Citation needed: The dynamics of referencing in Wikipedia	Chih-Chun Chen Camille Roth	Wikipedia Collaborative system Authority		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	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	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		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	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	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	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	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	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	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	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		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	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	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	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	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	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	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
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	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
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	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
There is No Deadline - Time Evolution of Wikipedia Discussions	Andreas Kaltenbrunner David Laniado	Wikipedia Online discussion Temporal patterns H-index	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
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	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	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

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	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

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	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

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	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

Gender differences in Wikipedia editing	Judd Antin Raymond Yee Coye Cheshire Oded Nov	Wikipedia Gender Participation	English	2011	As Wikipedia has become an indispensable source of online information, concerns about who writes, edits, and maintains it have come to the forefront. In particular, the 2010 UNU-MERIT survey found evidence of a significant gender skew: fewer than 13% of Wikipedia contributors are women. However, the number of contributors is just one way to examine gender differences in contribution. In this paper we take a more fine-grained perspective by examining how much and what types of Wiki-work men and women tend to do. First, we find that the so-called “Gender Gap” in number of editors may not be as wide as prior studies have suggested. Second, although more than 80% of editors in our sample were men, among the bottom 75% of editors by activity level, we find that men and women made similar numbers of revisions. However, among the most active Wikipedians men tended to make many more revisions than women. Finally, we find that the most active women in our sample tended to make larger revisions than the most active men. We conclude by discussing directions for future research.	0	0
Hot off the Wiki: Dynamics, Practices, and Structures in Wikipedia’s Coverage of the Tōhoku Catastrophes	Brian Keegan Darren Gergle Darren Contractor	Wikipedia Breaking news Current events Network analysis Bipartite network Emergent group High tempo Collaboration	English	2011	Wikipedia editors are uniquely motivated to collaborate around current and breaking news events. However, the speed, urgency, and intensity with which these collaborations unfold also impose a substantial burden on editors’ abilities to effectively coordinate tasks and process information. We analyze the patterns of activity on Wikipedia following the 2011 Tōhoku earthquake and tsunami to understand the dynamics of editor attention and participation, novel practices employed to collaborate on these articles, and the resulting coauthorship structures which emerge between editors and articles. Our findings have implications for supporting future coverage of breaking news articles, theorizing about motivations to participate in online community, and illuminating Wikipedia’s potential role in storing cultural memories of catastrophe.	0	0

PukiWiki-Java Connector, a simple API for saving data of Java programs on a wiki	Takashi Yamanoue Kentaro Oda Koichi Shimozono	Java applets Collaboration Data store API Social coding	English	2011	Experimental implementation of SDK for Java programs, PukiWiki-Java Connector, which makes an illusion that wiki pages as persistent data store, is shown. A Java program of them can be running on a wiki page and it can save its data on the page. The Java program consists of PukiWiki which is a popular wiki in Japan, the plug-in which starts up Java Applets. .A Java Applet with default access privilege cannot store its data at the local host. We have constructed the API for the applets to ease data persistent at a remote host. We also combined the API and the wiki system by introducing a wiki plugin and tags for starting up Java Applets. Applet generated persistent data resides in wiki texts side by side. We have successfully ported useful programs such as a simple text editor, a simple music editor, a simple draw program and programming environments in a PukiWiki system using this connector.	2	3
The success of corporate wiki systems: an end user perspective	Zeeshan A. Bhatti Serge Baile Hina M. Yasin		English	2011	With the ever increasing use of Web 2.0 sites on the internet, the use of Web 2.0 based tools is now employed by organizations across the globe. One of the most widely used Web 2.0 tools in organizations is wiki technology, particularly in project management. It is important for organizations to measure the success of their wiki system implementation. With the advent of new technologies in the market and their deployment by the firms, it is necessary to investigate how they can help organizations execute processes in a better way. In this paper we present a theoretical model for the measurement of corporate wikis' success from the end-user's perspective based on the theoretical foundation of DeLone & McLean's IS success model [17]. We extend the model by incorporating contextual factors with respect to wiki technology in a project management task. This study intends to help firms to understand in a better way, how they can use wikis to achieve an efficient, effective and improved end-user performance. This would also be helpful for companies engaged in wiki development business to improve their products keeping in view the perceptions of wiki end-users.	0	0

Visualizing author contribution statistics in Wikis using an edit significance metric	Peter Kin-Fong Fong Robert P. Biuk-Aghai	Wikipedia Edit significance Information visualization Revision history Wiki	English	2011	Wiki articles tend to be edited multiple times by multiple authors. This makes it difficult to identify individual authors’ contributions by human observation alone. We calculate an edit significance metric, using different weights for different types of edits, which reflect the different value placed on them by wiki community members. We then aggregate edit significance values and present them as visualizations to the user to aid in perceiving extent and patterns of contributions.	0	0

What Wikipedia deletes: characterizing dangerous collaborative content	Andrew G. West Insup Lee	Wikipedia Collaboration Content removal Copyright Information security Redaction User generated content	English	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

