|A Platform for Visually Exploring the Development of Wikipedia Articles||Erik Borra
|ICWSM '15 - 9th International AAAI Conference on Web and Social Media||English||May 2015||When looking for information on Wikipedia, Internet users generally just read the latest version of an article. However, in its back-end there is much more: associated to each article are the edit history and talk pages, which together entail its full evolution. These spaces can typically reach thousands of contributions, and it is not trivial to make sense of them by manual inspection. This issue also affects Wikipedians, especially the less experienced ones, and constitutes a barrier for new editor engagement and retention. To address these limitations, Contropedia offers its users unprecedented access to the development of an article, using wiki links as focal points.||0||0|
|Bots, bespoke, code and the materiality of software platforms||Geiger R.S.||Information Communication and Society||English||2014||This article introduces and discusses the role of bespoke code in Wikipedia, which is code that runs alongside a platform or system, rather than being integrated into server-side codebases by individuals with privileged access to the server. Bespoke code complicates the common metaphors of platforms and sovereignty that we typically use to discuss the governance and regulation of software systems through code. Specifically, the work of automated software agents (bots) in the operation and administration of Wikipedia is examined, with a focus on the materiality of code. As bots extend and modify the functionality of sites like Wikipedia, but must be continuously operated on computers that are independent from the servers hosting the site, they involve alternative relations of power and code. Instead of taking for granted the pre-existing stability of Wikipedia as a platform, bots and other bespoke code require that we examine not only the software code itself, but also the concrete, historically contingent material conditions under which this code is run. To this end, this article weaves a series of autobiographical vignettes about the author's experiences as a bot developer alongside more traditional academic discourse.||0||0|
|Collaborative development for setup, execution, sharing and analytics of complex NMR experiments||Irvine A.G.
|Journal of Magnetic Resonance||English||2014||Factory settings of NMR pulse sequences are rarely ideal for every scenario in which they are utilised. The optimisation of NMR experiments has for many years been performed locally, with implementations often specific to an individual spectrometer. Furthermore, these optimised experiments are normally retained solely for the use of an individual laboratory, spectrometer or even single user. Here we introduce a web-based service that provides a database for the deposition, annotation and optimisation of NMR experiments. The application uses a Wiki environment to enable the collaborative development of pulse sequences. It also provides a flexible mechanism to automatically generate NMR experiments from deposited sequences. Multidimensional NMR experiments of proteins and other macromolecules consume significant resources, in terms of both spectrometer time and effort required to analyse the results. Systematic analysis of simulated experiments can enable optimal allocation of NMR resources for structural analysis of proteins. Our web-based application (http://nmrplus.org) provides all the necessary information, includes the auxiliaries (waveforms, decoupling sequences etc.), for analysis of experiments by accurate numerical simulation of multidimensional NMR experiments. The online database of the NMR experiments, together with a systematic evaluation of their sensitivity, provides a framework for selection of the most efficient pulse sequences. The development of such a framework provides a basis for the collaborative optimisation of pulse sequences by the NMR community, with the benefits of this collective effort being available to the whole community. © 2013 Elsevier Inc.

|Extracting and displaying temporal and geospatial entities from articles on historical events||Chasin R.
|Computer Journal||English||2014||This paper discusses a system that extracts and displays temporal and geospatial entities in text. The first task involves identification of all events in a document followed by identification of important events using a classifier. The second task involves identifying named entities associated with the document. In particular, we extract geospatial named entities. We disambiguate the set of geospatial named entities and geocode them to determine the correct coordinates for each place name, often called grounding. We resolve ambiguity based on sentence and article context. Finally, we present a user with the key events and their associated people, places and organizations within a document in terms of a timeline and a map. For purposes of testing, we use Wikipedia articles about historical events, such as those describing wars, battles and invasions. We focus on extracting major events from the articles, although our ideas and tools can be easily used with articles from other sources such as news articles. We use several existing tools such as Evita, Google Maps, publicly available implementations of Support Vector Machines, Hidden Markov Model and Conditional Random Field, and the MIT SIMILE Timeline.||0||0|
|Open collaboration for innovation: Principles and performance||Levine S.S.
|Organization Science||English||2014||The principles of open collaboration for innovation (and production), once distinctive to open source software, are now found in many other ventures. Some of these ventures are Internet based: for example, Wikipedia and online communities. Others are off-line: they are found in medicine, science, and everyday life. Such ventures have been affecting traditional firms and may represent a new organizational form. Despite the impact of such ventures, their operating principles and performance are not well understood. Here we define open collaboration (OC), the underlying set of principles, and propose that it is a robust engine for innovation and production. First, we review multiple OC ventures and identify four defining principles. In all instances, participants create goods and services of economic value, they exchange and reuse each other's work, they labor purposefully with just loose coordination, and they permit anyone to contribute and consume. These principles distinguish OC from other organizational forms, such as firms or cooperatives. Next, we turn to performance. To understand the performance of OC, we develop a computational model, combining innovation theory with recent evidence on human cooperation. We identify and investigate three elements that affect performance: the cooperativeness of participants, the diversity of their needs, and the degree to which the goods are rival (subtractable). Through computational experiments, we find that OC performs well even in seemingly harsh environments: when cooperators are a minority, free riders are present, diversity is lacking, or goods are rival. We conclude that OC is viable and likely to expand into new domains. The findings also inform the discussion on new organizational forms, collaborative and communal.||0||0|
|Scalability of assessments of wiki-based learning experiences in higher education||Manuel Palomo-Duarte
|Computers in Human Behavior||English||2014||In recent years, the focus on higher education learning has shifted from knowledge to skills, with interpersonal skills likely being the most difficult to assess and work with. Wikis ease open collaboration among peers. A number of these skills can be objectively assessed by using wikis in an educational environment: collaborative writing, conflict resolution, group management, leadership, etc. However, when the number of students increases, their interactions usually increase at a higher rate. Under these circumstances, traditional assessment procedures suffer from scalability problems: manually evaluating in detail the information stored in a wiki to retrieve objective metrics becomes a complex and time-consuming task. Thus, automated tools are required to support the assessment of such processes. In this paper we compare seven case studies conducted in Computer Science courses of two Spanish universities: Cádiz and Seville. We comment on their different settings: durations, milestones, contribution sizes, weights in the final grade and, most importantly, their assessment methods. We discuss and compare the different methodologies and tools used to assess the desired skills in the context of each case study. © 2013 Elsevier Ltd. All rights reserved.||0||0|
|Wiki as a collaborative writing tool in teacher education: Evaluation and suggestions for effective use||Hadjerrouit S.||Computers in Human Behavior||English||2014||Wiki technology provides new opportunities to foster collaborative writing in teacher education. To empirically evaluate the level of collaborative writing in a wiki-based environment, this article used three methods and their combination. The first method was the history function that records all students' actions, enabling to trace all changes made in the wikis. The actions were analyzed in terms of number and percentage of contribution using a taxonomy categorized by 10 editorial types. The second method examined comments posted on the wiki discussion page to evaluate the level of collaboration. The third method provided feedback on the level of collaboration by means of peer assessment. The results show important differences in the types of contributions across the categories investigated. The results also reveal that the level of collaborative writing was lower than expected. Possible factors that may influence wiki-based collaborative writing are discussed. Finally, suggestions for effective use of wikis as collaborative writing tools in teacher education conclude the article. © 2013 Elsevier Ltd. All rights reserved.||0||0|
|A comparison of named entity recognition tools applied to biographical texts||Atdag S.
|2013 2nd International Conference on Systems and Computer Science, ICSCS 2013||English||2013||Named entity recognition (NER) is a popular domain of natural language processing. For this reason, many tools exist to perform this task. Amongst other points, they differ in the processing method they rely upon, the entity types they can detect, the nature of the text they can handle, and their input/output formats. This makes it difficult for a user to select an appropriate NER tool for a specific situation. In this article, we try to answer this question in the context of biographic texts. For this matter, we first constitute a new corpus by annotating 247 Wikipedia articles. We then select 4 publicly available, well known and free for research NER tools for comparison: Stanford NER, Illinois NET, OpenCalais NER WS and Alias-i LingPipe. We apply them to our corpus, assess their performances and compare them. When considering overall performances, a clear hierarchy emerges: Stanford has the best results, followed by LingPipe, Illionois and OpenCalais. However, a more detailed evaluation performed relatively to entity types and article categories highlights the fact their performances are diversely influenced by those factors. This complementarity opens an interesting perspective regarding the combination of these individual tools in order to improve performance.||0||0|
|A study of the Sudanese students' use of collaborative tools within Moodle Learning Management System||Elmahadi I.
|2013 IST-Africa Conference and Exhibition, IST-Africa 2013||English||2013||This study aims to investigate the use of Moodle Learning Management System by Sudanese students, particularly forum and wiki collaborative tools. The participants for this study were 92 undergraduate students from University of Khartoum in Sudan, where face to face collaboration is a common indigenous way of learning. The students took part in a Software Engineering blended learning course during the first semester of 2010-2011 academic year. The students' use was assessed using Moodle activity report tool, wiki entries, forum transcripts and students' final examination marks. Pearson product moment correlation coefficient was used to test for the relationship between using forum and wiki tools and the students' performance in the course. A detailed description of the students' use of the tools is provided. The study also showed a moderate correlation between participating in discussion forum and the students' performance in the course, and a low correlation between wiki participation and course performance.||0||0|
|An empirical study on faculty perceptions and teaching practices of wikipedia||Llados J.
|Proceedings of the European Conference on e-Learning, ECEL||English||2013||Some faculty members from different universities around the world have begun to use Wikipedia as a teaching tool in recent years. These experiences show, in most cases, very satisfactory results and a substantial improvement in various basic skills, as well as a positive influence on the students' motivation. Nevertheless and despite the growing importance of e-learning methodologies based on the use of the Internet for higher education, the use of Wikipedia as a teaching resource remains scarce among university faculty. Our investigation tries to identify which are the main factors that determine acceptance or resistance to that use. We approach the decision to use Wikipedia as a teaching tool by analyzing both the individual attributes of faculty members and the characteristics of the environment where they develop their teaching activity. From a specific survey sent to all faculty of the Universitat Oberta de Catalunya (UOC), pioneer and leader in online education in Spain, we have tried to infer the influence of these internal and external elements. The questionnaire was designed to measure different constructs: perceived quality of Wikipedia, teaching practices involving Wikipedia, use experience, perceived usefulness and use of 2.0 tools. Control items were also included for gathering information on gender, age, teaching experience, academic rank, and area of expertise. Our results reveal that academic rank, teaching experience, age or gender, are not decisive factors in explaining the educational use of Wikipedia. Instead, the decision to use it is closely linked to the perception of Wikipedia's quality, the use of other collaborative learning tools, an active attitude towards web 2.0 applications, and connections with the professional non-academic world. Situational context is also very important, since the use is higher when faculty members have got reference models in their close environment and when they perceive it is positively valued by their colleagues. As far as these attitudes, practices and cultural norms diverge in different scientific disciplines, we have also detected clear differences in the use of Wikipedia among areas of academic expertise. As a consequence, a greater application of Wikipedia both as a teaching resource and as a driver for teaching innovation would require much more active institutional policies and some changes in the dominant academic culture among faculty members.||0||0|
|An open conceptual framework for operationalising collective awareness and social sensing||Di Maio P.
|ACM International Conference Proceeding Series||English||2013||Substantial EU resources are being invested in research and practice emerging from the socio-technical convergence of networked technologies and social clusters, increasingly referred to as 'collective awareness' and 'social sensing' platforms. Novel concepts and tools are being developed to stimulate and promote technologies and environments, requiring some level of shared conceptualisation of the domain. This position paper identifies the need to capture and represent the knowledge and information in 'social sensing and collective awareness platforms' with minimal formalisms. It proposes steps toward the development of tools for collective development of shared conceptual models, to facilitate communication, knowledge sharing and collaboration in this emerging, and highly interdisciplinary research field.

