis performed to determine the number of visits received by the articles promoted to the featured status. We have analyzed the visits not only in the month when articles awarded the promotion or were included in the main page, but also in the previous and following ones. The main aim for this is to assess the attention attracted by the featured content and the different dynamics exhibited by each community of users in respect to the promotion process. The main results of this paper are twofold: it shows how to extract relevant information related to the use of Wikipedia, which is an emerging research topic, and it analyzes whether the featured articles mechanism achieve to attract more attention.	3	0

The wiki format will always link to the fixed original journal description of the taxon, however it permits future edits and additions to species' taxonomy and biology. The diving beetle Neobidessodes darwiniensis sp. n. (Coleoptera: Dytiscidae, Bidessini) is described based on a single female, collected in a rest pool of the Harriet Creek in the Darwin Area, Northern Territory. Within Neobidessodes the new species is well characterized by its elongate oval body with rounded sides, short and stout segments of antennae, length of body and dorsal surface coloration. In addition to external morphology, we used mitochondrial cox1 sequence data to support generic assignment and to delineate the new species from other Australian Bidessini including all other known Neobidessodes. Illustrations based on digital images are provided here and as online resources. A modified key is provided. Altogether ten species of the genus are now known worldwide, nine from Australia and one from New Guinea.	0	1
AVBOT: Detecting and fixing vandalism in Wikipedia	Emilio J. Rodríguez-Posada	AVBOT Robot Libre software MediaWiki Monitoring Vandalism Wikipedia Wiki	UPGRADE	English	2011	Wikipedia is a project which aims to build a free encyclopaedia to spread the sum of all knowledge to every single human being. Today it can be said to be on the road to achieving that goal, having reached the 15 million articles milestone in 270 languages. Furthermore, if we include its sister projects (Wiktionary, Wikibooks, Wikisource,...), it has received more than 1 billion edits in 10 years and now has more than 10 billion page views every month. Compiling an encyclopaedia in a collaborative way has been possible thanks to MediaWiki software. It allows everybody to modify the content available on the site easily. But a problem emerges regarding this model: not all edits are made in good faith. AVBOT is a bot for protecting the Spanish Wikipedia against some undesired modifications known as vandalism. Although AVBOT was developed for Wikipedia, it can be used on any MediaWiki website. It is developed in Python and is free software. In the 2 years it has been in operation it has reverted more than 200,000 vandalism edits, while several clones have been executed, adding thousands of reverts to this count.	0	0

Characterizing Wikipedia pages using edit network motif profiles	Guangyu Wu Martin Harrigan Pádraig Cunningham	Authoritativeness Network motifs Wikipedia	SMUC	English	2011	Good Wikipedia articles are authoritative sources due to the collaboration of a number of knowledgeable contributors. This is the many eyes idea. The edit network associated with a Wikipedia article can tell us something about its quality or authoritativeness. In this paper we explore the hypothesis that the characteristics of this edit network are predictive of the quality of the corresponding article's content. We characterize the edit network using a profile of network motifs and we show that this network motif profile is predictive of the Wikipedia quality classes assigned to articles by Wikipedia editors. We further show that the network motif profile can identify outlier articles particularly in the 'Featured Article' class, the highest Wikipedia quality class.	0	0
Classification Techniques for Assessing Student Collaboration in Shared Wiki Spaces	Chitrabharathi Ganapathy Jeon-Hyung Kang Erin Shaw Jihie Kim			English	2011	This paper presents the case study of collaboration analysis in the context of an undergraduate student engineering project. Shared Wiki spaces used by students in collaborative project teams were analyzed and the paper presents new techniques, based on descriptive statistics and the Labeled Latent Dirichlet Allocation (LLDA) model for multi-label document classification, to assess quality of student work in shared wiki spaces. A link is shown between processes of collaboration, performance and work pace.	0	0