Wikipedia category visualization using radial layout	Robert P. Biuk-Aghai Felix Hon Hou Cheang	Wikipedia Category Information visualization Radial layout Wiki	English	2011	Wikipedia is a large and popular daily information source for millions of people. How are articles distributed by topic area, and what is the semantic coverage of Wikipedia? Using manual methods it is impractical to determine this. We present the design of an information visualization tool that produces overview diagrams of Wikipedia’s articles distributed according to category relationships, and show examples of visualizing English Wikipedia.	0	0
Wikipedia world map: method and application of map-like wiki visualization	Cheong-Iao Pang Robert P. Biuk-Aghai	Wikipedia Category Information visualization Semantic coverage	English	2011	Wiki are popular platforms for collaborative editing. In volunteer-driven wikis such as Wikipedia, which attracts millions of authors editing articles on a diverse range of topics, contributors’ editing activity results in certain semantic coverage of topic areas. Obtaining an understanding of a given wiki’s semantic coverage is not easy. To solve this problem, we have devised a method for visualizing a wiki in a way similar to a geographic map. We have applied our method to Wikipedia, and generated visualizations for several Wikipedia language editions. This paper presents our wiki visualization method and its application.	0	0
A fielded wiki for personality genetics	Finn Årup Nielsen	Wiki Neuroinformatics Genetics Bioinformatics Meta-analysis	English	July 2010	(poster summary): A fielded wiki (a highly structured wiki) for genetic association studies with personality traits is described that features easy entry, on-the-fly meta-analysis of effect sizes and forest and funnel plotting with export of data in different formats. (paper abstract): I describe a fielded wiki, where a Web form interface allows the entry, analysis and visualization of results from scientific papers in the personality genetics domain. Papers in this domain typically report the mean and standard deviation of multiple personality trait scores from statistics on human subjects grouped based on genotype. The wiki organizes the basic data in a single table with fixed columns, each row recording statistical values with respect to a specific personality trait reported in a specific paper with a specific genotype group. From this basic data hard-coded meta-analysis can compute individual and combined effect sizes. The meta-analytic results are displayed in on-the-fly computed hyperlinked graphs and tables. Revision control on the basic data tracks changes and data may be exported to comma-separated files or in a MediaWiki template format.	7	1
STiki: An Anti-Vandalism Tool for Wikipedia Using Spatio-Temporal Analysis of Revision Metadata	Andrew G. West Sampath Kannan Insup Lee	Wikipedia Collaboration software Information security Intelligent routing Spatio-temporal processing	English	July 2010	STiki is an anti-vandalism tool for Wikipedia. Unlike similar tools, STiki does not rely on natural language processing (NLP) over the article or diff text to locate vandalism. Instead, STiki leverages spatio-temporal properties of revision metadata. The feasibility of utilizing such properties was demonstrated in our prior work, which found they perform comparably to NLP-efforts while being more efficient, robust to evasion, and language independent. STiki is a real-time, on-Wikipedia implementation based on these properties. It consists of, (1) a server-side processing engine that examines revisions, scoring the likelihood each is vandalism, and, (2) a client-side GUI that presents likely vandalism to end-users for definitive classiffcation (and if necessary, reversion on Wikipedia). Our demonstration will provide an introduction to spatio-temporal properties, demonstrate the STiki software, and discuss alternative research uses for the open-source code.	0	0

Chatting in the Wiki: synchronous-asynchronous integration	Robert P. Biuk-Aghai Keng Hong Lei	Asynchronous Communication Instant messaging Synchronous Wiki	English	2010	Wikis have become popular platforms for collaborative writing. The traditional production mode has been remote asynchronous and supported by wiki systems geared toward both asynchronous writing and asynchronous communication. However, many people have come to rely on synchronous communication in their daily work. This paper first discusses aspects of synchronous and asynchronous activity and communication and then proposes an integration of synchronous communication facilities in wikis. A prototype system developed by the authors is briefly presented.	0	0
Encouraging language students to contribute inflection data to Wiktionary	Zachary Kurmas	Wiktionary Inflection Language Wiki	English	2010	We propose building a computer program to simplify access to the inflection (i.e., “word ending”) data in Wiktionary. This program will make it easier to both (1) look up a word’s inflections and, more importantly, (2) edit incorrect inflections. We expect that such a program will encourage foreign language students to both use Wiktionary as a resource and contribute inflection and other grammar data toWiktionary. We believe that the resulting additional activity will make Wiktionary a better resource for students — especially students of those languages for which there are no cheap, comprehensive inflection resources — and provide data that will be beneficial to the wiki research community	1	0

Model-aware Wiki Analysis Tools: the Case of HistoryFlow	Oscar Díaz Gorka Puente		English	2010	Wikis are becoming mainstream. Studies confirm how wikis are finding their way into organizations. This paper focuses on requirements for analysis tools for corporate wikis. Corporate wikis differ from their grow-up counterparts such as Wikipedia. First, they tend to be much smaller. Second, they require analysis to be customized for their own domains. So far, most analysis tools focus on large wikis where handling efficiently large bulks of data is paramount. This tends to make analysis tools access directly the wiki database. This binds the tool to the wiki engine, hence, jeopardizing customizability and interoperability. However, corporate wikis are not so big while customizability is a desirable feature. This change in requirements advocates for analysis tools to be decoupled from the underlying wiki engines. Our approach argues for characterizing analysis tools in terms of their abstract analysis model (e.g. a graph model, a contributor model). How this analysis model is then map into wiki-implementation terms is left to the wiki administrator. The administrator, as the domain expert, can better assess which is the right terms/granularity to conduct the analysis. This accounts for suitability and interoperability gains. The approach is borne out for HistoryFlow, an IBM tool for visualizing evolving wiki pages and the interactions of multiple wiki authors.	8	0
Project management in the Wikipedia community	Hang Ung Jean M. Dalle		English	2010	A feature of online communities and notably Wikipedia is the increasing use of managerial techniques to coordinate the efforts of volunteers. In this short paper, we explore the influence of the organization of Wikipedia in so-called projects. We examine the project-based coordination activity and find bursts of activity, which appear to be related to individual leadership. Using time series, we show that coordination activity is positively correlated with contributions on articles. Finally, we bring evidence that this positive correlation is relying on two types of coordination: group coordination, with project leadership and articles editors strongly coinciding, and directed coordination, with differentiated online roles.	0	0

The Austrian way of Wiki(pedia)!: development of a structured Wiki-based encyclopedia within a local Austrian context	Christoph Trattner Ilire H. Mavriqi Denis Helic Helmut Leitner		English	2010	Although the success of online encyclopedias such as Wikipedia is indisputable, researchers have questioned usefulness of Wikipedia in educational settings. Problems such as copy&paste syndrome, unchecked quality, or fragmentation of knowledge have been recognized as serious drawbacks for a wide spread application of Wikipedia in universities or high schools. In this paper we present a Wiki-based encyclopedia called Austria-Forum that aims to combine openness and collaboration aspects of Wikipedia with approaches to build a structured, quality inspected, and context-sensitive online encyclopedia. To ensure tractability of the publishing process the system focuses on providing information within a local Austrian context. It is our experience that such an approach represents a first step of a proper application of online encyclopedias in educational settings.	0	0

