When a wiki is not a wiki: twenty years of the Victorian Web: keynote BIBAFull-Text 1
  George P. Landow
All the chatter and puffery about Web 2.0 reminds those who have worked several decades in related fields of computing that the World Wide Web is essentially Hypertext 0.5: Ted Nelson, Vannevar Bush, Douglas Englebart, Andries van Dam, and other pioneering hypertext theorists all emphasized that true hypertext has to have to allow readers to write and link. Fortunately, with the coming of blogs and now wikis, the Web has at last begun to approach the vision of the hypertext pioneers. Therefore, after a brief look at the most useful paradigms for wikis -- that is, the best way for readers and writers to think about them -- we shall look at The Victorian Web, a site containing more than 38,000 documents and images, some of which date from 1988 -- long before the WWW took its present form. The four pre-web versions of the site used both full and partial read-write systems, and as the site took form, its webmaster and editors tried to employ the lessons learned from the earlier hypermedia systems to the WWW. We shall therefore look at how portions of the site have turned out to function much like a proto-wiki -- a dynamic hypermedia corpus that contributors continually grow -- and what kind of lessons the experience of working with the site has for owners and contributors of wikis.
The Lively Kernel: a wiki of active objects: invited talk BIBAFull-Text 2
  Dan Ingalls
The Lively Kernel is a complete platform for Web programming written in JavaScript using graphics available in leading browsers. A widget set built from these elements provides a user interface kit, and the widget set is also extensible. A window-based IDE allows users to edit their applications and even the system itself.
Application wikis to mashup makers to next generation mashups: keynote BIBAFull-Text 3
  Stewart Nickolas
In this session we'll discuss our experiences and lessons learned over the past couple years from developing and validating a technology called QEDWiki which is an application wiki (see video). We will also discuss our vision of the web beyond the technologies, uses and concepts attributed to Web 2.0. We'll discuss the importance of the ecosystem at the heart of the mashup/application wiki ecosystem, specifically, opensource, commercial and community efforts. Looking forward, we'll explore ways to derive new value from web consumables such as text, video and audio using semantic analysis and the inspection and repurposing of huge amounts of data within "massive" mashups.

End-user programming with application wikis BIBAFull-Text 4
  Ludovic Dubost; Stewart Nickolas; Peter Thoeny; Dirk Riehle
Wikis empower users to collaborate with each other using prose. Users imprint data structures and processes onto wiki pages using social and technical conventions.

Tutorials

Getting started with XWiki BIBAFull-Text 5
  Ludovic Dubost; Guillaume Lerouge
There are several wikis out there, from the widely popular MediaWiki to less-known alternatives such as GeboGebo or Sycamore. So many of them in fact, that most people cannot really distinguish one from another. While offering all the features wiki users have come to get used to (easy edition, page history, rich text editor), XWiki stands out as one of the few application wikis currently available. This tutorial will explain how one can go all the way from creating a simple XWiki-based website to writing small business applications right into the wiki.
TikiWiki CMS/groupware: when a Wiki is not enough BIBAFull-Text 6
  Marc Laporte
TikiWiki is a powerful, multilingual Wiki, Content Management System (CMS) and Groupware. Translated to 35 languages, and with an install base of tens of thousands, over 200 people have contributed to the source code and it provides hundreds of built-in features to create all sorts of web sites, intranets and extranets. The community eats its own DogFood and applies the "Wiki Way" to software development. Written in PHP, it is released as free software (LGPL).

