| Visualizing the inner lives of texts | | BIBA | Full-Text | PDF | 1 | |
| Fernanda Viégas; Martin Wattenberg | |||
| Visualization is often viewed as a way to unlock the secrets of numeric data. But what about political speeches, novels, and blogs? These texts hold at least as many surprises. On the Many Eyes site, a place for collective visualization, we have seen an increasing appetite for analyzing documents. We present a series of techniques for visualizing and analyzing unstructured text. We also discuss how a technique developed for visualizing the authoring patterns of Wikipedia articles has recently revealed the collective lives of a much broader class of documents. | |||
| Community performance optimization: making your people run as smoothly as your site | | BIBA | Full-Text | PDF | 2 | |
| Brion Vibber | |||
| Collaborative communities such as those building wikis and open source software often discover that their human interactions have just as many scaling problems as their web infrastructure. As the number of people involved in a project grows, key decision-makers often become bottlenecks, and community structure needs to change or a project can become stalled despite the best intentions of all participants. I'll describe some of the community scaling challenges in both Wikipedia's editor community and the development of its underlying MediaWiki software and how we've overcome -- or are still working to overcome -- decision-making bottlenecks to "maximize community throughput". | |||
| Understanding learning: the Wiki way | | BIBAK | Full-Text | PDF | 3 | |
| Joachim Kimmerle; Johannes Moskaliuk; Ulrike Cress | |||
| Learning "the wiki way", learning through wikis is a form of self-regulated
learning that is independent of formal learning settings and takes place in a
community of knowledge. Such a community may work jointly on a digital artifact
to create new, innovative and emergent knowledge. We regard wikis as a
prototype of tools for community-based learning, and point out five relevant
features. We will present the co-evolution model, as introduced by Cress and
Kimmerle [3][4], that may be understood as a framework to describe learning in
the wiki way. This model describes collaborative knowledge building as a
co-evolution between cognitive and social systems. To investigate learning the
wiki way, we have to consider both individual processes and processes within
the wiki, which represent the processes that are going on within a community.
This paper presents three empirical studies that investigate learning the wiki way in a laboratory setting. We take a look at participants' contributions to a wiki indicating processes within the wiki community, and measure the extent of individual learning at the end of the experiment. Our conclusion is that the model of co-evolution has a strong impact on understanding learning the wiki way, may be helpful to designers of learning environments, and serve as framework for further research.

| rv you're dumb: identifying discarded work in Wiki article history | | BIBAK | Full-Text | PDF | 4 | |
| Michael D. Ekstrand; John T. Riedl | |||
| Wiki systems typically display article history as a linear sequence of
revisions in chronological order. This representation hides deeper
relationships among the revisions, such as which earlier revision provided most
of the content for a later revision, or when a revision effectively reverses
the changes made by a prior revision. These relationships are valuable in
understanding what happened between editors in conflict over article content.
We present methods for detecting when a revision discards the work of one or
more other revisions, a means of visualizing these relationships in-line with
existing history views, and a computational method for detecting discarded
work. We show through a series of examples that these tools can aid mediators
of wiki content disputes by making salient the structure of the ongoing
conflict. Further, the computational tools provide a means of determining
whether or not a revision has been accepted by the community of editors
surrounding the article. Keywords: Wiki, Wikipedia, article history, visualization | |||
| Bipartite networks of Wikipedia's articles and authors: a meso-level approach | | BIBAK | Full-Text | PDF | 5 | |
| Rut Jesus; Martin Schwartz; Sune Lehmann | |||
| This exploratory study investigates the bipartite network of articles linked
by common editors in Wikipedia, 'The Free Encyclopedia that Anyone Can Edit'.
