| When a wiki is not a wiki: twenty years of the Victorian Web: keynote | | BIBA | Full-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 | | BIBA | Full-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 | | BIBA | Full-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. | |||

| Getting started with XWiki | | BIBA | Full-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 | | BIBA | Full-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). | |||

| LBWiki: a location-based Wiki | | BIBAK | Full-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 | | BIBAK | Full-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,

| ShyWiki-A spatial hypertext wiki | | BIBAK | Full-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 | | BIBAK | Full-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. Keywords: collaborative knowledge building, concept mapping, design-based research,

| Translating the DEMGOL etymological dictionary of Greek Mythology with the BEYTrans wiki | | BIBAK | Full-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). Keywords: CAT, DEMGOL, XML, collaborative translation, computer-assisted translation,

| The Cross-Lingual Wiki Engine: enabling collaboration across language barriers | | BIBAK | Full-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. Keywords: Tiki-Wiki CMS/groupware, collaborative translation, cross-lingual
collaboration, cross-lingual wiki engine, multilingual change tracking, wiki | |||
| wikiBABEL: community creation of multilingual data | | BIBAK | Full-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.

| Measuring author contributions to the Wikipedia | | BIBA | Full-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 | | BIBAK | Full-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. Keywords: analysis, co-authorship, wiki | |||
| A study of ontology convergence in a semantic Wiki | | BIBAK | Full-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. Keywords: Semantic Web, Semantic Wiki, emergent ontologies | |||
| Motivating and enabling organizational memory with a workgroup wiki | | BIBAK | Full-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. Keywords: knowledge exchange, knowledge transfer, organizational memory,

| Visualizing wiki-supported knowledge building: co-evolution of individual and collective knowledge | | BIBAK | Full-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. Keywords: co-evolution, collective knowledge, knowledge building, visualization, wikis | |||
| Wiki-based collaborative learning: incorporating self-assessment tasks | | BIBAK | Full-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.

| A grammar for standardized wiki markup | | BIBAK | Full-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. Keywords: wiki creole, wiki engine performance, wiki markup, wiki markup grammar, wiki
markup parser, wiki markup standard, wiki markup test cases, wikis | |||
| A bliki model to support political discourse formation | | BIBAK | Full-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. Keywords: bliki, blog, deliberative democracy, discourse formation, public

| Security of community developed and 3rd-party wiki plug-ins | | BIBAK | Full-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 trust metrics based on phrasal analysis | | BIBAK | Full-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 | | BIBA | Full-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 | | BIBA | Full-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 | | BIBAK | Full-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. Keywords: dynamics, governance, metrics, moderation, online communities, viability,

| 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. Keywords: agile development, blended learning, wikis | |||

| Wikideas and creativity connector: supporting group ideational creativity | | BIBA | Full-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. | |||

| 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. Keywords: Wikipedia, quantitative analysis, request characterization, temporal

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.

| ShyWiki: a spatial hypertext wiki prototype | | BIBAK | Full-Text | 36 | |
| Carlos Solís; Nour Ali | |||
| This paper presents ShyWiki, a Spatial Hypertext Wiki. ShyWiki has the
flexibility and advantages of spatial hypertext. Hypertext documents in ShyWiki
are composed of notes and maps that can be arranged by users. 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. Keywords: hypertext, spatial hypertext, wiki | |||
| Workshop on interdisciplinary research on Wikipedia and wiki communities | | BIBAK | Full-Text | 37 | |

| 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". Keywords: Wikipedia, collaboration, interdisciplinary, methodologies, wiki

| Babel wiki workshop: cross-language collaboration | | BIBAK | Full-Text | 38 | |

| 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. Keywords: collaborative translation, cross-lingual collaboration, wiki | |||
| Wikis4SE'2008: wikis for software engineering | | BIBAK | Full-Text | 39 | |

| 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. Keywords: collaboration, documentation, software development, wikis, wikis for
