Who integrates the networks of knowledge in Wikipedia? BIBAKFull-Text 1
  Iassen Halatchliyski; Johannes Moskaliuk; Joachim Kimmerle; Ulrike Cress
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.

What did they do?: deriving high-level edit histories in Wikis BIBAKFull-Text 2
  Peter Kin-Fong Fong; Robert P. Biuk-Aghai
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.

Deep hypertext with embedded revision control implemented in regular expressions BIBAFull-Text 3
  Victor Grishchenko
While text versioning was definitely a part of the original hypertext concept [21, 36, 44], it is rarely considered in this context today. Still, we know that revision control underlies the most exciting social co-authoring projects of the today's Internet, namely the Wikipedia and the Linux kernel. With an intention to adapt the advanced revision control technologies and practices to the conditions of the Web, the paper reconsiders some obsolete assumptions and develops a new versioned text format perfectly processable with standard regular expressions (PCRE [6]). The resulting deep hypertext model allows instant access to past/concurrent versions, authorship, changes; enables deep links to reference changing parts of a changing text. Effectively, it allows distributed and real-time revision control on the Web, implementing the vision of co-evolution and mutation exchange among multiple competing versions of the same text.
Semantic search on heterogeneous Wiki systems BIBAKFull-Text 4
  Fabrizio Orlandi; Alexandre Passant
This paper describes a system to enable semantic search across heterogeneous wikis in an unified way using Semantic Web technologies. In particular, we discuss (i) how we designed a common model for representing social and structural wiki features and (ii) how we extracted semantic data from wikis using Mediawiki and Dokuwiki. On this basis, we show how we built and efficient application with a simple user-interface enabling semantic searching and browsing capabilities on the top of different interlinked wikis.

Wikis at work: success factors and challenges for sustainability of enterprise Wikis BIBAKFull-Text 5
  Jonathan Grudin; Erika Shehan Poole
We examined wiki use in a range of enterprise settings. We found many thriving wikis, but they were a minority of the thousands for which we obtained data. Even an actively used wiki can disappoint some important stakeholders. Careful stakeholder analysis and education may be crucial to successful wiki deployment. We identify a range of success factors, sources of wiki abandonment, and approaches to addressing the challenges. Some of our observations may extend to other social media.

Model-aware Wiki analysis tools: the case of HistoryFlow BIBAKFull-Text 6
  Oscar Díaz; Gorka Puente
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.

ThinkFree: using a visual Wiki for IT knowledge management in a tertiary institution BIBAKFull-Text 7
  Christian Hirsch; John Hosking; John Grundy; Tim Chaffe
We describe ThinkFree, an industrial Visual Wiki application which provides a way for end users to better explore knowledge of IT Enterprise Architecture assets that is held within a large enterprise wiki. The application was motivated by the difficulty users were facing navigating and understanding enterprise architecture information in a large corporate wiki. ThinkFree provides a graph based interactive visualization of IT assets which are described using the Freebase semantic wiki. It is used to visualize relationships between those assets and navigate between them. We describe the motivation for the development of ThinkFree, its design and implementation. Our experiences in corporate rollout of the application are discussed, together with the strengths of weaknesses of the approach we have taken and lessons learned from ThinkFree's development and deployment.

Openness as an asset: a classification system for online communities based on actor-network theory BIBAKFull-Text 8
  Annalisa Pelizza
There exists a lack of consensus among scholars about the definition and categorization of technology-mediated communities. If these divergences hamper the possibility to devise a unique definition of online communities, some principia divisionis can nonetheless be found, in order to handle heterogeneity.
   Drawing upon case studies selected from Ars Electronica's Digital Communities competition, this paper analyses the limits of the categorization variables traditionally used to classify online communities, and proposes a new classification system made of two variables measuring the "openness" of the community. The first variable enacts Actor-Network Theory's distinction between mediators and intermediaries, while the second considers the degree of openness of the regimes of access and visibility enabled by groupware architectures.
   On-field evaluation of this classification system shows three advantages: since it is based on the abstract criterion "openness", it does not arbitrarily reduce the richness of the techno-social world, but rather allows researchers to cluster few types of online community. In addition, it is of some merit in tracking innovation in techno-social assemblages.

The Austrian way of Wiki(pedia)!: development of a structured Wiki-based encyclopedia within a local Austrian context BIBAKFull-Text 9
  Christoph Trattner; Ilire Hasani-Mavriqi; Denis Helic; Helmut Leitner
Although the success of online encyclopedias such as Wiki-pedia 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.