|Analyzing task and technology characteristics for enterprise architecture management tool support||Hauder M.
|Proceedings - IEEE International Enterprise Distributed Object Computing Workshop, EDOC||English||2013||Adequate tool support for Enterprise Architecture (EA) and its respective management function is crucial for the success of the discipline in practice. However, currently available tools used in organizations focus on structured information neglecting the collaborative effort required for developing and planning the EA. As a result, utilization of these tools by stakeholders is often not sufficient and availability of EA products in the organization is limited. We investigate the integration of existing EA tools and Enterprise Wikis to tackle these challenges. We will describe how EA initiatives can benefit from the use and integration of an Enterprise Wiki with an existing EA tool. Main goal of our research is to increase the utilization of EA tools and enhance the availability of EA products by incorporating unstructured information content in the tools. For this purpose we analyze task characteristics that we revealed from the processes and task descriptions of the EA department of a German insurance organization and align them with technology characteristics of EA tools and Enterprise Wikis. We empirically evaluated these technology characteristics using an online survey with results from 105 organizations in previous work. We apply the technology-to-performance chain model to derive the fit between task and technology characteristics for EA management (EAM) tool support in order to evaluate our hypotheses.||0||0|
|COLLEAP - COntextual Language LEArning Pipeline||Wloka B.
|Lecture Notes in Computer Science||English||2013||In this paper we present a concept as well as a prototype of a tool pipeline to utilize the abundant information available on the World Wide Web for contextual, user driven creation and display of language learning material. The approach is to capture Wikipedia articles of the user's choice by crawling, to analyze the linguistic aspects of the text via natural language processing and to compile the gathered information into a visually appealing presentation of enriched language information. The tool is designed to address the Japanese language, with a focus on kanji, the pictographic characters used in Japanese scripture.||0||0|
|Collecting interaction traces in distributed semantic wikis||Le A.-H.
|ACM International Conference Proceeding Series||English||2013||In the Kolow project, our general objective is to develop an assistance engine suitable for distributed applications. In order to provide contextualized and relevant assistance, we feed the assistance engine with interaction traces. Interaction traces record events occurring while users are interacting with applications. These traces become containers of valuable knowledge to providing assistance. Collecting interaction traces is a challenging issue that has been thoroughly studied in the context of local applications. In contrast, few approaches focus on collecting interaction traces in distributed applications. Yet, when applications are distributed, collecting interaction traces is even more challenging because new difficulties arise, such as data synchronization and multi-synchronous collaboration. In this paper, we propose a model and a tool for collecting traces in a distributed environment. The originality of the model is that it is tailored to fit distributed applications. We implemented the model in Collectra, a tool to collect interaction traces in distributed web applications. Collectra collects interaction traces and stores them in a dedicated trace-base management system. We report on the experiments we have conducted in order to evaluate performances of Collectra (both response time and memory space). Results of the experiments show that Collectra performs well and that it can be used to support the assistance tasks carried out by the assistance engine. Copyright||0||0|
|Disambiguation to Wikipedia: A language and domain independent approach||Nguyen T.-V.T.||Lecture Notes in Computer Science||English||2013||Disambiguation to Wikipedia (D2W) is the task of linking mentions of concepts in text to their corresponding Wikipedia articles. Traditional approaches to D2W has focused either in only one language (e.g. English) or in formal texts (e.g. news articles). In this paper, we present a multilingual framework with a set of new features that can be obtained purely from the online encyclopedia, without the need of any natural language specific tool. We analyze these features with different languages and different domains. The approach shows as fully language-independent and has been applied successfully to English, Italian, Polish, with a consistent improvement. We show that only a sufficient number of Wikipedia articles is needed for training. When trained on real-world data sets for English, our new features yield substantial improvement compared to current local and global disambiguation algorithms. Finally, the adaption to the Bridgeman query logs in digital libraries shows the robustness of our approach even in the lack of disambiguation context. Also, as no natural language specific tool is needed, the method can be applied to other languages in a similar manner with little adaptation.||0||0|
|Early Prediction of Movie Box Office Success Based on Wikipedia Activity Big Data||Márton Mestyán
|PLoS ONE||English||2013||Use of socially generated "big data" to access information about collective states of the minds in human societies has become a new paradigm in the emerging field of computational social science. A natural application of this would be the prediction of the society's reaction to a new product in the sense of popularity and adoption rate. However, bridging the gap between "real time monitoring" and "early predicting" remains a big challenge. Here we report on an endeavor to build a minimalistic predictive model for the financial success of movies based on collective activity data of online users. We show that the popularity of a movie can be predicted much before its release by measuring and analyzing the activity level of editors and viewers of the corresponding entry to the movie in Wikipedia, the well-known online encyclopedia.||0||0|
|Enabling e-Collaboration and e-Pedagogy at an academic institution in the UAE||Tarazi J.
|Proceedings of the 2013 International Conference on Current Trends in Information Technology, CTIT 2013||English||2013||Academic Institutions have come a long way from the time when teachers used to teach the concepts using chalks and blackboards and students used to listen to the lecture and rapidly take down notes in their notebooks. The world has witnessed a sea of change in academic delivery and pedagogy of teaching. Other notable change that have been observed recently is the use of technology in teacher collaboration and academic administration. Paper attendance sheets have made way to electronic attendance musters, where teachers can mark students' presence, absence or even enter late marks, which can instantaneously be viewed across the system by different department chairs and administrators. Many Universities have started using Microsoft SharePoint as an academic e-Collaboration tool. Weblogs, or blogs are increasingly being used as collaborative and business intelligence tools by Corporate organizations. Wikis represent flexible tools functioning as open-ended environments for collaboration while also offering support for group writing support. This paper aims to portray the efforts undertaken by a leading academic institution on the United Arab Emirates (UAE) to incorporate technologies such as Microsoft SharePoint, Blogs and Wikis to reinforce its academic processes as well as provide for effective collaboration among its faculty and administration. It attempts at sketching a detailed account of how the institution tried to adopt e-Collaboration using Microsoft SharePoint and to develop an e-Pedagogy using Microsoft SharePoint, Wikis and Blogs using a structured methodology.||0||0|
|Encoding local correspondence in topic models||Mehdi R.E.
|Proceedings - International Conference on Tools with Artificial Intelligence, ICTAI||English||2013||Exploiting label correlations is a challenging and crucial problem especially in multi-label learning context. Labels correlations are not necessarily shared by all instances and have generally a local definition. This paper introduces LOC-LDA, which is a latent variable model that adresses the problem of modeling annotated data by locally exploiting correlations between annotations. In particular, we represent explicitly local dependencies to define the correspondence between specific objects, i.e. regions of images and their annotations. We conducted experiments on a collection of pictures provided by the Wikipedia 'Picture of the day' website, and evaluated our model on the task of 'automatic image annotation'. The results validate the effectiveness of our approach.||0||0|
|Evaluation of named entity recognition tools on microposts||Dlugolinsky S.
|INES 2013 - IEEE 17th International Conference on Intelligent Engineering Systems, Proceedings||English||2013||In this paper we evaluate eight well-known Information Extraction (IE) tools on a task of Named Entity Recognition (NER) in microposts. We have chosen six NLP tools and two Wikipedia concept extractors for the evaluation. Our intent was to see how these tools would perform on relatively short texts of microposts. Evaluation dataset has been adopted from the MSM 2013 IE Challenge. This dataset contained manually annotated microposts with classification restricted to four entity types: PER, LOC, ORG and MISC.||0||0|
|Experiences of Wiki topic teaching in postgraduate orthodontics: What do the learners think?||Ireland A.J.