Innovative wikis

LBWiki: a location-based Wiki BIBAKFull-Text 8
  David E. Millard; Rebecca Lewis; Yvonne Howard
Wiki systems provide a simple interface paradigm that allow non-technical users to author collaborative on-line hypertexts. In this paper we propose to use the same simple paradigm to allow users to create content for ubiquitous information systems, and present LBWiki, a prototype location-based Wiki that allows users with a mobile device to create Wiki pages based on GPS co-ordinates. We describe the hierarchical location scheme used within LBWiki and the results of a small evaluation, in which users reacted positively to the concept, but asked for greater control over geographical regions, and highlighted the importance of accurate location technology.
Keywords: location-based systems, physical hypertext
Socs: increasing social and group awareness for Wikis by example of Wikipedia BIBAKFull-Text 9
  Claus Atzenbeck; David L. Hicks
Many wikis provide good workspace awareness. Users see quickly what changes have been made or get notified about modifications on selected pages. However, they do not support a more sophisticated social or group awareness.
   Being aware of social structures is important for collaborative work. Adequate tools permit team members to reflect upon their and others' roles, detect and solve related conflicts in good time, and provide a means to communicate team developments. This makes such applications an effective means for new collaborators (to understand the team), long term team members (to see what is going on), and team coordinators (to manage teams and identify potential problems). This becomes especially important for fragile, large, or ad hoc virtual teams as we find around many wikis, such as Wikipedia. Furthermore, we argue that social and group awareness increases the quality of articles indirectly and is beneficial for both experts and novice users.
   We introduce Socs, a prototype that permits authoring social structures using spatial hypertext methods via a so-called "social space". It serves as a means to express, store, and communicate social information about people, such as wiki authors. Furthermore, Socs integrates a Web browser and the system-wide address book that act as sources for the social space and as a basis for sophisticated awareness services.
   Socs provides awareness about the authors of a wiki page and which of them are part of the user's structure on the social space, those that are of special interest to the user. This creates implicitly recommendations about wiki pages (because users get notified when wiki pages are authored by known people), provides the basis of interpreting the authors' intentions (because users become aware of who wrote the articles), and foster communication (because users may want to discuss those article with whom they know).
Keywords: Socs, Web 2.0, Wikipedia, collaboration, coordination, group awareness, hypermedia, social awareness, wiki
ShyWiki-A spatial hypertext wiki BIBAKFull-Text 10
  Carlos Solís; Nour Ali
This paper presents ShyWiki, a Spatial Hypertext Wiki. ShyWiki has the flexibility and advantages of spatial hypertext. ShyWiki hypertext documents are composed of notes and maps that can be arranged by users. Users can change the spatial attributes of the elements in a hypertext document such as their position, order, color, size, etc. Furthermore, users can move, delete or aggregate notes as well as maps. ShyWiki allows users to perform a collaborative spatial hypertext design due to the fact that the community of users decide the final structure of a wiki page.
Keywords: hypertext, spatial hypertext, wiki
ThinkSpace: the collaborative process of designing new technologies for the classroom BIBAKFull-Text 11
  Jane Alexen Shuyska; Chris Davies
In order to explore some of the potentially problematic implications of introducing new technologies into school classrooms, this paper focuses on one particular instance of innovation. The study introduces ThinkSpace -- a specific educational tool -- comprised of concept mapping and a wiki. It is aimed at facilitating the learning of higher order skills and construction of coherent understanding of complex concepts. The paper investigates the processes of conceptualisation and experimentation that must be carried out in order to achieve a product that meets both the developer's aspirations for the tool, and also those of the teacher who is to use it.

Wiki and language

Translating the DEMGOL etymological dictionary of Greek Mythology with the BEYTrans wiki BIBAKFull-Text 12
  Youcef Bey; Kyo Kageura; Christian Boitet; Francesca Marzari
BEYTrans (Better Environment for Your TRANSlation) is a generic Wiki tool designed to support communities of volunteer translators not only by offering them an online translation editor and helps to manage the translation progress, but a complete online computer-assisted translation (CAT) environment including a translation editor, translation memories, free dictionaries, automatic calls to machine translation (MT) systems, and support to collaborative volunteer translation. We present the basic concepts of BEYTrans and its experimentation on the translation from Italian to French of the DEMGOL project (OnLine Etymological Dictionary of the Greek Mythology).