Co-authorship 2.0: patterns of collaboration in Wikipedia	David Laniado Riccardo Tasso	Wikipedia Collaboration network Online production Social network analysis	Hypertext	English	2011	The study of collaboration patterns in wikis can help shed light on the process of content creation by online communities. To turn a wiki's revision history into a collaboration network, we propose an algorithm that identifies as authors of a page the users who provided the most of its relevant content, measured in terms of quantity and of acceptance by the community. The scalability of this approach allows us to study the English Wikipedia community as a co-authorship network. We find evidence of the presence of a nucleus of very active contributors, who seem to spread over the whole wiki, and to interact preferentially with inexperienced users. The fundamental role played by this elite is witnessed by the growing centrality of sociometric stars in the network. Isolating the community active around a category, it is possible to study its specific dynamics and most influential authors.	0	1

Collective memory building in Wikipedia: The case of North African uprisings	Michela Ferron Paolo Massa	Wikipedia Web 2.0 Collective memory Revolution Traumatic event Egypt North Africa	WikiSym	English	2011	Since December 2010, a series of protests and uprisings have shocked North African countries such as Tunisia, Egypt, Libya, Syria, Yemen and more. In this paper, focusing mainly on the Egyptian revolution, we provide evidence of the intense edit activity occurred during these uprisings on the related Wikipedia pages. Thousands of people provided their contribution on the content pages and discussed improvements and disagreements on the associated talk pages as the traumatic events unfolded. We propose to interpret this phenomenon as a process of collective memory building and argue how on Wikipedia this can be studied empirically and quantitatively in real time. We explore and suggest possible directions for future research on collective memory formation of traumatic and controversial events in Wikipedia.	14	0

Content disputes in Wikipedia reflect geopolitical instability	Gordana Apic Matthew J. Betts Robert B. Russell			English	2011	Indicators that rank countries according socioeconomic measurements are important tools for regional development and political reform. Those currently in widespread use are sometimes criticized for a lack of reproducibility or the inability to compare values over time, necessitating simple, fast and systematic measures. Here, we applied the 'guilt by association' principle often used in biological networks to the information network within the online encyclopedia Wikipedia to create an indicator quantifying the degree to which pages linked to a country are disputed by contributors. The indicator correlates with metrics of governance, political or economic stability about as well as they correlate with each other, and though faster and simpler, it is remarkably stable over time despite constant changes in the underlying disputes. For some countries, changes over a four year period appear to correlate with world events related to conflicts or economic problems.	0	1

Creating online collaborative environments for museums: a case study of a museum wiki	Alison Hsiang-Yi Liu Jonathan P. Bowen	Knowledge management Collaborative learning Community of practice Museum Online community Wiki	Int. J. Web Based Communities	English	2011	Museums have been increasingly adopting Web 2.0 technology to reach and interact with their visitors. Some have experimented with wikis to allow both curators and visitors to provide complementary information about objects in the museum. An example of this is the Object Wiki from the Science Museum in London. Little has been done to study these interactions in an academic framework. In the field of knowledge management, the concept of 'communities of practice' has been posited as a suitable structure in which to study how knowledge is developed within a community with a common interest in a particular domain, using a sociological approach. Previously this has been used in investigating the management of knowledge within business organisations, teachers' professional development, and online e-learning communities. The authors apply this approach to a museum-based wiki to assess its applicability for such an endeavour.	1	0