|European Journal of Dental Education||English||2013||Introduction: Traditionally, the academic content of many 3-year full-time postgraduate courses in orthodontics in the UK has been delivered using tutorial and lecture-based teaching. This is often teacher lead rather than learner centred. Even with the advent of teaching modules on the national virtual learning environment, although well liked by students, is still often teacher lead. An alternative on-line approach to learner-centred teaching is to use Wikis. Materials and methods: Nine postgraduate students in the first term of their full-time 3-year specialist training programme at Bristol Dental School were divided into three groups and wrote a Wiki on three interrelated topics. This process was repeated in the second term using three different, but still interrelated topics. Following each, they were asked to give detailed feedback on their Wiki topic teaching. Results and discussion: The results showed that students felt writing the Wikis was useful for team work, provided a more learner-centred approach, created a body of work in a live format that would be useful for revision and was a welcome variation on traditional teaching methods. The biggest problem encountered was the IT platform used to create the Wikis. The students also felt the Wikis should be assessed as a piece of group work rather than as separate individuals. Conclusions: Wiki topic teaching is a useful tool in the teaching of postgraduate orthodontics providing variation and a more learner-centred approach. Further exploration of the available IT platforms is required.||0||0|
|Factors that determine the level of interaction in wikis, blogs and forums in private virtual communities||Valerio G.
|Proceedings of the IADIS International Conference Web Based Communities and Social Media 2013, Proceedings of the IADIS International Conference Collaborative Technologies 2013||English||2013||Transformative changes due to globalization and the revolution of knowledge are forcing organizations to constantly innovate and create new capabilities in order to meet the pressure of increasing performance. One of these innovations is the creation of virtual communities as mechanisms to facilitate knowledge transfer, especially when companies have distributed experts around the globe. CEMEX, a multinational Mexican company from the construction sector, deployed a the IBM Connections social media platform that internally is called SHIFT. With the general objective of identifying the factors that determine the level of interaction throughout Wikis, Blogs and Forums, a mixed nature research was performed. Relating the qualitative section of the research, 990 activities were observed and analyzed inside the platform. Different uses given to each of the tools were identified as well as the potential factors that could affect the interaction. Also, the quantitative statistical analysis determined which of these factors had the greatest impact on the interaction. Overall, the results showed that each tool has different determinant factors that impact the interaction level.||0||0|
|Interuniversity collaborative learning with wiki toolsets||Katzlinger E.
|Proceedings of the European Conference on e-Learning, ECEL||English||2013||This paper reports about a study of a collaborative learning scenario in university education within the subject of e-business. In business education advanced collaboration skills and media literacy are important for surviving in a globalized business where virtual communication between enterprises is part of the day-to-day business. To facilitate communication and collaboration between partners who work in different places at different schedules and even in different time zones, tools of web 2.0 are adequate in supporting this process. Especially working together with Wiki and similar collaborative Web-Tools satisfies asynchronous communication processes because all group members can trace changes, view the history of their colleagues work, and communicate about it. To transform these global working situations into higher education, a learning scenario was created where hundreds of students from two universities in Germany and Austria worked together in small interregional learning groups. Participating students had to collaborate virtually to prepare and report a shared case study online. The e-business case study had to be documented in a Wiki, and presented in the classroom of each university. When working together, learners used different tools for close virtual collaboration around a Wiki toolset such as forum, chat, video conferencing and other social media. Based on the didactical concept of moderate constructivism that should be best implemented by editing realistic problems and project tasks as well as cooperative learning, the case study method was chosen for collaboration. Students applied given case studies (e.g. from Harvard Business Review) or they worked out a business case from their own experience, which covered a range of upcoming e-business topics. An attending evaluation study with around 270 participants from two universities could show several substantive effects like • Tremendous influence of interregional group work for media competencies • Hidden social aspects and conflict potential • Scenario design and different media usage • Teaching effort vs. learning outcome of such a scenario • Learning impact for different student groups and learning styles: Who benefits most from such a learning scenario? Collaborative learning with a Web 2.0 tool like a Wiki in combination with the case study method can be quite effective in higher education settings. Methodical design of a learning scenario and choosing the media toolset is worth to plan carefully. Especially the presentation and debriefing requires a personal reflection of the case study itself and virtual collaboration about it in several groups. However this resulted in a high professional and social learning outcome on the part of the individual students. The online survey collected data from student groups who worked together in interuniversity or regional teams on case studies within the subject area e-business. The findings of this study show several interesting aspects of media usage and how students benefited from this learning scenario.||1||0|
|Invasion biology and the success of social collaboration networks, with application to wikipedia||Mangel M.
|Israel Journal of Ecology and Evolution||English||2013||We adapt methods from the stochastic theory of invasions - for which a key question is whether a propagule will grow to an established population or fail - To show how monitoring early participation in a social collaboration network allows prediction of success. Social collaboration networks have become ubiquitous and can now be found in widely diverse situations. However, there are currently no methods to predict whether a social collaboration network will succeed or not, where success is defined as growing to a specified number of active participants before falling to zero active participants. We illustrate a suitable methodology with Wikipedia. In general, wikis are web-based software that allows collaborative efforts in which all viewers of a page can edit its contents online, thus encouraging cooperative efforts on text and hypertext. The English language Wikipedia is one of the most spectacular successes, but not all wikis succeed and there have been some major failures. Using these new methods, we derive detailed predictions for the English language Wikipedia and in summary for more than 250 other language Wikipedias. We thus show how ideas from population biology can inform aspects of technology in new and insightful ways.||0||0|
|Learning with social technologies: Workplace learner experiences of wiki and blog and perceptions of PLE||Leino J.
|IFIP Advances in Information and Communication Technology||English||2013||As social technology use is increasing in e-learning, so is the need to complement theoretical work with studies of learner experiences of the new dynamics of e-learning to guide this development. We studied how 15 learners experienced social media tools in a long continuous professional development (CPD) pilot training tailored for a large insurance company. While the training included some contact lectures, it was mainly conducted through blog, wiki, chat, and discussion forum tools. As we have already discussed forum and chat use in another paper on a shorter CPD training (with 40 learners) and this study confirmed the results, we focus here on learner experiences of wiki and blog. While the wiki process was widely misunderstood, wiki and blog experiences organically led learners to consider their uses as a personal learning environment. As to blog, the learners who saw it as a tool for self-reflection perceived it positively while others did not, underlining that the benefits and goals of using social tools need to be explicated. Furthermore, social learning process needs to be designed and maintained, as busy workplace learners tend to focus on fulfilling requirements. Simply adding social technology does not necessarily lead to social e-learning.||0||0|
|Managing complexity: Strategies for group awareness and coordinated action in wikipedia||Gilbert M.
David W. McDonald
|Proceedings of the 9th International Symposium on Open Collaboration, WikiSym + OpenSym 2013||English||2013||In online groups, increasing explicit coordination can increase group cohesion and member productivity. On Wikipedia, groups called WikiProjects employ a variety of explicit coordination mechanisms to motivate and structure member contribution, with the goal of creating and improving articles related to particular topics. However, while explicit coordination works well for coordinating article-level actions, coordinating group tasks and tracking progress towards group goals that involve tracking hundreds or thousands of articles over time requires different coordination strategies. To lower the coordination cost of monitoring and task-routing, WikiProjects centralize coordination activity on WikiProject pages - "micro-sites" that provide a centralized repository of project tools, tasks and targets, and discussion for explicit group coordination. These tools can facilitate shared awareness of member and non-member editing activity on articles that the project cares about. However, whether these tools are as effective at motivating members as explicit coordination, and whether they elicit the same kind of contributions, has not been studied. In this study, we examine one such tool, Hot Articles, and compare its effect on the editing behavior of WikiProject members with a more common, explicit coordination mechanism: making edit requests on the project talk page.