We use the articles in the categories (to depth three) of Physics and
Philosophy and extract and focus on significant editors (at least 7 or 10 edits
per each article). We construct a bipartite network, and from it, overlapping
cliques of densely connected articles and editors. We cluster these densely
connected cliques into larger modules to study examples of larger groups that
display how volunteer editors flock around articles driven by interest,
real-world controversies, or the result of coordination in WikiProjects. Our
results confirm that topics aggregate editors; and show that highly coordinated
efforts result in dense clusters. Keywords: Wikipedia, bicliques, collaboration, meso-level | |||
| SAVVY Wiki: a context-oriented collaborative knowledge management system | | BIBAK | Full-Text | PDF | 6 | |
| Takafumi Nakanishi; Koji Zettsu; Yutaka Kidawara; Yasushi Kiyoki | |||
| This paper presents a new Wiki called SAVVY Wiki that realizes
context-oriented, collective and collaborative knowledge management
environments that are able to reflect users' intentions and recognitions. Users
can collaboratively organize fragmentary knowledge with the help of the SAVVY
Wiki. Fragmentary knowledge, in this case, implies existing Wiki content,
multimedia content on the web, and so on. Users select and allocate fragmentary
knowledge in different contexts onto the SAVVY Wiki. Owing to this operation,
it is ensured that related pages belong to the same contexts. That is, users
can find correlations among the pages in a Wiki. The SAVVY Wiki provides new
collective knowledge created from fragmentary knowledge, depending on contexts,
in accordance with the users' collaborative operations. Various collaborative
working environments have been developed for the sharing of collective
knowledge. Most current Wikis have a collaborative editing mode to every page,
as a platform to enable a collaborative working environment. In order to
understand an arbitrary concept thoroughly, it is necessary to find
correlations among the various threads of content, depending on the users'
purpose, task or interest. In a Wiki system, it is important to realize a
collaborative editing environment with correlation among pages depending on the
contexts. In this paper, we present a method to realize the SAVVY Wiki, and
describe its developing prototype system. Keywords: Wikis, collaborative working environment, collective knowledge,

| Herding the cats: the influence of groups in coordinating peer production | | BIBAK | Full-Text | PDF | 7 | |
| Aniket Kittur; Bryan Pendleton; Robert E. Kraut | |||
| Peer production systems rely on users to self-select appropriate tasks and
"scratch their personal itch". However, many such systems require significant
maintenance work, which also implies the need for collective action, that is,
individuals following goals set by the group and performing good citizenship
behaviors. How can this paradox be resolved? Here we examine one potential
answer: the influence of social identification with the larger group on
contributors' behavior. We examine Wikipedia, a highly successful peer
production system, and find a significant and growing influence of group
structure, with a prevalent example being the WikiProject. Comparison of
editors who join projects with those who do not and comparisons of the joiners'
behavior before and after they join a project suggest their identification with
the group plays an important role in directing them towards group goals and
good citizenship behaviors. Upon joining, Wikipedians are more likely to work
on project-related content, to shift their contributions towards coordination
rather than production work, and to perform maintenance work such as reverting
vandalism. These results suggest that group influence can play an important
role in maintaining the health of online communities, even when such
communities are putatively self-directed peer production systems. Keywords: Wikipedia, coordination, groups, organizational citizenship behavior, peer
production, self-identification | |||
| The singularity is not near: slowing growth of Wikipedia | | BIBAK | Full-Text | PDF | 8 | |
| Bongwon Suh; Gregorio Convertino; Ed H. Chi; Peter Pirolli | |||
| Prior research on Wikipedia has characterized the growth in content and
editors as being fundamentally exponential in nature, extrapolating current
trends into the future. We show that recent editing activity suggests that
Wikipedia growth has slowed, and perhaps plateaued, indicating that it may have
come against its limits to growth. We measure growth, population shifts, and
patterns of editor and administrator activities, contrasting these against past
results where possible. Both the rate of page growth and editor growth has
declined. As growth has declined, there are indicators of increased
coordination and overhead costs, exclusion of newcomers, and resistance to new
edits. We discuss some possible explanations for these new developments in
Wikipedia including decreased opportunities for sharing existing knowledge and
increased bureaucratic stress on the socio-technical system itself. Keywords: Wikipedia, growth, logistic model, population, power law, resistance | |||
| Lively Wiki a development environment for creating and sharing active web content | | BIBAK | Full-Text | PDF | 9 | |
| Robert Krahn; Dan Ingalls; Robert Hirschfeld; Jens Lincke; Krzysztof Palacz | |||
| Wikis are Web-based collaborative systems designed to help people share
information. Wikis have become popular due to their openness which gives users
complete control over the organization and the content of wiki pages.