Cultural bias in Wikipedia content on famous persons	Ewa S. Callahan Susan C. Herring		Journal of the American Society for Information Science and Technology	English	2011	Wikipedia advocates a strict "neutral point of view" (NPOV) policy. However, although originally a U.S-based, English-language phenomenon, the online, user-created encyclopedia now has versions in many languages. This study examines the extent to which content and perspectives vary across cultures by comparing articles about famous persons in the Polish and English editions of Wikipedia. The results of quantitative and qualitative content analyses reveal systematic differences related to the different cultures, histories, and values of Poland and the United States; at the same time, a U.S./English-language advantage is evident throughout. In conclusion, the implications of these findings for the quality and objectivity of Wikipedia as a global repository of knowledge are discussed, and recommendations are advanced for Wikipedia end users and content developers.	22	2
DBWiki: a structured wiki for curated data and collaborative data management	Peter Buneman James Cheney Sam Lindley Heiko Müller			English	2011	Wikis have proved enormously successful as a means to collaborate in the creation and publication of textual information. At the same time, a large number of curated databases have been developed through collaboration for the dissemination of structured data in specific domains, particularly bioinformatics. We demonstrate a general-purpose platform for collaborative data management, DBWiki, designed to achieve the best of both worlds. Our system not only facilitates the collaborative creation of a database; it also provides features not usually provided by database technology such as versioning, provenance tracking, citability, and annotation. In our demonstration we will show how DBWiki makes it easy to create, correct, discuss and query structured data, placing more power in the hands of users while managing tedious details of data curation automatically.	0	0

Deconstructing Wikipedia: Collaborative Content Creation in an Open Process Platform	Andrew Feldstein		Procedia - Social and Behavioral Sciences	English	2011	Collaboration in Wikipedia articles has widely been touted as a great leap forward and an example of how technology can be leveraged to improve collaborative processes. If we focus on the creation of individual articles, what does that creation process look like? Information was collected from the Revision History Statistics page of thirty Wikipedia featured articles to examine variables such as number of edits, number of editors and total edits by the largest contributors to a given article. This small pilot study suggests that the article creation process may more closely mirror the traditional writer/editor process than it does the “crowd as writer-editor”. It also raises questions about potential changes in how people view the content creation process.	0	0

Detection of Text Quality Flaws as a One-class Classification Problem	Maik Anderka Benno Stein Nedim Lipka	Information quality Wikipedia Quality Flaw Prediction One-class Classification	20th ACM Conference on Information and Knowledge Management (CIKM 11)	English	2011	For Web applications that are based on user generated content the detection of text quality flaws is a key concern. Our research contributes to automatic quality flaw detection. In particular, we propose to cast the detection of text quality flaws as a one-class classification problem: we are given only positive examples (= texts containing a particular quality flaw) and decide whether or not an unseen text suffers from this flaw. We argue that common binary or multiclass classification approaches are ineffective in here, and we underpin our approach by a real-world application: we employ a dedicated one-class learning approach to determine whether a given Wikipedia article suffers from certain quality flaws. Since in the Wikipedia setting the acquisition of sensible test data is quite intricate, we analyze the effects of a biased sample selection. In addition, we illustrate the classifier effectiveness as a function of the flaw distribution in order to cope with the unknown (real-world) flaw-specific class imbalances. Altogether, provided test data with little noise, four from ten important quality flaws in Wikipedia can be detected with a precision close to 1.	0	0

Don't bite the newbies: how reverts affect the quantity and quality of Wikipedia work	Aaron Halfaker Aniket Kittur John Riedl	WikiWork Wikipedia Experience Motivation Productivity Quality Revert	WikiSym	English	2011	Reverts are important to maintaining the quality of Wikipedia. They fix mistakes, repair vandalism, and help enforce policy. However, reverts can also be damaging, especially to the aspiring editor whose work they destroy. In this research we analyze 400,000 Wikipedia revisions to understand the effect that reverts had on editors. We seek to understand the extent to which they demotivate users, reducing the workforce of contributors, versus the extent to which they help users improve as encyclopedia editors. Overall we find that reverts are powerfully demotivating, but that their net influence is that more quality work is done in Wikipedia as a result of reverts than is lost by chasing editors away. However, we identify key conditions – most specifically new editors being reverted by much more experienced editors – under which reverts are particularly damaging. We propose that reducing the damage from reverts might be one effective path for Wikipedia to solve the newcomer retention problem.	0	0