|Method and tool support for classifying software languages with Wikipedia||Lammel R.
|Lecture Notes in Computer Science||English||2013||Wikipedia provides useful input for efforts on mining taxonomies or ontologies in specific domains. In particular, Wikipedia's categories serve classification. In this paper, we describe a method and a corresponding tool, WikiTax, for exploring Wikipedia's category graph with the objective of supporting the development of a classification of software languages. The category graph is extracted level by level. The extracted graph is visualized in a tree-like manner. Category attributes (i.e., metrics) such as depth are visualized. Irrelevant edges and nodes may be excluded. These exclusions are documented while using a manageable and well-defined set of 'exclusion types' as comments.||0||0|
|Parsit at Evalita 2011 dependency parsing task||Grella M.
|Lecture Notes in Computer Science||English||2013||This article describes the Constraint-based Dependency Parser architecture used at Evalita 2011 Dependency Parsing Task, giving a detailed analysis of the results obtained at the official evaluation. The Italian grammar has been expressed for the first time as a set of constraints and an ad-hoc constraints solver has been then applied to restrict possible analysis. Multiple solutions of a given sentence have been reduced to one by means of an evidence scoring system that makes use of an indexed version of Italian Wikipedia created for the purpose. The attachment score obtained is 96.16%, giving the best result so far for a dependency parser for the Italian language.||0||0|
|Promoting best practice sharing within organizations||Angelo Di Iorio
|WEBIST 2013 - Proceedings of the 9th International Conference on Web Information Systems and Technologies||English||2013||In recent years we are witnessing the wide adoption of Web 2.0's social software tools (blogs, microblogs, wiki, forums, shared calendars, etc.) within organizations complementing (or even replacing) existing enterprise applications. This trend is justified by the improved immediacy with which information can flow among the members of the organization and by a better support of agile, emergent cooperation models that re-shape the practices and the processes within organizations, allowing their continuous refinement and alignment with the organizations' missions and evolving know-how. One of the problems that arise in this new scenario is that as more and more practices and processes include interactions with several tools, often not controlled by the organization itself, it becomes more difficult to manage the knowledge they embody. In this paper we present an approach to mitigate this problem that plays nicely with the enhanced participation mechanisms triggered by social software. Our proposal revolves around the use of semantic wiki technologies as knowledge management tools; specifically we focus on dealing with practice and process-related knowledge, emerging from users interactions with Web 2.0 applications, and how this knowledge can effectively be represented, shared and made persistent.