Unfortunately existing wiki engines restrict users to enter only passive
content, such as text, graphics, and videos and do not allow users to customize
wiki pages. Thus, wikis cannot be used to host or author rich dynamic and
interactive content. In this paper we present Lively Wiki, a development and
collaboration environment based on the Lively Kernel which enables users to
create rich and interactive Web pages and applications -- without leaving the
Web. Lively Wiki combines the wiki metaphor with a direct-manipulation user
interface and adds a concept for Web programming as well as programming tool
support to create an easy to use, scalable, and extendable Web authoring tool.
Moreover, Lively Wiki is self-supporting, i.e. the development tools were used
for creating its own implementation thereby giving users the freedom to
customize every aspect of the system. Keywords: Wiki, content organization, natural language processing, user interaction; Wikis, application Wikis, development environment, end-user programming,

| Adessowiki on-line collaborative scientific programming platform | | BIBAK | Full-Text | PDF | 10 | |
| Roberto A. Lotufo; Rubens C. Machado; André Körbes; Rafael G. Ramos | |||
| Adessowiki (http://www.adessowiki.org) is a collaborative environment for
development, documentation, teaching and knowledge repository of scientific
computing algorithms. The system is composed of a collection of collaborative
web pages in the form of a wiki. The articles of this wiki can embed
programming code that will be executed on the server when the page is rendered,
incorporating the results as figures, texts and tables on the document. The
execution of code at the server allows hardware and software centralization and
access through a web browser. This combination of a collaborative wiki
environment, central server and execution of code at rendering time enables a
host of possible applications like, for example: a teaching environment, where
students submit their reports and exercises on Adessowiki without needing to
install special software; authoring of texts, papers and scientific computing
books, where figures are generated in a reproducible way by programs written by
the authors; comparison of solutions and benchmarking of algorithms given that
all the programs are executed under the same configuration; creation of an
encyclopedia of algorithms and executable source code. Adessowiki is an
environment that carries simultaneously documentation, programming code and
results of its execution without any software configuration such as compilers,
libraries and special tools at the client side. Keywords: Wikis, knowledge sharing, social search; Wiki, collaborative programming, software engineering | |||
| Measuring the wikisphere | | BIBAK | Full-Text | PDF | 11 | |
| Jeff Stuckman; James Purtilo | |||
| Due to the inherent difficulty in obtaining experimental data from wikis,
past quantitative wiki research has largely been focused on Wikipedia, limiting
the degree that it can be generalized. We developed WikiCrawler, a tool that
automatically downloads and analyzes wikis, and studied 151 popular wikis
running Mediawiki (none of them Wikipedias). We found that our studied wikis
displayed signs of collaborative authorship, validating them as objects of
study. We also discovered that, as in Wikipedia, the relative contribution
levels of users in the studied wikis were highly unequal, with a small number
of users contributing a disproportionate amount of work. In addition, power-law
distributions were successfully fitted to the contribution levels of most of
the studied wikis, and the parameters of the fitted distributions largely
predicted the high inequality that was found. Along with demonstrating our
methodology of analyzing wikis from diverse sources, the discovered
similarities between wikis suggest that most wikis accumulate edits through a
similar underlying mechanism, which could motivate a model of user activity
that is applicable to wikis in general. Keywords: Wiki, Wikipedia, bug fixing, commons based peer production, coordination,

| An architecture to support intelligent user interfaces for Wikis by means of Natural Language Processing | | BIBAK | Full-Text | PDF | 12 | |
| Johannes Hoffart; Torsten Zesch; Iryna Gurevych | |||
| We present an architecture for integrating a set of Natural Language
Processing (NLP) techniques with a wiki platform. This entails support for
adding, organizing, and finding content in the wiki. We perform a comprehensive
analysis of how NLP techniques can support the user interaction with the wiki,
using an intelligent interface to provide suggestions. The architecture is
designed to be deployed with any existing wiki platform, especially those used
in corporate environments. We implemented a prototype integrating the NLP
techniques keyphrase extraction and text segmentation, as well as an improved
search engine. The prototype is integrated with two widely used wiki platforms:
Media-Wiki and TWiki. Keywords: Wiki, content organization, natural language processing, user interaction | |||