The Cross-Lingual Wiki Engine: enabling collaboration across language barriers BIBAKFull-Text 13
  Louis-Philippe Huberdeau; Sébastien Paquet; Alain Désilets
In this paper, we present the Cross-Lingual Wiki Engine (CLWE), a system designed to support concurrent, collaborative authoring and translation of content in multiple languages. We start by showing how collaborative translation differs from conventional translation environments. In particular, we show how conventional industrial translation processes and tools are based on assumptions that often do not hold in collaborative environments. We then provide a detailed storyboard which shows how the CLWE can be used by groups of users, to collaboratively author and translate content without having to make those assumptions. We then discuss the implementation of the CLWE's change tracking infrastructure, which turns out to be the critical component in enabling this sort of open-ended translation workflow. We show how the problem of tracking changes in multiple languages at once can be greatly simplified using abstract change tokens which are independent of language and textual content. The system has been deployed in several communities, including SUMO (the Firefox documentation site), and preliminary feedback is encouraging.

wikiBABEL: community creation of multilingual data BIBAKFull-Text 14
  A. Kumaran; K. Saravanan; Sandor Maurice
In this paper, we present a collaborative framework -- wikiBABEL -- for the efficient and effective creation of multilingual content by a community of users. The wikiBABEL framework leverages the availability of fairly stable content in a source language (typically, English) and a reasonable and not necessarily perfect machine translation system between the source language and a given target language, to create the rough initial content in the target language that is published in a collaborative platform. The platform provides an intuitive user interface and a set of linguistic tools for collaborative correction of the rough content by a community of users, aiding creation of clean content in the target language. We describe the architectural components implementing the wikiBABEL framework, namely, the systems for source and target language content management, mechanisms for coordination and collaboration and intuitive user interface for multilingual editing and review. Importantly, we discuss the integrated linguistic resources and tools, such as, bilingual dictionaries, machine translation and transliteration systems, etc., to help the users during the content correction and creation process. In addition, we analyze and present the prime factors -- user-interface features or linguistic tools and resources -- that significantly influence the user experiences in multilingual content creation.
   In addition to the creation of multilingual content, another significant motivation for the wikiBABEL framework is the creation of parallel corpora as a by-product. Parallel linguistic corpora are very valuable resources for both Statistical Machine Translation (SMT) and Crosslingual Information Retrieval (CLIR) research, and may be mined effectively from multilingual data with significant content overlap, as may be created in the wikiBABEL framework. Creation of parallel corpora by professional translators is very expensive, and hence the SMT and CLIR research have been largely confined to a handful of languages. Our attempt to engage the large and diverse Internet user population may aid creation of such linguistic resources economically, and may make computational linguistics research possible and practical in many languages of the world.

Wiki writers

Measuring author contributions to the Wikipedia BIBAFull-Text 15
  B. Thomas Adler; Luca de Alfaro; Ian Pye; Vishwanath Raman
We consider the problem of measuring user contributions to versioned, collaborative bodies of information, such as wikis. Measuring the contributions of individual authors can be used to divide revenue, to recognize merit, to award status promotions, and to choose the order of authors when citing the content. In the context of the Wikipedia, previous works on author contribution estimation have focused on two criteria: the total text created, and the total number of edits performed. We show that neither of these criteria work well: both techniques are vulnerable to manipulation, and the total-text criterion fails to reward people who polish or re-arrange the content.
   We consider and compare various alternative criteria that take into account the quality of a contribution, in addition to the quantity, and we analyze how the criteria differ in the way they rank authors according to their contributions. As an outcome of this study, we propose to adopt total edit longevity as a measure of author contribution. Edit longevity is resistant to simple attacks, since edits are counted towards an author's contribution only if other authors accept the contribution. Edit longevity equally rewards people who create content, and people who rearrange or polish the content. Finally, edit longevity distinguishes the people who contribute little (who have contribution close to zero) from spammers or vandals, whose contribution quickly grows negative.
A method for measuring co-authorship relationships in MediaWiki BIBAKFull-Text 16
  Libby Veng-Sam Tang; Robert P. Biuk-Aghai; Simon Fong
Collaborative writing through wikis has become increasingly popular in recent years. When users contribute to a wiki article they implicitly establish a co-authorship relationship. Discovering these relationships can be of value, for example in finding experts on a given topic. However, it is not trivial to determine the main co-authors for a given author among the potentially thousands who have contributed to a given author's edit history. We have developed a method and algorithm for calculating a co-authorship degree for a given pair of authors. We have implemented this method as an extension for the MediaWiki system and demonstrate its performance which is satisfactory in the majority of cases. This paper also presents a method of determining an expertise group for a chosen topic.