What Did They Do? Deriving High-Level Edit Histories in Wikis	Peter Kin-Fong Fong Robert P. Biuk-Aghai	Wiki Revision history Text differencing Edit categorization Edit significance	English	2010	Wikis have become a popular online collaboration platform. Their open nature can, and indeed does, lead to a large number of editors of their articles, who create a large number of revisions. These editors make various types of edits on an article, from minor ones such as spelling correction and text formatting, to major revisions such as new content introduction, whole article re-structuring, etc. Given the enormous number of revisions, it is difficult to identify the type of contributions made in these revisions through human observation alone. Moreover, different types of edits imply different edit significance. A revision that introduces new content is arguably more significant than a revision making a few spelling corrections. By taking edit types into account, better measurements of edit significance can be produced. This paper proposes a method for categorizing and presenting edits in an intuitive way and with a flexible measure of significance of each individual editor’s contributions.	11	0

Who integrates the networks of knowledge in Wikipedia?	Iassen Halatchliyski Johannes Moskaliuk Joachim Kimmerle Ulrike Cress		English	2010	In the study presented in this article we investigated two related knowledge domains, physiology and pharmacology, from the German version of Wikipedia. Applying the theory of knowledge building to this community, we studied the authors of integrative knowledge. Network analysis indices of betweenness and closeness centrality were calculated for the network of relevant articles. We compared the work of authors who wrote exclusively in one domain with that of authors who contributed to both domains. The position of double-domain authors for a knowledge building wiki community is outstanding. They are not only responsible for the integration of knowledge from a different background, but also for the composition of the single-knowledge domains. Predominantly they write articles which are integrative and central in the context of such domains.	17	0

Wikipedia and the two-faced professoriate	Patricia L. Dooley		English	2010	A primary responsibility of university teachers is to guide their students in the process of using only the most accurate research resources in their completion of assignments. Thus, it is not surprising to hear that faculty routinely coach their students to use Wikipedia carefully. Even more pronounced anti-Wikipedia backlashes have developed on some campuses, leading faculty to forbid their students to use the popular on-line compendium of information. Within this context, but directing the spotlight away from students, this pilot study uses survey and content analysis research methods to explore how faculty at U.S. universities and colleges regard Wikipedia's credibility as an information source, as well as how they use Wikipedia in their academic work. The results of the survey reveal that while none of the university faculty who completed it regard Wikipedia as an extremely credible source of information, more than half stated it has moderate to high credibility, and many use it in both their teaching and research. The results of the content analysis component of the study demonstrates that academic researchers from across the disciplines are citing Wikipedia as a source of scholarly information in their peer-reviewed research reports. Although the study's research findings are not generalizable, they are surprising considering the professoriate's oft-stated lack of trust in Wikipedia.	0	2

Zawilinski: a library for studying grammar in Wiktionary	Zachary Kurmas	MediaWiki Wiktionary Inflection Language Parse Wiki	English	2010	We present Zawilinski, a Java library that supports the extraction and analysis of grammatical data in Wiktionary. Zawilinski can efficiently (1) filter Wiktionary for content pertaining to a specified language, and (2) extract a word’s inflections from its Wiktionary entry. We have thus far used Zawilinski to (1) measure the correctness of the inflections for a subset of the Polish words in the English Wiktionary and to (2) show that this grammatical data is very stable. (Only 131 out of 4748 Polish words have had their inflection data corrected.) We also explain Zawilinski’s key features and discuss how it can be used to simplify the development of additional grammar-based analyses.	3	2

A Jury of Your Peers: Quality, Experience and Ownership in Wikipedia	Aaron Halfaker Aniket Kittur Robert E. Kraut John Riedl	WikiWork Wikipedia Experience Ownership Peer Peer review Quality	English	2009	Wikipedia is a highly successful example of what mass collaboration in an informal peer review system can accomplish. In this paper, we examine the role that the quality of the contributions, the experience of the contributors and the ownership of the content play in the decisions over which contributions become part of Wikipedia and which ones are rejected by the community. We introduce and justify a versatile metric for automatically measuring the quality of a contribution. We ﬁnd little evidence that experience helps contributors avoid rejection. In fact, as they gain experience, contributors are even more likely to have their work rejected. We also ﬁnd strong evidence of ownership behaviors in practice despite the fact that ownership of content is discouraged within Wikipedia.	0	3

Assessing the quality of Wikipedia articles with lifecycle based metrics	Thomas Wöhner Ralf Peters		English	2009	The main feature of the free online-encyclopedia Wikipedia is the wiki-tool, which allows viewers to edit the articles directly in the web browser. As a weakness of this openness for example the possibility of manipulation and vandalism cannot be ruled out, so that the quality of any given Wikipedia article is not guaranteed. Hence the automatic quality assessment has been becoming a high active research field. In this paper we offer new metrics for an efficient quality measurement. The metrics are based on the lifecycles of low and high quality articles, which refer to the changes of the persistent and transient contributions throughout the entire life span.	0	2
Bipartite networks of Wikipedia's articles and authors: a meso-level approach	Rut Jesus Martin Schwartz Sune Lehmann	Wikipedia Bicliques Collaboration Meso-level	English	2009	This exploratory study investigates the bipartite network of articles linked by common editors in Wikipedia, 'The Free Encyclopedia that Anyone Can Edit'. We use the articles in the categories (to depth three) of Physics and Philosophy and extract and focus on significant editors (at least 7 or 10 edits per each article). We construct a bipartite network, and from it, overlapping cliques of densely connected articles and editors. We cluster these densely connected cliques into larger modules to study examples of larger groups that display how volunteer editors flock around articles driven by interest, real-world controversies, or the result of coordination in WikiProjects. Our results confirm that topics aggregate editors; and show that highly coordinated efforts result in dense clusters.	0	1

Evaluating the trustworthiness of Wikipedia articles through quality and credibility	Sai T. Moturu Huan Liu		English	2009	Wikipedia has become a very popular destination for Web surfers seeking knowledge about a wide variety of subjects. While it contains many helpful articles with accurate information, it also consists of unreliable articles with inaccurate or incomplete information. A casual observer might not be able to differentiate between the good and the bad. In this work, we identify the necessity and challenges for trust assessment in Wikipedia, and propose a framework that can help address these challenges by identifying relevant features and providing empirical means to meet the requirements for such an evaluation. We select relevant variables and perform experiments to evaluate our approach. The results demonstrate promising performance that is better than comparable approaches and could possibly be replicated with other social media applications.	0	0