|Proceedings of the 9th International Symposium on Open Collaboration, WikiSym + OpenSym 2013||English||2013||Wikisystems are proven to be good for producing text and knowledge in collaborative manner but they are not designed to handle large amounts of numerical data. We needed a system that is capable for producing text and run calculations from datasets. For this purpose we created Opasnet which is a Mediawiki with integrated statistical computing extension and an external database for data. In our demonstration we will show how R (statistical software) can be integrated into Mediawiki as an extension (R-Tools) and how it can be used directly from wiki pages. This extension enables users to write R-code, run it and see the results of the calculation on the wiki page. R-tools can use data from external databases and this functionality is also demonstrated. First R-Tools demonstration was held at Wikisym 2012 in Linz. Now we will focus on its new features developed within this year.

|Research collaboration tools for the U.S. Department of Defense||Schwalb S.I.||Information Services and Use||English||2013||America's adversaries have shown their ability to quickly incorporate new technologies that threaten the U.S. and its interests. The Defense Technical Information Center (DTIC) serves the Department of Defense (DoD) research and engineering community as the central resource for DoD-funded scientific, technical, engineering, and business information and exchange. Furthermore, DTIC fulfills a key role by producing secure collaborative tools that facilitate a rapid response to current and emerging threats. The new Research & Engineering (R&E) Gateway (created by DTIC), which includes DoDTechipedia, DoDTechSpace, Search and Analytics, and the Information Analysis Centers and Defense Innovation Marketplace, are aimed at enhancing DoD's ability to collaborate across the defense enterprise, identify solutions for technology challenges, and seek ways to ensure that taxpayer dollars are spent in an efficient manner. This article will examine the approach taken to develop the collaborative tools, intended goals, challenges to adoption of the sites, and some lessons learned. It will also review how DTIC has provided its registered customers with robust social media tools, albeit limited to the defense community.||0||0|
|Reviving chemistry through technology in engineering education||Cherukuri J.
|Proceedings - 2013 IEEE 5th International Conference on Technology for Education, T4E 2013||English||2013||Professors at VNR VJIET have found engineering students to be less interested in their chemistry courses than in their engineering ones. To motivate these students and enhance their educational experience in chemistry, we implemented changes to our curriculum with the support of a number of technological tools. One of these tools is MediaWiki which facilitated collaboration among instructors on lesson plans and learning outcomes. Other tools such as videos and animations allowed students to visualize the fabrication and working processes at various industries and laboratories. The changes made were successful in fostering student engagement and increased learning.||0||0|
|The Tanl lemmatizer enriched with a sequence of cascading filters||Giuseppe Attardi
Dei Rossi S.
|Lecture Notes in Computer Science||English||2013||We have extended an existing lemmatizer, which relies on a lexicon of about 1.2 millions form, where lemmas are indexed by rich PoS tags, with a sequence of cascading filters, each one in charge of dealing with specific issues related to out-of-dictionary words. The last two filters are devoted to resolve semantic ambiguities between words of the same syntactic category, by querying external resources: an enriched index built on the Italian Wikipedia and the Google index.||0||0|
|Three years of teaching using collaborative tools patterns and lessons learned||Trentini A.||CSEDU 2013 - Proceedings of the 5th International Conference on Computer Supported Education||English||2013||The author has taught computer science (Programming 101 and Operating Systems 101) for about fifteen years. He introduced the use of a student-collaborated wiki website for his courses about ten years ago. Then, three years ago, he also began extensively using a collaborative editor (Gobby) in classroom, to let students actively participate during lessons. This paper describes the author's course "workflow", summarizes tools (wiki and collaborative editor) functionalities, collects some context pattern and tries to draw a few conclusions (lessons learned) about the course methodology.||0||0|
|Tìpalo: A tool for automatic typing of DBpedia entities||Nuzzolese A.G.
|Lecture Notes in Computer Science||English||2013||In this paper we demonstrate the potentiality of Tìpalo, a tool for automatically typing DBpedia entities. Tìpalo identifies the most appropriate types for an entity in DBpedia by interpreting its definition extracted from its corresponding Wikipedia abstract. Tìpalo relies on FRED, a tool for ontology learning from natural language text, and on a set of graph-pattern-based heuristics which work on the output returned by FRED in order to select the most appropriate types for a DBpedia entity. The tool returns a RDF graph composed of rdf:type, rdfs:subClassOf, owl:sameAs, and owl:equivalentTo statements providing typing information about the entity. Additionally the types are aligned to two lists of top-level concepts, i.e., Wordnet supersenses and a subset of DOLCE Ultra Lite classes. Tìpalo is available as a Web-based tool and exposes its API as HTTP REST services.||0||0|
|Users' experiences and perceptions on using two wiki platforms for collaborative learning and knowledge management||Chu S.K.W.
|Online Information Review||English||2013||Purpose - This study aims to examine users' experiences and perceptions associated with the use of two wiki variants in the context of collaborative learning and knowledge management in higher education. Design/methodology/ approach - Participants included two groups of postgraduate students from a university in Hong Kong who used MediaWiki (n=21) and TWiki (n=16) in completing course requirements. Using a multiple case study approach and a mixed methods research design, data logs on the wiki platforms were downloaded and the contents were analysed. Students' perceptions were examined through a survey. Findings - The findings indicate that both wikis were regarded as suitable tools for group projects, and that they improved group collaboration and work quality. Both wikis were also viewed as enabling tools for knowledge construction and sharing. Research limitations/implications - This study provides insights that may inform the decisions of educators who are considering the use of wikis in their courses as a platform to enhance collaborative learning and knowledge management. Originality/value - Previous research has shown that wikis can be effectively used in education. However there are a number of wiki variants and it may be difficult to identify which variant would be the best choice. There is a dearth of research comparing the effectiveness of different types of wikis. This study compares two wiki variants on a number of outcomes which may provide some insights to teachers who are in the process of selecting an appropriate wiki for teaching and learning. © Copyright - 2013 Emerald Group Publishing Limited.

|Wikipedia as a tool for active learning. Experience gained within the framework of the wikifabricación project||Abellan-Nebot J.V.
|Materials Science Forum||English||2013||Wikipedia, the Free Encyclopedia, is one of the most visited websites on the Internet and it is a tool which students often use in their assignments, although they do not usually understand the basics underlying it. To overcome this limitation and promote the active learning approach in our courses, last year an educational innovation project was carried out that was aimed mainly at improving students' skills in technical writing as well as their ability to review the technical contents of the Wikipedias. Additionally, it sought to explore new opportunities that these tools can offer both teachers and students. This paper describes the experiment carried out in a second-year undergraduate engineering course, the results of which show that introducing activities such as edition and revision within Wikipedia is an interesting way to enhance transversal competencies as well as others related to the main contents of the course.||0||0|
|Work-to-rule: The emergence of algorithmic governance in wikipedia||Claudia Muller-Birn
|ACM International Conference Proceeding Series||English||2013||Research has shown the importance of a functioning governance system for the success of peer production communities. It particularly highlights the role of human coordination and communication within the governance regime. In this article, we extend this line of research by differentiating two categories of governance mechanisms. The first category is based primarily on communication, in which social norms emerge that are often formalized by written rules and guidelines. The second category refers to the technical infrastructure that enables users to access artifacts, and that allows the community to communicate and coordinate their collective actions to create those artifacts. We collected qualitative and quantitative data from Wikipedia in order to show how a community's consensus gradually converts social mechanisms into algorithmic mechanisms. In detail, we analyze algorithmic governance mechanisms in two embedded cases: The software extension "flagged revisions" and the bot "xqbot". Our insights point towards a growing relevance of algorithmic governance in the realm of governing large-scale peer production communities. This extends previous research, in which algorithmic governance is almost absent. Further research is needed to unfold, understand, and also modify existing interdependencies between social and algorithmic governance mechanisms.||0||0|
|Definition and multi-dimensional comparative analysis of ad hoc communities in Twitter||Macskassy S.A.||ICWSM 2012 - Proceedings of the 6th International AAAI Conference on Weblogs and Social Media||English||2012||We here present an early-stage prototype tool for defining and analyzing communities in Twitter. The tool takes a set of Twitter users and profiles them based on their tweets. This profiling is based on earlier work, where we map entities mentioned in tweets to Wikipedia entries, which in turn lets us profile a user based on the Wikipedia categories are related to his or her tweets. From here, we can define ad hoc topic-based communities (e.g., all users who discuss Wikipedia topic K). The tool is focused on contrast analysis, where we have baseline behavior or another community to compare against.

|How to get around with wikis in teaching||Kubincova Z.
|Lecture Notes in Computer Science||English||2012||Wikis were showed to be an interesting and powerful tool in education, supporting tasks starting from project management, collaborative data management, etc., up to more elaborate tasks such as collaborative production of lecture notes, reports, and essays. On the other hand, most wiki softwares were not created as educational tools in the first place, hence their application in curricula with groups of students faces some obstacles which need to be dealt with. These include motivating the students to engage with the tool, boosting collaboration between students, supervising and tracking student's activity, and evaluation. A number of tools were developed to enable or ease these tasks for the teacher. This paper takes a look on selected tools developed with this aim with two main goals: to produce a concise list of functionalities that are needed, and to compare and evaluate the tools that are available.||0||0|
|RareICT: A web-based resource to augment self-care and independence with a rare medical condition||Moen A.
|Work||English||2012||Objective: Everyday challenges to "live well" with a rare disorder, anorectal anomaly, was the starting point to design a social-software environment, called RareICT, to help patients and family members in their everyday, additional un-paid work. Participants: Persons with the rare disorder, family members and health providers were recruited to elaborate challenges to daily living given this condition. Methods: An exploratory study was designed, and we set up a series of participatory design workshops to explore challenges to everyday living with a rare medical condition. Results: Anorectal anomaly has few visible outward signs, and is often surrounded with secrecies. Findings shed light on efforts to maintain physical functioning, psychosocial and emotional wellbeing. For an affected person to "live well" modifications to everyday routines, along with management work, support work and planning work are required. Accumulating practical strategies, everyday experiences and knowledge, along with virtual access to peers may augment such health maintenance work if integrity, accountability and trust, confidentiality and privacy are maintained. Conclusion: A social-software environment was set up to offer co-evolving content and augment health-related decision-making at home. To evaluate the project will focus on interest in maintaining participation determined and how users benefit from services such as RareICT. © 2012 - IOS Press and the authors.