'[B]ut this is blog maths and we're free to make up conventions as we go along': Polymath1 and the modalities of 'massively collaborative mathematics' BIBAKFull-Text 10
  Michael J. Barany
In February, 2009, an international group comprising mathematicians ranging from amateurs to elite professionals converged on the WordPress blog of Cambridge mathematician Timothy Gowers in order to attempt to prove a mathematical theorem -- a project Gowers called Polymath1. Their results surprised even the project's most optimistic participants. In six weeks, the group had managed to combinatorially prove the density Hales-Jewett theorem, yielding in the process a host of new mathematical insights.
   This paper explores how the mathematicians of Polymath1 worked within and adapted the WordPress blog environment to their uses. I examine from a qualitative sociological perspective how procedural and technical questions interacted in a mathematics research setting as the project moved from its nebulous beginnings toward completion. The paper thus indirectly considers the ways in which such meta-mathematical questions are inscribed in research environments, and opens up several methodological questions for the sociology of mathematics and the Internet. Between the mathematical and meta-mathematical negotiations of the Polymath1 project, there emerges a rich virtual site for the study of collaboration in mathematics and related disciplines.

A Wiki-based collective intelligence approach to formulate a body of knowledge (BOK) for a new discipline BIBAKFull-Text 11
  Yoshifumi Masunaga; Yoshiyuki Shoji; Kazunari Ito
This paper describes a wiki-based collective intelligence approach to provide a system environment that enables users to formulate a body of knowledge (BOK) for a new discipline, such as social informatics. When the targeted discipline is mature, for example, computer science, its BOK can be straightforwardly formulated by a task force using a top-down approach. However, in the case of a new discipline, it is presumed that nobody has a comprehensive understanding of it; therefore, the formulation of BOK in such a field can be carried out using a bottom-up approach. In other words, a collective intelligence approach supporting such work seems promising. This paper proposes the BOK+ which is a novel BOK formulation principle for new disciplines. To realize this principle, the BOK Constructor is designed and prototyped where Semantic MediaWiki (SMW) is used to provide its basic functions. The BOK Constructor consists of a BOK Editor, SMW, Uploader, and BOK Miner. Most of the fundamental functions of the BOK Constructor, with the exception of the BOK Miner, were implemented. We validated that the BOK Constructor serves its intended purpose.

What cognition does for Wikis BIBAKFull-Text 12
  Rut Jesus
Theoretical frameworks need to be developed to account for the phenomenon of Wikipedia and writing in Wikis. In this paper, a cognitive framework divides processes into the categories of Cognition for Planning and Cognition for Improvising. This distinction is applied to Wikipedia to understand the many small and the few big edits by which Wikipedia's articles grow. The paper relates the distinction to Lessig' Read-Only and Read-Write, to Benkler's modularity and granularity of contributions and to Turkle and Papert's bricoleurs and planners. It argues that Wikipedia thrives because it harnesses a Cognition for Improvising surplus oriented by kindness and trust towards distant others and proposes that Cognition for Improvising is a determinant mode for the success of Wikis and Wikipedia. The theoretical framework can be a starting point for a cognitive discussion of wikis, peer-produced commons and new patterns of collaboration.

Project management in the Wikipedia community BIBAKFull-Text 13
  Hang Ung; Jean-Michel Dalle
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.
Keywords: Wikipedia, leadership, online communities, project-based organizations

A taxonomy of Wiki genres in enterprise settings BIBAKFull-Text 14
  Erika Shehan Poole; Jonathan Grudin
A growing body of work examines enterprise wikis. In this paper, we argue that "enterprise wiki" is a blanket term describing three different genres of wiki: single contributor wikis, group or team wikis, and internal-use encyclopedias emulating Wikipedia. Based on the results of a study of wiki usage in a multinational software company, we provide a taxonomy of enterprise wiki genres. We discuss emerging challenges specific to company-wide encyclopedias for which platforms such as Wikipedia provide surprisingly little guidance. These challenges include platform and content management decisions, territoriality, establishment of contribution norms, dispute resolution, and employee turnover.