A study of ontology convergence in a semantic Wiki BIBAKFull-Text 17
  Chrysovalanto Kousetti; David E. Millard; Yvonne Howard
Semantic Wikis propose a combination of both easy collaboration and semantic expressivity; characteristics of the WikiWikiWeb and the Semantic Web respectively. In this paper we look to define and analyse the Semantic Wiki method, in order to explore the effect of different Semantic Wiki characteristics on the quality of the semantic networks authored within them. We look at a number of different Semantic Wiki implementations, including their semantic expressivity and usability. We focus on support for ontology creation, and perform an evaluation on the effect of type suggestion tools on ontology convergence within a seeded and unseeded Wiki (using Semantic MediaWiki and our own MOCA extension). We find that seeding a Wiki with typed pages and links has a strong effect on the quality of the emerging structure and that convergence tools have the potential to replicate that effect with an unseeded Wiki, but that they have limited impact on the reuse of elements from the evolving ontology.

Knowledge representation and learning

Motivating and enabling organizational memory with a workgroup wiki BIBAKFull-Text 18
  Sean A. Munson
Workgroups can struggle with remembering past projects and sharing this information with other groups in the organization. In a case study of the deployment of MediaWiki as a publishing tool for building organizational memory, group members' motivation to document past projects increased. A browsable collection of past projects allowed for discovery of past work, building the reputation of individuals and the workgroup, and development of transactive memory within the workgroup. The "anyone can edit" feature, frequently touted as the main benefit of wikis, had both benefits and drawbacks in this implementation. Group members did not feel comfortable making substantial edits to others' content but did occasionally use the wiki to coauthor content and also categorize and link to others' content and fix typos, particularly when asked to help.

Visualizing wiki-supported knowledge building: co-evolution of individual and collective knowledge BIBAKFull-Text 19
  Andreas Harrer; Johannes Moskaliuk; Joachim Kimmerle; Ulrike Cress
It is widely accepted that wikis are valuable tools for successful collaborative knowledge building. In this paper, we describe how processes of knowledge building with wikis may be visualized, citing Wikipedia as an example. The underlying theoretical basis of our paper is the framework for collaborative knowledge building with wikis, as introduced by Cress and Kimmerle [2], [3], [4]. This model describes collaborative knowledge building as a co-evolution of individual and collective knowledge, or of cognitive and social systems respectively. These co-evolutionary processes may be visualized graphically, applying methods from social network analysis, especially those methods that take dynamic changes into account [5], [18]. For this purpose, we have undertaken to analyze, on the one hand, the temporal development of an article in the German version of Wikipedia and related articles that are linked to this core article. On the other hand, we analyzed the temporal development of those users who worked on these articles. The resulting graphics show an analogous process, both with regard to the articles that refer to the core article and to the users involved. These results provide empirical support for the co-evolution model. Some implications of our findings and the potential for future research on collaborative knowledge building with wikis and on the application of social network analysis are discussed at the end of the article.

Wiki-based collaborative learning: incorporating self-assessment tasks BIBAKFull-Text 20
  Ben Liu; Hejie Chen; Wei He
When assigning technological articles as the collaborative writing task, students may find that the available knowledge repositories leave little room for them to contribute and therefore write nothing. To provide guidelines for students to discover topics, as well as tools to practice problem solving skills, we integrated a computer assisted assessment module into the Mediawiki and employ self-tests as the collaborative tasks. In these task, item models are used to automatically generate test questions. The items deriving from a same model share a common structure; however, the randomly initialized parameters of the model make them differ from each other. These differences result in that the answers of an item are usually inapplicable to other items deriving from the same model. Therefore, examinees have to solve these generated items on a case by case basis. Further, how to solve questions deriving from certain models can be served as the topics about which students write articles.
   The wiki self-assessment system was used in a course on Computer Networks offered to junior students majored in computer science. Five self-test tasks were assigned to 98 students, and they were encouraged to write wiki pages to explain their solution methods. Evidence from this preliminary application indicates that the presented approach has a positive effect on learning outcomes.