|The SEQanswers wiki: A wiki database of tools for high-throughput sequencing analysis||Li J.-W.
|Nucleic Acids Research||English||2012||Recent advances in sequencing technology have created unprecedented opportunities for biological research. However, the increasing throughput of these technologies has created many challenges for data management and analysis. As the demand for sophisticated analyses increases, the development time of software and algorithms is outpacing the speed of traditional publication. As technologies continue to be developed, methods change rapidly, making publications less relevant for users. The SEQanswers wiki (SEQwiki) is a wiki database that is actively edited and updated by the members of the SEQanswers community (http://SEQanswers.com/). The wiki provides an extensive catalogue of tools, technologies and tutorials for highthroughput sequencing (HTS), including information about HTS service providers. It has been implemented in MediaWiki with the Semantic MediaWiki and Semantic Forms extensions to collect structured data, providing powerful navigation and reporting features. Within 2 years, the community has created pages for over 500 tools, with approximately 400 literature references and 600 web links. This collaborative effort has made SEQwiki the most comprehensive database of HTS tools anywhere on the web. The wiki includes task-focused mini-reviews of commonly used tools, and a growing collection of more than 100 HTS service providers. SEQwiki is available at: http://wiki.SEQanswers.com/. © The Author(s) 2011. Published by Oxford University Press.||0||0|
|The Wasp System: An open source environment for managing and analyzing genomic data||McLellan A.S.
|Genomics||English||2012||The challenges associated with the management, analysis and interpretation of assays based on massively-parallel sequencing (MPS) are both individually complex and numerous. We describe what we believe to be the appropriate solution, one that represents a departure from traditional computational biology approaches. The Wasp System is an open source, distributed package written in Spring/J2EE that creates a foundation for development of an end-to-end solution for MPS-based experiments or clinical tests. Recognizing that one group will be unable to solve these challenges in isolation, we describe a nurtured open source development model that will allow the software to be collectively used, shared and developed. The ultimate goal is to emulate resources such as the Virtual Observatory of the astrophysics community, enabling computationally-inexpert scientists and clinicians to explore and interpret their MPS data. Here we describe the current implementation and development of the Wasp System and the roadmap for its community development.||0||0|
|Wiki-Pi: A Web-Server of Annotated Human Protein-Protein Interactions to Aid in Discovery of Protein Function||Orii N.
|PLoS ONE||English||2012||Protein-protein interactions (PPIs) are the basis of biological functions. Knowledge of the interactions of a protein can help understand its molecular function and its association with different biological processes and pathways. Several publicly available databases provide comprehensive information about individual proteins, such as their sequence, structure, and function. There also exist databases that are built exclusively to provide PPIs by curating them from published literature. The information provided in these web resources is protein-centric, and not PPI-centric. The PPIs are typically provided as lists of interactions of a given gene with links to interacting partners; they do not present a comprehensive view of the nature of both the proteins involved in the interactions. A web database that allows search and retrieval based on biomedical characteristics of PPIs is lacking, and is needed. We present Wiki-Pi (read Wiki-π), a web-based interface to a database of human PPIs, which allows users to retrieve interactions by their biomedical attributes such as their association to diseases, pathways, drugs and biological functions. Each retrieved PPI is shown with annotations of both of the participant proteins side-by-side, creating a basis to hypothesize the biological function facilitated by the interaction. Conceptually, it is a search engine for PPIs analogous to PubMed for scientific literature. Its usefulness in generating novel scientific hypotheses is demonstrated through the study of IGSF21, a little-known gene that was recently identified to be associated with diabetic retinopathy. Using Wiki-Pi, we infer that its association to diabetic retinopathy may be mediated through its interactions with the genes HSPB1, KRAS, TMSB4X and DGKD, and that it may be involved in cellular response to external stimuli, cytoskeletal organization and regulation of molecular activity. The website also provides a wiki-like capability allowing users to describe or discuss an interaction. Wiki-Pi is available publicly and freely at http://severus.dbmi.pitt.edu/wiki-pi/.||0||0|
|A common awareness and knowledge platform for studying and enabling independent living - CAPSIL||Bennis C.
|2010 4th International Conference on Pervasive Computing Technologies for Healthcare, Pervasive Health 2010||English||2010||The population of the world is growing older, and the balance of old to young is shifting so that by 2050 over 30% of the population is expected to be over 60 years old[l], with particularly high ratios of old to young in the EU, USA and Japan. CAPSIL is an FP7 Coordinating Support Action that incorporates a strategic international coalition of University and Industrial partners that already have extensive teams developing hardware/software/knowledge solutions to independent living based on user requirements. CAPSIL has two fundamental goals: 1. To carry out an analysis of the state of the art with regards to technology, healthcare and public policy in the EU, US and Japan for enabling independent living for older adults. Based on this analysis, develop a detailed roadmap for EU research to achieve effective and sustainable solutions for independent living 2. To support aging research by proposing procedures to incorporate all of these diverse solutions into WiKi entries (CAPSIL WiKi). It is our hope that these CAPSIL WiKi's will enable researchers and the ICT industry to get the information they need to quickly and easily test solutions for prolonging independent living within the many and various heterogeneous communities. In this paper we will summarise the principal findings of the CAPSIL Roadmap and present an overview of the main research gaps and recommendations for policy and research development. Finally, we will introduce the CAPSIL WiKi infrastructure.||0||0|

|On the utilization of web-based collaboration tools by student design teams||Koch M.D.
|ASME International Mechanical Engineering Congress and Exposition, Proceedings (IMECE)||English||2010||Over the last couple decades, the engineering world has seen a steady increase in collaboration and knowledge sharing through predominantly web-based means. Facilitated by a growing number of tools that allow for data and knowledge to be easily transferred, the technological landscape that organizations operate in is completely different than even a couple years ago. Specifically for engineering design, mainstream tools such as email, forums and wikis have been researched in both a professional sense as well as in design education. The following paper looks to build off these studies by identifying and studying the wide range of tools that engineering students utilize on their own accord to collaborate and progress towards finishing a design project. Specifically, mechanical and industrial engineering students enrolled in introductory design courses at Oregon State University and Humboldt State University were observed, interviewed and surveyed regarding these topics. The following will outline the findings from this study, with hopes that this work can help others in the design education field better understand and make better use of the tools that students prefer to use. Also, as the next generation of engineers moves onto professional careers, the ability of engineering firms to understand how the younger generation collaborates and communicates will be important in shaping how engineering firms efficiently utilize new web-based tools in engineering design.||0||0|
|Process makna - A semantic wiki for scientific workflows||Paschke A.
|CEUR Workshop Proceedings||English||2010||Virtual e-Science infrastructures supporting Web-based scientific workflows are an example for knowledge-intensive collaborative and weakly-structured processes where the interaction with the human scientists during process execution plays a central role. In this paper we propose the lightweight dynamic user-friendly interaction with humans during execution of scientific workflows via the low-barrier approach of Semantic Wikis as an intuitive interface for non-technical scientists. Our Process Makna Semantic Wiki system is a novel combination of an business process management system adapted for scientific workflows with a Corporate Semantic Web Wiki user interface supporting knowledge intensive human interaction tasks during scientific workflow execution.||0||0|
|Scholarly knowledge development and dissemination in an international context: Approaches and tools for higher education||Willis J.
|Computers in the Schools||English||2010||This paper looks at the process of collaboratively creating and disseminating information resources, such as journals, books, papers, and multimedia resources in higher education. This process has been facilitated and encouraged by two relatively new movements, open-source and, especially, open access. The most definitive expression of the principles of open access is the Budapest Open Access Initiative. It calls for the creation of journals that are freely available via the Internet to anyone. The broad principles of open access can be the foundation for creating many types of information resources-from online textbooks to sophisticated instructional videos. What distinguishes such open access resources is that they are distributed without charge to users and that most of the individual and institutional authors give permission for them to be revised, remixed, and reformed by users, who may then distribute the "new" version of the resource. Much of the work on open access information resources is collaborative and involves international teams with diverse experiences and areas of expertise. Such collaboration is not easy, but there is a growing set of electronic tools that support such work. The electronic toolbox for collaboratively creating new information resources includes tools that can serve as "electronic hallways" where potential collaborators can meet and interact informally; gateway Web sites and document repositories that support the exchange of information; Web tools that support groups with special interests; tools for supporting project teams; collaborative writing support systems including file sharing, document exchange, and version control software; wikis where a team can collaboratively write and revise documents, and project management software. There are also many avenues for disseminating information resources. These include open-access journals and the software packages that support them such as the Open Journal Systems package from the Public Knowledge Project, preprint and repository archives and the software for creating such archives (e.g., dspace, Fedora, Joomla, and Drupal), Web resources for indexing and locating relevant information, and international as well as virtual conferences and the software for operating such meetings. This paper explores the different approaches to both creating and disseminating information resources for higher education and evaluates some of the most commonly used software options for supporting these activities.||0||0|