Toward sensitive information redaction in a collaborative, multilevel security environment BIBAKFull-Text 15
  Peter Gehres; Nathan Singleton; George Louthan; John Hale
Wikis have proven to be an invaluable tool for collaboration. The most prominent is, of course, Wikipedia. Its open nature is not suitable for all environments; in corporate, government, and research environments it is often necessary to control access to some or all of the information due to confidentially, privacy, or security concerns. This paper proposes a method by which information classified at multiple sensitivity levels can be securely stored and made accessible via the wiki only to authenticated and authorized users. The model allows for each page to be viewed at appropriate levels of classification transparently included or excluded based on the user's access level.
Keywords: collaboration, multilevel security, redaction


A fielded wiki for personality genetics BIBAKFull-Text 16
  Finn Årup Nielsen
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.

Spatio-temporal analysis of Wikipedia metadata and the STiki anti-vandalism tool BIBAFull-Text 18
  Andrew G. West; Sampath Kannan; Insup Lee
The bulk of Wikipedia anti-vandalism tools require natural language processing over the article or diff text. However, our prior work demonstrated the feasibility of using spatio-temporal properties to locate malicious edits. STiki is a real-time, on-Wikipedia tool leveraging this technique.
   The associated poster reviews STiki's methodology and performance. We find competing anti-vandalism tools inhibit maximal performance. However, the tool proves particularly adept at mitigating long-term embedded vandalism. Further, its robust and language-independent nature make it well-suited for use in less-patrolled Wiki installations.
A method for category similarity calculation in Wikis BIBAKFull-Text 19
  Cheong-Iao Pang; Robert P. Biuk-Aghai
Wikis, such as Wikipedia, allow their authors to assign categories to articles in order to better organize related content. This paper presents a method to calculate similarities between categories, illustrated by a calculation for the top-level categories in the Simple English version of Wikipedia.

Zawilinski: a library for studying grammar in Wiktionary BIBAKFull-Text 20
  Zachary Kurmas
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.

Chatting in the Wiki: synchronous-asynchronous integration BIBAKFull-Text 22
  Robert P. Biuk-Aghai; Keng Hong Lei
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.
Keywords: asynchronous, communication, instant messaging, synchronous, wiki
Collaborative modeling with semantic MediaWiki BIBAKFull-Text 23
  Frank Dengler; Hans-Jörg Happel
Modeling is an important aspect of information system development, allowing for abstract descriptions of systems and processes. Therefore, models are often characterized as communication artifacts between different stakeholders in a development process. However, modeling as such has turned out to be a specialist activity, requiring skills in arcane modeling languages and complex tools.
   In this paper, we suggest and present an approach for collaborative, Wiki-based modeling of process models and UML (class-)diagrams. While other web-based "lightweight" modeling tools are available, our approach consequently follows the Wiki-paradigm and allows us to semantically process the modeled information building upon Semantic MediaWiki.
Keywords: UML, modeling, process models, semantic Wikis
Wikipedia and the two-faced professoriate BIBAKFull-Text 24
  Patricia L. Dooley
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.
Keywords: Wikipedia, credibility, higher education, usage
Encouraging language students to contribute inflection data to Wiktionary BIBAKFull-Text 25
  Zachary Kurmas
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 to Wiktionary. 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.
Keywords: Wiktionary, inflection, language, wiki
"What i know is...": establishing credibility on Wikipedia talk pages BIBAKFull-Text 26
  Meghan Oxley; Jonathan T. Morgan; Mark Zachry; Brian Hutchinson
This poster presents a new theoretical framework and research method for studying the relationship between specific types of authority claims and the attempts of contributors to establish credibility in online, collaborative environments. We describe a content analysis method for coding authority claims based on linguistic and rhetorical cues in naturally occurring, text-based discourse. We present results from a preliminary analysis of a sample of Wikipedia talk page discussions focused on recent news events. This method provides a novel framework for capturing and understanding these persuasion-oriented behaviors, and shows potential as a tool for online communication research, including automated text analysis using trained natural language processing systems.
Keywords: computer-mediated communication, computer-supported cooperative work, sociotechnical systems, wikis
Learning about team collaboration from Wikipedia edit history BIBAKFull-Text 27
  Adam Wierzbicki; Piotr Turek; Radoslaw Nielek
This work presents an evaluation method of teams of authors in Wikipedia based on social network analysis. We have created an implicit social network based on the edit history of articles. This network consists of four dimensions: trust, distrust, acquaintance and knowledge. Trust and distrust are based on content modifications (copying and deleting respectively); acquaintance is based on the amount of discussion on articles' talk pages between a given pair of authors and knowledge is based on the categories in which an author typically contributes. As authors edit the Wikipedia, the social network grows and changes to take into account their collaboration patterns, creating a succinct summary of entire edit history.
Keywords: Wikipedia, collaboration, social networks