Measuring the Wikisphere	Jeff C. Stuckman James Purtilo			2009	Due to the inherent difficulty in obtaining experimental data from wikis, past quantitative wiki research has largely been focused on Wikipedia, limiting the degree that it can be generalized. We developed WikiCrawler, a tool that automatically downloads and analyzes wikis, and studied 151 popular wikis running Mediawiki (none of them Wikipedias). We found that our studied wikis displayed signs of collaborative authorship, validating them as objects of study. We also discovered that, as in Wikipedia, the relative contribution levels of users in the studied wikis were highly unequal, with a small number of users contributing a disproportionate amount of work. In addition, power-law distributions were successfully fitted to the contribution levels of most of the studied wikis, and the parameters of the fitted distributions largely predicted the high inequality that was found. Along with demonstrating our methodology of analyzing wikis from diverse sources, the discovered similarities between wikis suggest that most wikis accumulate edits through a similar underlying mechanism, which could motivate a model of user activity that is applicable to wikis in general.	9	0

The singularity is not near: slowing growth of Wikipedia	Bongwon Suh Gregorio Convertino Ed H. Chi Peter Pirolli		English	2009	Prior research on Wikipedia has characterized the growth in content and editors as being fundamentally exponential in nature, extrapolating current trends into the future. We show that recent editing activity suggests that Wikipedia growth has slowed, and perhaps plateaued, indicating that it may have come against its limits to growth. We measure growth, population shifts, and patterns of editor and administrator activities, contrasting these against past results where possible. Both the rate of page growth and editor growth has declined. As growth has declined, there are indicators of increased coordination and overhead costs, exclusion of newcomers, and resistance to new edits. We discuss some possible explanations for these new developments in Wikipedia including decreased opportunities for sharing existing knowledge and increased bureaucratic stress on the socio-technical system itself.	0	10

Understanding learning: the Wiki way	Joachim Kimmerle Johannes Moskaliuk Ulrike Cress		English	2009	Learning "the wiki way", learning through wikis is a form of self-regulated learning that is independent of formal learning settings and takes place in a community of knowledge. Such a community may work jointly on a digital artifact to create new, innovative and emergent knowledge. We regard wikis as a prototype of tools for community-based learning, and point out five relevant features. We will present the co-evolution model, as introduced by Cress and Kimmerle [3][4], that may be understood as a framework to describe learning in the wiki way. This model describes collaborative knowledge building as a co-evolution between cognitive and social systems. To investigate learning the wiki way, we have to consider both individual processes and processes within the wiki, which represent the processes that are going on within a community. This paper presents three empirical studies that investigate learning the wiki way in a laboratory setting. We take a look at participants' contributions to a wiki indicating processes within the wiki community, and measure the extent of individual learning at the end of the experiment. Our conclusion is that the model of co-evolution has a strong impact on understanding learning the wiki way, may be helpful to designers of learning environments, and serve as framework for further research.	0	0

Wiki credibility enhancement	Felix Halim Wu Yongzheng Roland Yap		English	2009	Wikipedia has been very successful as an open encyclopedia which is editable by anybody. However, the anonymous nature of Wikipedia means that readers may have less trust since there is no way of verifying the credibility of the authors or contributors. We propose to automatically transfer external information about the authors from outside Wikipedia to Wikipedia pages. This additional information is meant to enhance the credibility of the content. For example, it could be the education level, professional expertise or affiliation of the author. We do this while maintaining anonymity. In this paper, we present the design and architecture of such system together with a prototype.	0	0

A Grammar for Standardized Wiki Markup	Martin Junghans Dirk Riehle Rama Gurram Matthias Kaiser Mário Lopes Umit Yalcinalp		English	2008	Today's wiki engines are not interoperable. The rendering engine is tied to the processing tools which are tied to the wiki editors. This is an unfortunate consequence of the lack of rigorously specified standards. This paper discusses an EBNF-based grammar for Wiki Creole 1.0, a community standard for wiki markup, and demonstrates its benefits. Wiki Creole is being specified using prose, so our grammar revealed several categories of ambiguities, showing the value of a more formal approach to wiki markup specification. The formalization of Wiki Creole using a grammar shows performance problems that today's regular-expression-based wiki parsers might face when scaling up. We present an implementation of a wiki markup parser and demonstrate our test cases for validating Wiki Creole parsers. We view the work presented in this paper as an important step towards decoupling wiki rendering engines from processing tools and from editing tools by means of a precise and complete wiki markup specification. This decoupling layer will then allow innovation on these different parts to proceed independently and as is expected at a faster pace than before.	0	0
A Method for Measuring Co-authorship Relationships in MediaWiki	Libby Veng-Sam Tang Robert P. Biuk-Aghai Simon Fong	Analysis Co-authorship Wiki	English	2008	Collaborative writing through wikis has become increasingly popular in recent years. When users contribute to a wiki article they implicitly establish a co-authorship relationship. Discovering these relationships can be of value, for example in finding experts on a given topic. However, it is not trivial to determine the main co-authors for a given author among the potentially thousands who have contributed to a given author’s edit history. We have developed a method and algorithm for calculating a co-authorship degree for a given pair of authors. We have implemented this method as an extension for the MediaWiki system and demonstrate its performance which is satisfactory in the majority of cases. This paper also presents a method of determining an expertise group for a chosen topic.	0	2

Assigning Trust to Wikipedia Content	B. Thomas Adler Krishnendu Chatterjee Luca de Alfaro Marco Faella Ian Pye Vishwanath Raman		English	2008	The Wikipedia is a collaborative encyclopedia: anyone can contribute to its articles simply by clicking on an "edit" button. The open nature of the Wikipedia has been key to its success, but has also created a challenge: how can readers develop an informed opinion on its reliability? We propose a system that computes quantitative values of trust for the text in Wikipedia articles; these trust values provide an indication of text reliability. The system uses as input the revision history of each article, as well as information about the reputation of the contributing authors, as provided by a reputation system. The trust of a word in an article is computed on the basis of the reputation of the original author of the word, as well as the reputation of all authors who edited text near the word. The algorithm computes word trust values that vary smoothly across the text; the trust values can be visualized using varying text-background colors. The algorithm ensures that all changes to an article's text are reflected in the trust values, preventing surreptitious content changes. We have implemented the proposed system, and we have used it to compute and display the trust of the text of thousands of articles of the English Wikipedia. To validate our trust-computation algorithms, we show that text labeled as low-trust has a significantly higher probability of being edited in the future than text labeled as high-trust.	0	5