|The work of sustaining order in wikipedia: The banning of a vandal||Geiger R.S.
|English||2010||In this paper, we examine the social roles of software tools in the English-language Wikipedia, specifically focusing on autonomous editing programs and assisted editing tools. This qualitative research builds on recent research in which we quantitatively demonstrate the growing prevalence of such software in recent years. Using trace ethnography, we show how these often-unofficial technologies have fundamentally transformed the nature of editing and administration in Wikipedia. Specifically, we analyze "vandal fighting" as an epistemic process of distributed cognition, highlighting the role of non-human actors in enabling a decentralized activity of collective intelligence. In all, this case shows that software programs are used for more than enforcing policies and standards. These tools enable coordinated yet decentralized action, independent of the specific norms currently in force. Copyright 2010 ACM.||0||4|

|Visual Semantic Client a visualization tool for semantic content||Wahl H.
|ICETC 2010 - 2010 2nd International Conference on Education Technology and Computer||English||2010||The University of Applied Sciences Technikum Wien is a fastgrowing education organization that actually offers a set of 12 bachelor and 14 master degree programs. Coordination of lectures and therefore quality management has become more and more difficult. Knowledge management in terms of lecture contents and professional skills of lecturers seems to be an unsolvable task. As a matter of f act, nobody is able to overlook all teaching details of the whole university. Although information is available in several databases and documents even getting an overview of all detail content of a single degree program turns out to be impossible. To overcome this problem the Technikum Wien started a project to extract selected information from documents and store it in a Semantic Wiki by automatically setting up entities and their relations. To improve usage of semantic content a software tool to browse the information categories and their relations has being developed. The "Visual Semantic Client" visualizes entities with their attributes and allows following or searching their relations. The paper shows the concepts behind, the system architecture and the current state of development.||0||0|
|A corporate semantic wiki for scientific workflows||Paschke A.
|Proceedings of I-KNOW 2009 - 9th International Conference on Knowledge Management and Knowledge Technologies and Proceedings of I-SEMANTICS 2009 - 5th International Conference on Semantic Systems||English||2009||State-of-the-art business process management tools provide only limited support for weakly-structured scientific workflow processes which involve knowledge intensive human interactions and are subject to frequent changes and agile compensations and exceptions. In order to address these shortcomings we propose a novel combination of a BPM system with a Corporate Semantic Web wiki. The user-friendliness of the later as regarding multi-site content generation and the power of semantic technologies as w.r.t. organizing and retrieving organizational knowledge, business rules and business vocabularies are likely to complement one another, leading to a new generation of collaborative Web 3.0 BPM tools.||0||0|

|Coordinating tasks on the commons: Designing for personal goals, expertise and serendipity||Krieger M.
|Conference on Human Factors in Computing Systems - Proceedings||English||2009||How is work created,assigned, and completed on large-scale, crowd-powered systems like Wikipedia? And what design principles might enable these federated online systems to be more effective? This paper reports on a qualitative study of work and task practices on Wikipedia. Despite the availability of tag-based community-wide task assignment mechanisms, informants reported that self-directed goals, within- topic expertise, and fortuitous discovery are more frequently used than community-tagged tasks. We examine how Wikipedia editors organize their actions and the actions of other participants, and what implications this has for understanding. and building tools for. crowd-powered systems, or any web site where the main force of production comes from a crowd of online participants. From these observations and insights, we developed WikiTasks. a tool that integrates with Wikipedia and supports both grassroots creation of site-wide tasks and self-selection of personal tasks, accepted from this larger pool of community tasks.

|Defining a universal actor content-element model for exploring social and information networks considering the temporal dynamic||Muller C.
|Proceedings of the 2009 International Conference on Advances in Social Network Analysis and Mining, ASONAM 2009||English||2009||The emergence of the Social Web offers new opportunities for scientists to explore open virtual communities. Various approaches have appeared in terms of statistical evaluation, descriptive studies and network analyses, which pursue an enhanced understanding of existing mechanisms developing from the interplay of technical and social infrastructures. Unfortunately, at the moment, all these approaches are separate and no integrated approach exists. This gap is filled by our proposal of a concept which is composed of a universal description model, temporal network definitions, and a measurement system. The approach addresses the necessary interpretation of Social Web communities as dynamic systems. In addition to the explicated models, a software tool is briefly introduced employing the specified models. Furthermore, a scenario is used where an extract from the Wikipedia database shows the practical application of the software.||0||0|
|Editing Wikipedia content by screen reader: Easier interaction with the Accessible Rich Internet Applications suite||Marina Buzzi
|Disability and Rehabilitation: Assistive Technology||English||2009||Purpose.This study aims to improve Wikipedia usability for the blind and promote the application of standards relating to Web accessibility and usability. Method.First, accessibility and usability of Wikipedia home, search result and edit pages are analysed using the JAWS screen reader; next, suggestions for improving interaction are proposed and a new Wikipedia editing interface built. Most of the improvements were obtained using the Accessible Rich Internet Applications WAI-ARIA suite, developed by the World Wide Web Consortium W3C within the framework of the Web Accessibility Initiative WAI. Last, a scenario of use compares interaction of blind people with the original and the modified interfaces. Results.Our study highlights that although all contents are accessible via screen reader, usability issues exist due to the user's difficulties when interacting with the interface. The scenario of use shows how building an editing interface with the W3C WAI-ARIA suite eliminates many obstacles that can prevent blind users from actively contributing to Wikipedia. Conclusion.The modified Wikipedia editing page is simpler to use via a screen reader than the original one because ARIA ensures a page overview, rapid navigation, and total control of what is happening in the interface.||0||0|

|Using a Wiki in nursing education and research||Kardong-Edgren S.E.
|International Journal of Nursing Education Scholarship||English||2009||With a wiki, learners can share information, resources, and experiences, and work together as a group. A wiki is equally valuable to a nursing research team: it can be used to communicate information to team members; foster collaboration among the team; disseminate resources, forms, and other documents for conducting the research; and share experiences with study implementation. Potential uses of a wiki in nursing education and research are discussed in this paper. One team's use of a wiki in a large multisite nursing education study is reported.||0||0|
|Disconnected in a connected world||Karpinski J.L.||Medical Reference Services Quarterly||English||2008||This article outlines five Web 2.0 resources and looks at the use of these tools among medical and nursing professionals and students at the Hospital, Medical School, and Nursing School of the University of Pennsylvania. Questionnaires showed that a majority of the individuals surveyed were unfamiliar with Web 2.0 resources. Additional respondents recognized the tools but did not use them in a medical or nursing context, with a minimal number using any tools to expand their medical or nursing knowledge. A lack of time to set up and use the resources, difficulty of set-up and use, skepticism about the quality of user-generated medical content, and a lack of perceived need for Web 2.0 resources contributed substantially to non-use. The University of Pennsylvania Biomedical Library is responding by increasing the availability of basic, quick, and easy-to-use instructional materials for selected Web 2.0 resources.||0||0|
|MiRDB: A microRNA target prediction and functional annotation database with a wiki interface||Xiaolong Wang||RNA||English||2008||MicroRNAs (miRNAs) are short noncoding RNAs that are involved in the regulation of thousands of gene targets. Recent studies indicate that miRNAs are likely to be master regulators of many important biological processes. Due to their functional importance, miRNAs are under intense study at present, and many studies have been published in recent years on miRNA functional characterization. The rapid accumulation of miRNA knowledge makes it challenging to properly organize and present miRNA function data. Although several miRNA functional databases have been developed recently, this remains a major bioinformatics challenge to miRNA research community. Here, we describe a new online database system, miRDB, on miRNA target prediction and functional annotation. Flexible web search interface was developed for the retrieval of target prediction results, which were generated with a new bioinformatics algorithm we developed recently. Unlike most other miRNA databases, miRNA functional annotations in miRDB are presented with a primary focus on mature miRNAs, which are the functional carriers of miRNA-mediated gene expression regulation. In addition, a wiki editing interface was established to allow anyone with Internet access to make contributions on miRNA functional annotation. This is a new attempt to develop an interactive community-annotated miRNA functional catalog. All data stored in miRDB are freely accessible at http://mirdb.org.