Reviewing and challenging socio-political approaches in the analysis of open collaboration and collective action online BIBAFull-Text 28
  Mayo Fuster Morell; Benjamin Mako Hill
Empirical research on open collaboration and collective action online has begun in earnest only recently. Different research approaches have emerged over the last decades that aim at explaining the socio-political base of open collaboration. The panel focuses on several key issues and challenges facing sociopolitical approaches in the analysis of open collaboration and collective action online, will attempt to map the main theoretical and methodological research trends, and finally, challenges the limitations and traps of current approaches while reflecting on the suitable ways to fruitfully analyses open collaboration.


Teaching with Wikipedia and other Wikimedia foundation wikis BIBAKFull-Text 29
  Piotr Konieczny
Wikipedia and other wikis operated by the Wikimedia Foundation are finding increasing applications in teaching and learning. This workshop will demonstrate how teachers from academia and beyond can use those wikis in their courses. Wikipedia can be used for various assignments: for example, students can be asked to reference an unreferenced article or create a completely new one. Students can also work on creating a free textbook on Wikibooks, learn about journalism on Wikinews or engage in variety of media-related projects on Commons. In doing so, students will see that writing an article and related assignments are not a 'tedious assignment' but activities that millions do 'for fun'. They will also gain a deeper understanding of what Wikipedia is, and how (un)reliable it can be. They and the course leaders are assisted by a lively, real world community. Last, but not least, their work will also benefit -- and be improved upon -- by the entire world.
   The workshop will focus on English Wikipedia, the most popular WMF wiki with regards to where the teaching assignments are taking place, but will also discuss the educational opportunities on other WMF wikis, such as Wikibooks. An overview of the Wikipedia School and University Project will be presented. There will be a discussion of Wikipedia policies related to teaching assignments, and a presentation of tools developed to make teaching with Wikipedia easier. The participants will see what kind of assignments can be done on Wikipedia (from learning simple wiki editing skills, through the assignments designed to teach students about proper referencing and sources reliability, to writing paper assignments with the goal of developing Good and Featured Articles), and how they can be implemented most easily and efficiently, avoiding common pitfalls and dealing with common problems (such as how to avoid having your students' articles deleted minutes after creation).
   Finally, the participants will be given an opportunity to create a draft syllabus for a future course they may want to teach on a WMF wiki (bringing your laptops for that part is highly recommended).

Engaging with open education BIBAKFull-Text 30
  Panagiota Alevizou; Andrea Forte
This panel will address key issues and provide empirically-grounded insights on learning about, with, and through open educational resources (OER). Open educational resources are educational materials that are freely shared by those who seek to learn and those who seek to teach. OERs are viewed by many as a revolutionary idea that could create more accessible, equitable education on a global scale; yet, the benefits and challenges of OER adoption in practice are not yet understood. Many OER initiatives are pursuing a vision of education as a 'public good', and international policy agendas on education are shifting from the idea of simply providing access to content, towards the notion of creating 'Open Participatory Learning Ecosystems'; these efforts have outpaced our understanding of how educational systems behave when they become more open. Open education requires further empirical investigation. Each of the individuals on this panel brings expertise that speaks not only to understanding the potential value of OER, but also to understanding barriers and challenges of OER adoption. Speakers will cover issues on:
  • Advocacy, policy & development of OER
  • Social interfaces and the design of participation
  • Mentoring and peer learning in Open Education environments
  • Popular perceptions about OER, and attitudes towards sharing and creating OER

    STiki: an anti-vandalism tool for Wikipedia using spatio-temporal analysis of revision metadata BIBAFull-Text 32
      Andrew G. West; Sampath Kannan; Insup Lee
    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 classification (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.

    Doctoral symposium

    Wikisym doctoral symposium: introduction and summary of contributions BIBAFull-Text 35
      Kevin Crowston
    The WikiSym 2010 Doctoral Symposium was held immediately after WikiSym and offered invited Ph.D. students an unparalleled opportunity to present their ongoing work on wikis and open collaboration research. Students received supportive feedback from their peers and a panel of faculty mentors, to help them envision new, added-value contributions to their current research. The symposium also offered a perfect environment for the exchange of information, methodologies, practical experiences and advice that may help Ph.D. students on their way, unleashing potential interactions and opportunities for collaboration.