We analyze and discuss, in particular, the correlation of various macroscopic indicators, structural features and governance policies with wiki growth patterns. While recent analyses of wiki dynamics have mostly focused on popular projects such as Wikipedia, we suggest research directions towards a more general theory of the dynamics of such communities.	0	1

Quantitative analysis and characterization of Wikipedia requests	Antonio J. Reinoso Jesús M. González-Barahona Felipe Ortega Gregorio Robles		English	2008	Our poster describes the quantitative analysis carried out to study the use of the Wikipedia system by its users with special focus on the identification of time and kind-of-use patterns, characterization of traffic and workload, and comparative analysis of different language editions. By filtering and classifying a large sample of the requests directed to the Wikimedia systems over 7 days we have been able to identify important information such us the targeted namespaces, the visited resources or the requested actions. The results found include the identification of weekly and daily patterns, and several correlations between different actions on the articles. In summary, the study shows an overall picture of how the most visited language editions of the Wikipedia are being accessed by their users.	0	0
Security of Community Developed and 3rd party Wiki Plug-ins	Andy Webber		English	2008	This paper discusses the significant security vulnerabilities that can occur in community developed wiki plug-ins and issues associated with managing the process of remediation. General guidance is given on how the vulnerabilities can be detected and rectified. The basis for the paper is direct experience with a number of community developed plug-ins for DokuWiki, although the findings have also been transferred to other wikis such as MediaWiki. The findings are also transferable to other similar web server technologies - such as blogs - that support similar plug-in frameworks.	0	0

Visualizing Wiki-Supported Knowledge Building: Co-Evolution of Individual and Collective Knowledge	Andreas Harrer Johannes Moskaliuk Joachim Kimmerle Ulrike Cress		English	2008	It is widely accepted that wikis are valuable tools for successful collaborative knowledge building. In this paper, we describe how processes of knowledge building with wikis may be visualized, citing Wikipedia as an example. The underlying theoretical basis of our paper is the framework for collaborative knowledge building with wikis, as introduced by Cress and Kimmerle. This model describes collaborative knowledge building as a co-evolution of individual and collective knowledge, or of cognitive and social systems respectively. These co-evolutionary processes may be visualized graphically, applying methods from social network analysis, especially those methods that take dynamic changes into account. For this purpose, we have undertaken to analyze, on the one hand, the temporal development of an article in the German version of Wikipedia and related articles that are linked to this core article. On the other hand, we analyzed the temporal development of those users who worked on these articles. The resulting graphics show an analogous process, both with regard to the articles that refer to the core article and to the users involved. These results provide empirical support for the co-evolution model. Some implications of our findings and the potential for future research on collaborative knowledge building with wikis and on the application of social network analysis are discussed at the end of the article.	0	2

WikiChanges - Exposing Wikipedia Revision Activity	Sérgio Nunes Cristina Ribeiro Gabriel David		English	2008	Wikis are popular tools commonly used to support distributed collaborative work. Wikis can be seen as virtual scrap-books that anyone can edit without having any specific technical know-how. The Wikipedia is a flagship example of a real-word application of wikis. Due to the large scale of Wikipedia it's difficult to easily grasp much of the information that is stored in this wiki. We address one particular aspect of this issue by looking at the revision history of each article. Plotting the revision activity in a timeline we expose the complete article's history in a easily understandable format. We present WikiChanges, a web-based application designed to plot an article's revision timeline in real time. WikiChanges also includes a web browser extension that incorporates activity sparklines in the real Wikipedia. Finally, we introduce a revisions summarization task that addresses the need to understand what occurred during a given set of revisions. We present a first approach to this task using tag clouds to present the revisions made.	0	1