Models, architecture, and other vexations

A grammar for standardized wiki markup BIBAKFull-Text 21
  Martin Junghans; Dirk Riehle; Rama Gurram; Matthias Kaiser; Mário Lopes; Umit Yalcinalp
Today's wiki engines are not interoperable. The rendering engine is tied to the processing tools which are tied to the wiki editors. This is an unfortunate consequence of the lack of rigorously specified standards. This paper discusses an EBNF-based grammar for Wiki Creole 1.0, a community standard for wiki markup, and demonstrates its benefits. Wiki Creole is being specified using prose, so our grammar revealed several categories of ambiguities, showing the value of a more formal approach to wiki markup specification. The formalization of Wiki Creole using a grammar shows performance problems that today's regular-expression-based wiki parsers might face when scaling up. We present an implementation of a wiki markup parser and demonstrate our test cases for validating Wiki Creole parsers. We view the work presented in this paper as an important step towards decoupling wiki rendering engines from processing tools and from editing tools by means of a precise and complete wiki markup specification. This decoupling layer will then allow innovation on these different parts to proceed independently and as is expected at a faster pace than before.

A bliki model to support political discourse formation BIBAKFull-Text 22
  Rui Pedro Lourenço
This paper presents a bliki model which combines the potential of a blog and a wiki in order to support the creation of a constellation of political discourses in the public sphere and promote critical reflection among them. The model is inspired on traditional local public participation events that usually take the form of a face-to-face meeting where participants discuss some issue or problem and, in the end, produce a document summarizing the highlights of the event.
   The model embraces the collaborative paradigm fostered by the Internet and tries to support the creation of a set of documents (using a wiki), each one representing a particular discourse, whose content is generated from the discussion held in a blog. It is based on the identification of relevant ideas expressed in the blog, which are then sorted according to the point of view (discourse) they support, and are incorporated into the wiki document representing that discourse by those participants supporting it.

Security of community developed and 3rd-party wiki plug-ins BIBAKFull-Text 23
  Andy Webber
This paper discusses the significant security vulnerabilities that can occur in community developed wiki plug-ins and issues associated with managing the process of remediation. General guidance is given on how the vulnerabilities can be detected and rectified.
   The basis for the paper is direct experience with a number of community developed plug-ins for DokuWiki, although the findings have also been transferred to other wikis such as MediaWiki. The findings are also transferable to other similar web server technologies -- such as blogs -- that support similar plug-in frameworks.

Wiki analysis, growth, and trust

Wiki trust metrics based on phrasal analysis BIBAKFull-Text 24
  Mark Kramer; Andy Gregorowicz; Bala Iyer
Wiki users receive very little guidance on the trustworthiness of the information they find. It is difficult for them to determine how long the text in a page has existed, or who originally authored the text. It is also difficult to assess the reliability of authors contributing to a wiki page. In this paper, we create a set of trust indicators and metrics derived from phrasal analysis of the article revision history. These metrics include author attribution, author reputation, expertise ratings, article evolution, and text trustworthiness. We also propose a new technique for collecting and maintaining explicit article ratings across multiple revisions.
Keywords: attribution, authorship, collaboration, reputation, shingling, wiki
WikiChanges: exposing Wikipedia revision activity BIBAFull-Text 25
  Sérgio Nunes; Cristina Ribeiro; Gabriel David
Wikis are popular tools commonly used to support distributed collaborative work. Wikis can be seen as virtual scrap-books that anyone can edit without having any specific technical know-how. The Wikipedia is a flagship example of a real-word application of wikis. Due to the large scale of Wikipedia it's difficult to easily grasp much of the information that is stored in this wiki. We address one particular aspect of this issue by looking at the revision history of each article. Plotting the revision activity in a timeline we expose the complete article's history in a easily understandable format. We present WikiChanges, a web-based application designed to plot an article's revision timeline in real time. WikiChanges also includes a web browser extension that incorporates activity sparklines in the real Wikipedia. Finally, we introduce a revisions summarization task that addresses the need to understand what occurred during a given set of revisions. We present a first approach to this task using tag clouds to present the revisions made.
Assigning trust to Wikipedia content BIBAFull-Text 26
  B. Thomas Adler; Krishnendu Chatterjee; Luca de Alfaro; Marco Faella; Ian Pye; Vishwanath Raman
The Wikipedia is a collaborative encyclopedia: anyone can contribute to its articles simply by clicking on an "edit" button. The open nature of the Wikipedia has been key to its success, but has also created a challenge: how can readers develop an informed opinion on its reliability? We propose a system that computes quantitative values of trust for the text in Wikipedia articles; these trust values provide an indication of text reliability.
   The system uses as input the revision history of each article, as well as information about the reputation of the contributing authors, as provided by a reputation system. The trust of a word in an article is computed on the basis of the reputation of the original author of the word, as well as the reputation of all authors who edited text near the word. The algorithm computes word trust values that vary smoothly across the text; the trust values can be visualized using varying text-background colors. The algorithm ensures that all changes to an article's text are reflected in the trust values, preventing surreptitious content changes.
   We have implemented the proposed system, and we have used it to compute and display the trust of the text of thousands of articles of the English Wikipedia. To validate our trust-computation algorithms, we show that text labeled as low-trust has a significantly higher probability of being edited in the future than text labeled as high-trust.
Measuring wiki viability: an empirical assessment of the social dynamics of a large sample of wikis BIBAKFull-Text 27
  Camille Roth; Dario Taraborelli; Nigel Gilbert
This paper assesses the content- and population-dynamics of a large sample of wikis, over a timespan of several months, in order to identify basic features that may predict or induce different types of fate. We analyze and discuss, in particular, the correlation of various macroscopic indicators, structural features and governance policies with wiki growth patterns. While recent analyses of wiki dynamics have mostly focused on popular projects such as Wikipedia, we suggest research directions towards a more general theory of the dynamics of such communities.