Supak Anand Venkatraman Adrienne E. Zweifel Deborah A. Siegele James C. Hu			English	2011	EcoliWiki is the community annotation component of the PortEco (http://porteco.org; formerly EcoliHub) project, an online data resource that integrates information on laboratory strains of Escherichia coli, its phages, plasmids and mobile genetic elements. As one of the early adopters of the wiki approach to model organism databases, EcoliWiki was designed to not only facilitate community-driven sharing of biological knowledge about E. coli as a model organism, but also to be interoperable with other data resources. EcoliWiki content currently covers genes from five laboratory E. coli strains, 21 bacteriophage genomes, F plasmid and eight transposons. EcoliWiki integrates the Mediawiki wiki platform with other open-source software tools and in-house software development to extend how wikis can be used for model organism databases. EcoliWiki can be accessed online at http://ecoliwiki.net.	0	0

El potlatch digital. Wikipedia y el triunfo del procomún y el conocimiento compartido	Felipe Ortega Joaquín Rodríguez López			Spanish	2011	En el año 1968, Garret Hardin publicó en la revis­ta «Science» un artículo determinante, «The Trage­dy of the Commons», en el que reflexionaba sobre la dificultad de la gestión de los bienes y los recursos comunes y sobre el peligro al que estaba expuesta su subsistencia. La Premio Nobel de Economía Elinor Ostrom pasaría la mayor parte de su vida profesional investigando, precisamente, sobre los mecanismos de la acción colectiva y la gestión solidaria del proco­mún, intentando inferir de las buenas prácticas al­gunas características estructurales comunes. Con la in­vención de Internet y la digitalización del conoci­miento, resurge con vigor en versión digital el pro­blema analógico precedente: ¿cómo pueden surgir y autogestionarse comunidades online cuyo propósito es la generación de conocimiento compartido? Es decir, ¿cómo puede y debe gestionarse el procomún digital, el «digital commons»? Wikipedia ofrece un ejem­plo prototípico y floreciente de la construcción de una comunidad que consensúa sus políticas, esta­blece sus mecanismos internos de reconocimiento y orga­niza sus dispositivos de control y vigilancia, todo sin que circule efectivo de ninguna clase. El caso del «potlatch» canadiense nos sirve para comprender cómo en determinados contextos y circunstancias es nece­sario desprenderse del capital que se posee para que la comunidad lo devuelva y lo reintegre en forma de reconocimiento y renombre; cómo en determinados contextos culturales, la especie de capital que circula no es monetaria, sino simbólica, en forma de repu­tación y popularidad, y la lógica de su acumulación exige ser desinteresado para generar otra forma de interés. Así funcionan algunos de los casos más co­nocidos de Internet y así se ha convertido la Wikipe­dia en un caso del triunfo de la gestión del procomún y el conocimiento compartido.	0	0

Whereas our applications of semantic wikis in e-government focus on organizing and structuring architectural knowledge for reuse, the applications in distributed software development focus on searching and querying architectural knowledge. Yet, the emerging research challenges - alignment of knowledge models, knowledge versioning, change acknowledgements - are very similar.	0	0

Exploring linguistic points of view of Wikipedia	Paolo Massa Federico Scrinzi	Wikipedia Linguistic point of view Neutral point of view Cross-cultural Language Comparison Open source Web	WikiSym	English	2011	The 3 million articles of the English Wikipedia has been written since 2011 by more than 14 million volunteers. On each article, the community of editors strive to reach a neutral point of view, representing all significant views fairly, proportionately, and without bias. However, beside the English one, there are more than 270 Wikipedias in different languages and their relatively isolated communities of editors are not forced by the platform to discuss and negotiate their points of view. So the empirical question is: do communities on different languages editions of Wikipedia develop their own diverse Linguistic Points of View (LPOV)? To answer this question we created Manypedia, a web tool whose goal is to ease cross-cultural comparisons of Wikipedia language communities by analyzing their different representations of the same topic.	0	1