A Framework for Studying the Use of Wikis in Knowledge Work Using Client-Side Access Data	Uri Dekel		English	2007	While measurements of wiki usage typically focus on the active contribution of content, information on the passive use of existing content can be valuable for a range of commercial and research purposes. In particular, such data is necessary for reconstructing the context or tracing the flow of information in settings where wikis are used as collaboration platforms in knowledge work that relies on specialized tools, such as software development. Meeting these needs requires detailed knowledge of user behavior, such as the duration for which a page was read and the sections visible at each point. This data cannot be collected by present wiki implementations and must be collected from the client-side, which presents a range of technical and privacy problems. In addition, this data must be correlated with traces of interaction with other tools. In this paper we present an approach for solving these problems in which scripts embedded by the wiki server are executed by the client browser, and report on the user’s interaction with that document along with relevant structural information. These reports are relayed to a comprehensive framework for storing and accessing interaction and context data from the wiki and from additional tools used in knowledge work. This framework can be used to correlate these traces to obtain a complete view of the user’s work across tools, or to approximate his context at specific points in time.	0	0
AniAniWeb: A Wiki Approach to Personal Home Pages	Jochen Rick		English	2007	This article reports on my dissertation research on personal home pages. It focuses on the design of AniAniWeb, a server-based system for authoring personal home pages. AniAniWeb builds on a wiki foundation to address many of the limitations of static technologies used to author personal home pages. This article motivates the technical hypotheses behind AniAniWeb and reflects on these hypotheses, based on a two year study of adopters using AniAniWeb in academia, a prominent vocational setting where personal home pages are important. In particular, I reflect on two broad categories: 1) the usefulness of wiki features (wiki authoring, wiki mark-up, and interaction / collaboration) to authoring personal home pages; 2) the other features (structure, designing looks, and access control) needed to make a wiki approach to personal home pages viable.	0	0
Building Collaborative Capacities in Learners: The M/Cyclopedia Project, Revisited	Axel Bruns Sal Humphreys	Wiki Tertiary education Pedagogy Produsage Social constructivism	English	2007	In this paper we trace the evolution of a project using a wiki-based learning environment in a tertiary education setting. The project has the pedagogical goal of building learners’ capacities to work effectively in the networked, collaborative, creative environments of the knowledge economy. The paper explores the four key characteristics of a ‘produsage’ environment and identifies four strategic capacities that need to be developed in learners to be effective ‘produsers’ (user/producers). A case study is presented of our experiences with the subject New Media Technologies, run at Queensland University of Technology. This progress report updates our observations made at the 2005 WikiSym conference.	0	0
Constructing text: Wiki as a toolkit for (collaborative?) learning	Andrea Forte Amy Bruckman	Collaboration Constructionism Education Knowledge building Open content Wiki	English	2007	Writing a book from which others can learn is itself a powerful learning experience. Based on this proposition, we have launched Science Online, a wiki to support learning in high school science classrooms through the collaborative production of an online science resource. Our approach to designing educational uses of technology is based on an approach to education called constructionism, which advocates learning by working on personally meaningful projects. Our research examines the ways that constructionism connects to collective models of knowledge production and learning such as Knowledge Building. In this paper, we explore ways that collaboration using wiki tools fits into the constructionist approach, we examine learning goals for youth growing up in a read-write culture, and we discuss preliminary findings in an ongoing year-long study of Science Online in the classroom. Despite the radically open collaboration afforded by wiki, we observe that many factors conspired to stymie collaborative writing on the site. We expected to find cultural barriers to wiki adoption in schools. Unexpectedly, we are also finding that the design of the wiki tool itself contributed barriers to collaborative writing in the classroom.	0	2
Cooperation and Quality in Wikipedia	Dennis M. Wilkinson Bernardo A. Huberman		English	2007	The rise of the Internet has enabled collaboration and cooperation on anunprecedentedly large scale. The online encyclopedia Wikipedia, which presently comprises 7.2 million articles created by 7.04 million distinct editors, provides a consummate example. We examined all 50 million edits made tothe 1.5 million English-language Wikipedia articles and found that the high-quality articles are distinguished by a marked increase in number of edits, number of editors, and intensity of cooperative behavior, as compared to other articles of similar visibility and age. This is significant because in other domains, fruitful cooperation has proven to be difficult to sustain as the size of the collaboration increases. Furthermore, in spite of the vagaries of human behavior, we show that Wikipedia articles accrete edits according to a simple stochastic mechanism in which edits beget edits. Topics of high interest or relevance are thus naturally brought to the forefront of quality.	0	1
DistriWiki: A Distributed Peer-to-Peer Wiki	Joseph C. Morris		English	2007	In this paper, we present DistriWiki, a peer-to-peer wiki. Motivated by the fact that the client-server architecture of the Web has limitations caused by the centralized nature of Web servers, we designed DistriWiki as a more open, more distributed alternative. In DistriWiki, each user’s computer acts as a peer that stores redundant copies of wiki pages; in this way, we can reduce bandwidth and hardware costs, reduce the number of failures due to hardware and configuration errors, and avoid centralized organizational control of the wiki pages.	0	0

On-line Collaborative Software Development via Wiki	Wenpeng Xiao Changyan Chi Min Yang		English	2007	Wiki is a collaborative authoring system for collective intelligence which is quickly gaining popularity in content publication. In software development communities, especially open source and global software development teams, wiki is already widely used for documentation and coordination purpose but not programming purpose. This paper presents a new programming approach based on wiki technology by which developers are able to experience "writing wiki page is wring source code". Moreover, developers are able to compile, execute and debug programs in wiki pages too. A prototype of such on-line collaborative software development environment, Galaxy Wiki, is developed in this environment iteratively in order to prove the concept.	0	1
Quantitative Analysis of the Wikipedia Community of Users	Felipe Ortega Jesús M. González-Barahona		English	2007	Many activities of editors in Wikipedia can be traced using its database dumps, which register detailed information about every single change to every article. Several researchers have used this information to gain knowledge about the production process of articles, and about activity patterns of authors. In this analysis, we have focused on one of those previous works, by Kittur et al. First, we have followed the same methodology with more recent and comprehensive data. Then, we have extended this methodology to precisely identify which fraction of authors are producing most of the changes in Wikipedia's articles, and how the behaviour of these authors evolves over time. This enabled us not only to validate some of the previous results, but also to find new interesting evidences. We have found that the analysis of sysops is not a good method for estimating different levels of contributions, since it is dependent on the policy for electing them (which changes over time and for each language). Moreover, we have found new activity patterns classifying authors by their contributions during specific periods of time, instead of using their total number of contributions over the whole life of Wikipedia. Finally, we present a tool that automates this extended methodology, implementing a quick and complete quantitative analysis ofevery language edition in Wikipedia.	0	4
Structuring Wiki Revision History	Mikalai Sabel		English	2007	Revision history of a wiki page is traditionally maintained as a linear chronological sequence. We propose to represent revision history as a tree of versions. Every edge in the tree is given a weight, called adoption coefficient, indicating similarity between the two corresponding page versions. The same coefficients are used to build the tree. In the implementation described, adoption coefficients are derived from comparing texts of the versions, similarly to computing edit distance. The tree structure reflects actual evolution of page content, revealing reverts, vandalism, and edit wars, which is demonstrated on Wikipedia examples. The tree representation is useful for both human editors and automated algorithms, including trust and reputation schemes for wiki.	0	1

Wiki-based process framework for blended learning	Marija Cubric		English	2007	With few exceptions, currently published research on theeducational use of wikis does not include how the learningactivities should be shaped, planned or enforced in a wiki. Inthis paper we aim to fill that gap by providing a framework forlearning and teaching processes supported by the use of wikis. Aninstance of that process framework ("feedback-driven" process) wasformulated and implemented through a series of trials performed atUniversity of Hertfordshire Business School during the course ofthe last two academic years to 2006/7. The results of the trialhave been collected and analyzed using the quantitative andqualitative methods and have led to the conclusion that studentsengagement with wiki-based learning activities is directlyproportional to the quality and frequency of tutors feedback andthe clarity of the underlying learning and teaching process.	0	1
WikiCreole: A Common Wiki Markup	Christoph Sauer Chuck Smith Tomas Benz		English	2007	In this paper, we describe the wiki markup language WikiCreole, how it was developed, and related work. Creole does not replace existing markup, but instead enables wiki users to transfer content seamlessly across wikis, and for novice users to contribute more easily. In proposing a subset of markup elements that is as non-controversial as possible, this markup has evolved from existing wiki markup, hence the name Creole: a stable language that originated from a non-trivial combination of two or more languages.	0	0