|On its way to K-12 classrooms, web 2.0 goes to graduate school||Norton P.
|Computers in the Schools||English||2008||As corporate and higher education settings increasingly use Web 2.0 tools, the time has come to think about preparing K-12 in-service teachers to find ways in which these tools might support classroom teaching and learning goals. This article describes a graduate course designed and taught in spring 2007. Using a modeling and situated learning framework, the article discusses Web 2.0 tools, K-12 education, and the course design. It also presents a summary of course participants' survey responses concerning their perceptions of their learning experience. Survey responses demonstrated that teacher-learners appreciated and endorsed the design of the course and felt their learning experiences scaffolded their ability to use Web 2.0 tools in their classroom and school context. The article concludes with several design recommendations and examples of classroom applications. © 2008 by The Haworth Press. All rights reserved.||0||0|

|Schema evolution in wikipedia - Toward a web Information system benchmark||Curino C.A.
|ICEIS 2008 - Proceedings of the 10th International Conference on Enterprise Information Systems||English||2008||Evolving the database that is at the core of an Information System represents a difficult maintenance problem that has only been studied in the framework of traditional information systems. However, the problem is likely to be even more severe in web information systems, where open-source software is often developed through the contributions and collaboration of many groups and individuals. Therefore, in this paper, we present an indepth analysis of the evolution history of the Wikipedia database and its schema; Wikipedia is the best-known example of a large family of web information systems built using the open-source software MediaWiki. Our study is based on: (i) a set of Schema Modification Operators that provide a simple conceptual representation for complex schema changes, and (ii) simple software tools to automate the analysis. This framework allowed us to dissect and analyze the 4.5 years of Wikipedia history, which was short in time, but intense in terms of growth and evolution. Beyond confirming the initial hunch about the severity of the problem, our analysis suggests the need for developing better methods and tools to support graceful schema evolution. Therefore, we briefly discuss documentation and automation support systems for database evolution, and suggest that the Wikipedia case study can provide the kernel of a benchmark for testing and improving such systems.||0||0|
|Improving flickr discovery through Wikipedias||Gobbo F.||CEUR Workshop Proceedings||English||2007||This paper explores how to discover unexpected information in existing folksonomies (serendipity) using extensive multilingual open source repositories as the underlying knowledge base, overcoming linguistic barriers at the same time. A web application called Flickrpedia is given as a practical example, using Flickr as the folksonomy and diverse natural language Wikipedias as the knowledge base.||0||0|
|Knowledge capturing tools for domain experts: Exploiting named entity recognition and n-ary relation discovery for knowledge capturing in e-science||Brocker L.
|CEUR Workshop Proceedings||English||2007||The success of the Semantic Web depends on the availability of content marked up using its description languages. Although the idea has been around for nearly a decade, the amount of Semantic Web content available is still fairly small. This is despite the existence of many digital archives containing lots of high quality collections which would, appropriately marked up, greatly enhance the reach of the Semantic Web. The archives themselves would benefit as well, by improved opportunities for semantic search, navigation and interconnection with other archives. The main challenge lies in the fact that ontology creation at the moment is a very detailed and complicated process. It mostly requires the service of an ontology engineer, who designs the ontology in accordance with domain experts. The software tools available, be it from the text engineering or the ontology creation disciplines, reflect this: they are built for engineers, not for domain experts. In order to really tap the potential of the digital collections, tools are needed that support the domain experts in marking up the content they understand better than anyone else. This paper presents an integrated approach to knowledge capturing and subsequent ontology creation, called WIKINGER, that aims at empowering domain experts to prepare their content for inclusion into the Semantic Web. This is done by largely automating the process through the use of named entity recognition and relation discovery.||0||0|
|Medical Librarian 2.0||Connor E.||Medical Reference Services Quarterly||English||2007||Web 2.0 refers to an emerging social environment that uses various tools to create, aggregate, and share dynamic content in ways that are more creative and interactive than transactions previously conducted on the Internet. The extension of this social environment to libraries, sometimes called Library 2.0, has profound implications for how librarians will work, collaborate, and deliver content. Medical librarians can connect with present and future generations of users by learning more about the social dynamics of Web 2.0's vast ecosystem, and incorporating some of its interactive tools and technologies (tagging, peer production, and syndication) into routine library practice. © 2007 by The Haworth Press, Inc.

|Onto wiki: A tool for social, semantic collaboration||Sören Auer
|CEUR Workshop Proceedings||English||2007||We present OntoWiki, a tool providing support for agile, distributed knowledge engineering scenarios. OntoWiki facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode for editing RDF content, similar to WYSIWYG for text documents. It fosters social collaboration aspects by keeping track of changes, allowing comments and discussion on every single part of a knowledge base, enabling to rate and measure the popularity of content and honoring the activity of users. OntoWiki enhances the browsing and retrieval by offering semantic enhanced search strategies. All these techniques are applied with the ultimate goal of decreasing the entrance barrier for projects and domain experts to collaborate using semantic technologies. In the spirit of the Web 2.0 OntoWiki implements an "architecture of participation" that allows users to add value to the application as they use it. It is available as open-source software and a demonstration platform can be accessed at http://3ba.se.||0||0|
|Wikis as an assessment tool for measuring the development of shared conceptual models||Flowers P.
|IADIS International Conference on Cognition and Exploratory Learning in Digital Age, CELDA 2006||English||2006||The purpose of this study is to investigate the use of Wikis as an effective tool to capture and assess the incremental progression of shared conceptual models of learners. The participants were eighteen (18) students in semester ranging from semester 4 to 13, working in groups of 3 enrolled in an online course at a major university in South-West Germany. Directions were given for students to complete a six point task online, using Wikis as their externalization tool, on the moodle platform. The final Wikis produced by the teams were modified on an average of 23.3 times per group (sd = 18) during the week long activity. In all cases, at least two students were actively involved in the development of the Wiki with some groups using all members. Although there is some room for improved design, the Wikis proved to be very effective in capturing the process of the conceptual model's development. Wikis have the potential to act as an effective tool for the assessment of the developmental process of mental models.||0||0|
|Wikis as online collaboration tool: An exploratory study in a hybrid learning environment||Wieland K.
|IADIS International Conference on Cognition and Exploratory Learning in Digital Age, CELDA 2006||English||2006||Several studies show that online learning can be as effective as face-to-face settings when there are social interaction and learning communities. The positive effects that are assigned to collaborative learning and communication do not automatically occur just because online environments make it possible. The purpose of this study is to explore the usability of Wikis as an online collaboration tool used for organizing, and presenting information developed in a group setting. Our results suggest that Wikis can be useful as collaborative tools suitable for group work assignments, despite problems such as vandalism, when students can create the content. The special features of Wikis qualify them as an online collaboration tool that can be used effectively in combination with other asynchronous methods such as chats or discussion boards to facilitate online group activities.||0||0|
|"Blogs" and "Wikis" are valuable software tools for communication within research groups||Sauer I.M.
|Artificial Organs||English||2005||Appropriate software tools may improve communication and ease access to knowledge for research groups. A weblog is a website which contains periodic, chronologically ordered posts on a common webpage, whereas a wiki is hypertext-based collaborative software that enables documents to be authored collectively using a web browser. Although not primarily intended for use as an intranet-based collaborative knowledge warehouse, both blogs and wikis have the potential to offer all the features of complex and expensive IT solutions. These tools enable the team members to share knowledge simply and quickly-the collective knowledge base of the group can be efficiently managed and navigated.||0||0|