Agile learning & teaching with wikis: building a pattern BIBAKFull-Text 28
  Marija Cubric
In this paper, we describe a blended learning process that is based on the agile development principles [1] and techniques [2] and supported by wikis. The process presented here is applicable to any learning and teaching scenario where the module objectives require development of non-cognitive skills such as: teamwork, giving and receiving feedback, collaborative writing, incremental and iterative development etc We believe that understanding agile principles and being able to apply agile techniques to any development activity are highly relevant skills that are important for the employability of our students.

Implementation of a wiki intranet in a health sector research institute BIBAKFull-Text 30
  Katja Hilska
A wiki can be one of the solutions when organization is looking for an intranet that supports internal communication and collaboration. This was realized in a health sector research institute seeking a solution to replace its former, very static and centrally managed, intranet with a more user-friendly and collaboration oriented intranet solution. This poster briefly describes the wiki-intranet project from the choosing and launching of the intranet to the first user survey.

Wikideas and creativity connector: supporting group ideational creativity BIBAFull-Text 31
  Oscar Ardaiz; Maria Luisa Sanz de Acedo; Maria Teresa Sanz de Acedo
In Ideation2.0 project [1] we are researching, developing and testing Web2.0 technologies to support group ideational creativity. We use wiki technologies in Wikideas tool to allow brainstorming sessions that gather large number of ideas which can be visualized later by other group members, thus enabling the generation of new ideas. Creativity Connector is a tool that is integrated with Wikideas and whose mission is to connect anonymous users into brainstorming groups to produce a greater number of innovative and original ideas. We consider that with their utilization will reduce participants apprehension to be evaluated and will bring about a significant improvement in group ideacional creativity. The assessment of these tools has been carried out in a study with a sample of 50 university students of software engineering and social worker degrees.
Multilingual idioms and proverbs: wiki as a tool in collaborative translation BIBAKFull-Text 32
  Dora Montagna
This work aims to provide a useful tool to translators, linguists and students who want to study and find equivalences of idioms and proverbs in different languages. The goal is to create an extensive multi-word expressions and proverbs corpus, overcoming the main problem of their classification, thanks to hypertext and key-word based search: a synthesis of a glossary and a forum, easily consulted; open to each external contribution, in regard to the changeable nature of such linguistic heritage.

  Raquel Frisa; Rosana Anglés; Óscar Puyal
This paper describes a feasible way to integrate Wiki-based projects with the access from mobile devices, in order to contribute to the convergence between Internet Services in the new mobile telecommunications space.
   Vodafone R&D, as one of the leading telecommunications operators, launches this initiative due to the social phenomenon Wikipedia, supported by the Wikimedia Foundation, has meant for the Internet community. This is the most successful project based on a wiki environment and thanks to it, collaborative tools like wikis have become in the perfect artifact to spread the knowledge across the Internet. Additionally, we contribute to the creation of open tools to access contents published under a free content license.