Constrained Wiki: an Oxymoron?	Angelo Di Iorio Stefano Zacchiroli	Wiki System Validation Assisted editing	English	2006	In this paper we propose a new wiki concept --- light constraints --- designed to encode community best practices and domain-specific requirements, and to assist in their application. While the idea of constraining user editing of wiki content seems to inherently contradict "The Wiki Way", it is well-known that communities of users involved in wiki sites have the habit of establishing best authoring practices. For domain-specific wiki systems which process wiki content, it is often useful to enforce some well-formedness conditions on specific page contents.This paper describes a general framework to think about the interaction of wiki system with constraints, and presents a generic architecture which can be easily incorporated into existing wiki systems to exploit the capabilities enabled by light constraints.	0	0
Corporate wiki users: results of a survey	Ann Majchrzak Christian Wagner Dave Yates		English	2006	A survey of 168 corporate wiki users was conducted. Findings indicate that corporate wikis appear to be sustainable. Users stated three main types of benefits from corporate wikis: enhanced reputation, work made easier, and helping the organization to improve its processes. These benefits were seen as more likely when the wiki was used for tasks requiring novel solutions and the information posted was from credible sources. Users acknowledged making a variety of contributions, which suggests that they could be categorized as "synthesizers" and "adders". Synthesizers" frequency of contribution was affected more by their impact on other wiki users, while adders" contribution frequency was affected more by being able to accomplish their immediate work.	0	1

Foucault@Wiki: first steps towards a conceptual framework for the analysis of Wiki discourses	Christian Pentzold Sebastian Seidenglanz	Wiki Wikipedia Computer-mediated communication Online collaboration Foucault Discourse theory	English	2006	In this paper, we examine the discursive situation of Wikipedia. The primary goal is to explore principle ways of analyzing and characterizing the various forms of communicative user interaction using Foucault"s discourse theory. First, the communicative situation of Wikipedia is addressed and a list of possible forms of communication is compiled. Second, the current research on the linguistic features of Wikis, especially Wikipedia, is reviewed. Third, some key issues of Foucault"s theory are explored: the notion of "discourse", the discursive formation, and the methods of archaeology and genealogy, respectively. Finally, first steps towards a qualitative discourse analysis of the English Wikipedia are elaborated. The paper argues, that Wikipedia can be understood as a discursive formation that regulates and structures the production of statements. Most of the discursive regularities named by Foucault are established in the collaborative writing processes of Wikipedia, too. Moreover, the editing processes can be described in Foucault"s terms as discursive knowledge production.	12	1
How and why Wikipedia works	Angela Beesley		English	2006	This talk discusses the inner workings of Wikipedia. Angela will address the roles, processes, and sociology that make up the project, with information on what happens behind the scenes and how the community builds and defends its encyclopedia on a daily basis. The talk will give some insight into why Wikipedia has worked so far and why we believe it will keep working in the the future despite the many criticisms that can be made of it. It is hoped that this review inspires further Wikipedia research. For this, please also see our Wikipedia Research workshop on Wednesday, which is open to walk-ins.	0	0

Translation the Wiki Way	Alain Désilets Lucas Gonzalez Sébastien Paquet Marta Stojanovic		English	2006	This paper discusses the design and implementation of processes and tools to support the collaborative creation and maintenance of multilingual wiki content. A wiki is a website where a large number of participants are allowed to create and modify content using their Web browser. This simple concept has revolutionized collaborative authoring on the web, enabling among others, the creation of Wikipedia, the world's largest online encyclopedia. On many of the largest and highest profile wiki sites, content needs to be provided in more than one language. Yet, current wiki engines do not support the efficient creation and maintenance of such content. Consequently, most wiki sites deal with the issue of multilingualism by spawning a separate and independent site for each language. This approach leads to much wasted effort since the same content must be researched, tracked and written from scratch for every language. In this paper, we investigate what features could be implemented in wiki engines in order to deal more effectively with multilingual content. We look at how multilingual content is currently managed in more traditional industrial contexts, and show how this approach is not appropriate in a wiki world. We then describe the results of a User-Centered Design exercise performed to explore what a multilingual wiki engine should look like from the point of view of its various end users. We describe a partial implementation of those requirements in our own wiki engine (LizzyWiki), to deal with the special case of bilingual sites. We also discuss how this simple implementation could be extended to provide even more sophisticated features, and in particular, to support the general case of a site with more than two languages. Finally, even though the paper focuses primarily on multilingual content in a wiki context, we argue that translating in this "Wiki Way", may also be useful in some traditional industrial settings, as a way of dealing better with the fast and ever-changing nature of our modern internet world.	0	2