Quantitative analysis and characterization of Wikipedia requests BIBAKFull-Text 34
  Antonio J. Reinoso; Jesus M. Gonzalez-Barahona; Felipe Ortega; Greogrio Robles
Our poster describes the quantitative analysis carried out to study the use of the Wikipedia system by its users with special focus on the identification of time and kind-of-use patterns, characterization of traffic and workload, and comparative analysis of different language editions. By filtering and classifying a large sample of the requests directed to the Wikimedia systems over 7 days we have been able to identify important information such us the targeted namespaces, the visited resources or the requested actions. The results found include the identification of weekly and daily patterns, and several correlations between different actions on the articles. In summary, the study shows an overall picture of how the most visited language editions of the Wikipedia are being accessed by their users.

WikiSim: simulating knowledge collection and curation in structured wikis BIBAKFull-Text 35
  Luna De Ferrari; Stuart Aitken; Jano van Hemert; Igor Goryanin
The aim of this work is to model quantitatively one of the main properties of wikis: how high quality knowledge can emerge from the individual work of independent volunteers. The approach chosen is to simulate knowledge collection and curation in wikis.
   The basic model represents the wiki as a set of of true/false values, added and edited at each simulation round by software agents (users) following a fixed set of rules. The resulting WikiSim simulations already manage to reach distributions of edits and user contributions very close to those reported for Wikipedia. WikiSim can also span conditions not easily measurable in real-life wikis, such as the impact of various amounts of user mistakes.
   WikiSim could be extended to model wiki software features, such as discussion pages and watch lists, while monitoring the impact they have on user actions and consensus, and their effect on knowledge quality. The method could also be used to compare wikis with other curation scenarios based on centralised editing by experts. The future challenges for WikiSim will be to find appropriate ways to evaluate and validate the models and to keep them simple while still capturing relevant properties of wiki systems.

Users can change the spatial/visual attributes of the notes in the wiki pages such as their position, order, color, size, etc. Furthermore, users can move, delete or aggregate notes as well as maps. ShyWiki allows users to perform a collaborative spatial hypertext design due to the fact that the community of users decides the final structure of a wiki page.

Workshops

Workshop on interdisciplinary research on Wikipedia and wiki communities BIBAKFull-Text 37
  Felipe Ortega; Joseph Reagle; Antonio J. Reinoso; Rut Jesus
A growing number of projects seek to build upon the collective intelligence of Internet users, looking for more dynamic, open and creative approaches to content creation and knowledge sharing. To this end, many projects have chosen the wiki, and it is therefore the subject of much research interest, particularly Wikipedia, from varied disciplines. The array of approaches to study wikis is a source of wealth, but also a possible source of confusion: What are appropriate methodologies for the analysis of wiki communities? Which are the most critical parameters (both quantitative and qualitative) for study in wiki evolution and outcomes? Is it possible to find effective interdisciplinary approaches to augment our overall understanding of these dynamic, creative environments? This workshop intends to provide an opportunity to explore these questions, by researchers and practitioners willing to participate in a "brainstorming research meeting".

The Internet has by now become a truly global and multilingual community: non-English speakers presently account for two-thirds of Internet users. Yet, while dozens of languages are being used simultaneously on the same network, the language barriers make it difficult for connection and collaboration to happen across languages.

Wikis4SE'2008: wikis for software engineering BIBAKFull-Text 39
  Ademar Aguiar; Paulo Merson; Uri Dekel
The use of wikis in software engineering dates back to 1995, when Ward Cunningham created the first ever wiki as a platform for discussing patterns and software development efforts. The simplicity and effectiveness of wikis as a medium for collaborative authoring has lead to their vast popularity across many domains. The Wikis for Software Engineering (Wikis4SE) workshop aims at bringing together researchers, practitioners, and enthusiasts interested in exploring the potential of wikis as an effective tool to support software engineering activities. It serves as a forum for presenting new ideas and tools, and reporting on experiences, best practices, and newly discovered problems. Based on lessons learned and obstacles identified, a research agenda will be defined with key opportunities and challenges.