Are Wikis Usable?	Alain Désilets Sébastien Paquet Norman G. Vinson	Wiki Collaborative Web-Authoring Groupware Hypertext Usability	English	2005	Wikis are simple to use, asynchronous, Web-based collaborative hypertext authoring systems which are quickly gaining in popularity. In spite of much anecdotal evidence to the effect that wikis are usable by non technical experts, this has never been studied formally. In this paper, we studied the usability of a wiki through observation and problem-solving interaction with several children who used the tool to collaboratively author hypertext stories over several sessions. The children received a minimal amount of instruction, but were able to ask for help during their work sessions. Despite minimal instruction, 5 out of 6 teams were able to complete their story. Our data indicate that the major usability problems were related to hyperlink management. We report on this and other usability issues, and provide suggestions for improving the usability of wikis. Our analysis and conclusions also apply to hypertext authoring with non wiki-based tools.	0	2
QwikWeb - Integrating mailing list and WikiWikiWeb for group communication	Kouichirou Eto Satoru Takabayashi Toshiyuki Masui	WikiWikiWeb Mailing list Groupware QuickML QwikWeb	English	2005	We have developed a new powerful group communication system qwikWeb, which is an integration of a WikiWikiWeb (wiki) and a mailing list system. Mailing lists are useful for exchanging dynamic information among people, but not useful for sharing static information. Wikis are useful for storing and editing static information on the Web, but sometimes people want to restrict the users or want to know who is responsible for the edited wiki page. Also, casual users cannot create a wiki site or a mailing list easily.We solved these problems by combining wiki and mailing list. Users of qwikWeb can create a wiki site and a mailing list simply by sending an e-mail message to the qwikWeb server, and start exchanging information by using the mailing list. All the messages sent to the mailing list are stored as newly created wiki pages, and they can be edited as standard wiki pages.In this paper, we describe the basic ideas, implementation details, and user experiences of the system.	4	0
SmallWiki - A Meta-Described Collaborative Content Management System	Stephane Ducasse Lukas Renggli Roel Wuyts	Object-Oriented Programming Meta-modeling Design and Implementation Seaside Smalltalk	English	2005	Wikis are often implemented using string-based approaches to parse and generate their pages. While such approaches work well for simple wikis, they hamper the customization and adaptability of wikis to the variety of end-users when more sophisticated needs are required (i.e., different output formats, user-interfaces, wiki management, security policies, ...). In this paper we present SmallWiki, the second version of a fully object-oriented implementation of a wiki. SmallWiki is implemented with objects from the top to the bottom and it can be customized easily to accommodate new needs. In addition, SmallWiki is based on a powerful meta-description called Magritte that allows one to create user-interface elements declaratively.	1	0
TWiki-based facilitation in a newly formed academic community of practice	Elizabeth Da Lio Lucia Fraboni Tommaso Leo	Wiki-based case study TWiki Wiki-based community of practice Collaboration	English	2005	This paper reports on the first results of an on-going project whose aim is to evaluate whether a wiki-based knowledge sharing tool like TWiki facilitates effective processes of knowledge building, sharing and transfer and fosters collaboration in a community of practice made up of Italian teachers. The project started in October 2004 and first data were collected five months later. The project was an attempt to provide them the opportunity to build more productive working relationships, stimulate new ideas, take advantage from the sharing of the broad range of professional knowledge and expertise that resides within the school. We chose TWiki as collaborative environment because its features met our needs quite well: it is open, free, easy to customize, has a versioning system and does not use proprietary technology.	1	0
Wiki Communities in the Context of Work Processes	Frank Fuchs-Kittowski Andre Köhler	Ontology Wiki Community Cooperative knowledge generation Knowledge work Work processes Knowledge process Process-oriented knowledge structures	English	2005	In this article we examine the integration of communities of practice supported by a wiki into work processes. Linear structures are often inappropriate for the execution of knowledge-intensive tasks and work processes. The latter are characterized by non-linear sequences and dynamic social interaction. Communities of practice, however, often lack the „guiding light” needed to structure their work. We discuss the primary requirements for the integration of formally described knowledge-intensive processes into the dynamic social processes of knowledge generation in communities of practice and use the wiki approach for their support. We present our approach for an appropriate interface to integrate wiki communities into process structures and an information retrieval algorithm based on it to connect the process-oriented structures with community-oriented wiki structures. We show the prototypical realization of the concept by a brief example.	0	1
Wiki Templates - Adding Structure Support to Wikis on Demand	Anja Haake Stephan Lukosch Till Schümmer	Wiki Template Tailoring Structural editing and viewing	English	2005	This paper introduces the concept of wiki templates that allows end-users to determine the structure and appearance of a wiki page. In particular, this better supports editing of structured wiki pages. Wiki templates may be adapted (defined and redefined) by end-users. They may be applied if found helpful, but need not to be used, thus maintaining the simple wiki editing way. In addition, we introduce a methodology to reuse wiki templates among different wiki instances. We show how wiki templates have been successfully used in real-world applications in our CURE wiki engine.	1	0
WikiGateway - A Library for Interoperability and Accelerated Wiki Development	Bayle Shanks	Wiki Interwiki Interoperability WikiGateway Client-side wiki WikiClient Middleware Atom WebDAV WikiRPCInterface Wiki XMLRPC	English	2005	WikiGateway is an open-source suite of tools for automated interaction with wikis: * Python and Perl modules with functions like getPage, putPage, getRecentChanges, and more. * A mechanism to add DAV, Atom, or XMLRPC capabilities to any supported wiki server. * A command-line tool with functionality similar to the Perl and Python modules. * Demo applications built on top of these tools include a wiki copy command, a spam-cleaning bot, and a tool to recursively upload text files inside a directory structure as wiki pages. All WikiGateway tools are compatible with a number of different wiki engines. Developers can use WikiGateway to hide the differences between wiki engines and build applications which interoperate with many different wiki engines.	0	0
WikiWiki Weaving Heterogeneous Software Artifacts	Ademar Aguiar Gabriel David	Software documentation Web-based documentation Wiki	English	2005	Good documentation benefits every software development project, especially large ones, but it can be hard, costly, and tiresome to produce when not supported by appropriate tools and methods. The documentation of a software system uses different artifacts, namely source code, for low-level internal documentation, and specific-purpose models and documents, for higher-level external documentation (e.g. requirements documents, use-case specifications, design notebooks, and reference manuals). All these artifacts require continual review and modification throughout the life-cycle to preserve their consistency and value. Good software documents are often heterogeneous, i.e., they combine different kinds of contents (text, code, models, images) gathered from separate software artifacts, a combination usually difficult to maintain as the system evolves over time, considering that source code, models and documents are typically produced and maintained separately in multiple sources using different environments and editors. This paper presents a wiki that helps on quickly weaving different kinds of contents into a single heterogeneous document, whilst preserving its semantic consistency. The fundamental goal of this wiki (XSDoc Wiki) is to reduce the development–documentation gap by making documentation more convenient and attractive to developers. An example taken from the JUnit framework documentation helps to illustrate the features more relevant to do such weaving.	1	0

Wikis in Teaching and Assessment - The M/Cyclopedia Project	Axel Bruns Sal Humphreys	Wiki Tertiary education Pedagogy Social constructivism Assessment	English	2005	In a knowledge-based, networked economy, students leaving university need to have attained skills in collaborative and creative project-based work and to have developed critical, reflective practices. This paper outlines how a wiki can been used as part of social constructivist pedagogical practice which aims to develop advanced ICT literacies in university students. The paper describes the implementation of a wiki-based project as part of a subject in New Media Technologies at Queensland University of Technology. We discuss the strengths and challenges involved in using networked, collaborative learning strategies in institutional environments that still operate in traditional paradigms.	3	0