| Social search and need-driven knowledge sharing in Wikis with Woogle | | BIBAK | Full-Text | PDF | 13 | |
| Hans-Jörg Happel | |||
| Wikis have emerged as easy and flexible tools for accessing and sharing
knowledge on the internet and within organizations. Due to their highly
collaborative nature, users can typically modify and create content without any
access restrictions since these are replaced by social practices. On the other
hand, due to the lack of central guidance, knowledge sharing is driven by the
individual choice of contributors. We claim that -- especially in enterprise
settings -- the lack of guidance for content creation is a major problem. We
therefore analyze search and knowledge sharing in current Wikis. To improve
knowledge sharing, we present the Woogle concept, which introduces "Social
Search" and "Need-driven Knowledge Sharing" into Wikis. We describe our
prototype implementation Woogle4MediaWiki and results from initial evaluation
studies. Keywords: Wikis, knowledge sharing, social search | |||
| Wikibugs: using template messages in open content collections | | BIBAK | Full-Text | PDF | 14 | |
| Loris Gaio; Matthijs den Besten; Alessandro Rossi; Jean-Michel Dalle | |||
| In the paper we investigate an organizational practice meant to increase the
quality of commons-based peer production: the use of template messages in
wiki-collections to highlight editorial bugs and call for intervention. In the
context of SimpleWiki, an online encyclopedia of the Wikipedia family, we focus
on {complex}, a template which is used to flag articles disregarding the
overall goals of simplicity and readability. We characterize how this template
is placed on and removed from articles and we use survival analysis to study
the emergence and successful treatment of these bugs in the collection. Keywords: Wiki, Wikipedia, bug fixing, commons based peer production, coordination,

| A jury of your peers: quality, experience and ownership in Wikipedia | | BIBAK | Full-Text | PDF | 15 | |
| Aaron Halfaker; Aniket Kittur; Robert Kraut; John Riedl | |||
| Wikipedia is a highly successful example of what mass collaboration in an
informal peer review system can accomplish. In this paper, we examine the role
that the quality of the contributions, the experience of the contributors and
the ownership of the content play in the decisions over which contributions
become part of Wikipedia and which ones are rejected by the community. We
introduce and justify a versatile metric for automatically measuring the
quality of a contribution. We find little evidence that experience helps
contributors avoid rejection. In fact, as they gain experience, contributors
are even more likely to have their work rejected. We also find strong evidence
of ownership behaviors in practice despite the fact that ownership of content
is discouraged within Wikipedia. Keywords: WikiWork, Wikipedia, experience, ownership, peer, peer review, quality | |||
| Assessing the quality of Wikipedia articles with lifecycle based metrics | | BIBAK | Full-Text | PDF | 16 | |
| Thomas Wöhner; Ralf Peters | |||
| The main feature of the free online-encyclopedia Wikipedia is the wiki-tool,
which allows viewers to edit the articles directly in the web browser. As a
weakness of this openness for example the possibility of manipulation and
vandalism cannot be ruled out, so that the quality of any given Wikipedia
article is not guaranteed. Hence the automatic quality assessment has been
becoming a high active research field. In this paper we offer new metrics for
an efficient quality measurement. The metrics are based on the lifecycles of
low and high quality articles, which refer to the changes of the persistent and
transient contributions throughout the entire life span. Keywords: Wikipedia, Wikipedia lifecycle, persistent contribution, quality assessment,
transient contribution | |||
| Wiki credibility enhancement | | BIBAK | Full-Text | PDF | 17 | |
| Felix Halim; Wu Yongzheng; Roland Yap | |||
| Wikipedia has been very successful as an open encyclopedia which is editable
by anybody. However, the anonymous nature of Wikipedia means that readers may
have less trust since there is no way of verifying the credibility of the
authors or contributors. We propose to automatically transfer external
information about the authors from outside Wikipedia to Wikipedia pages. This
additional information is meant to enhance the credibility of the content. For
example, it could be the education level, professional expertise or affiliation
of the author. We do this while maintaining anonymity. In this paper, we
present the design and architecture of such system together with a prototype. Keywords: OpenID, Wikipedia, anonymity, credibility, login | |||
| Organizing the vision for web 2.0: a study of the evolution of the concept in Wikipedia | | BIBAK | Full-Text | PDF | 18 | |
| Arnaud Gorgeon; E. Burton Swanson | |||
| Information Systems (IS) innovations are often characterized by buzzwords,
reflecting organizing visions that structure and express the images and ideas
formed by a wide community of users about their meaning and purpose. In this
paper, we examine the evolution of Web 2.0, a buzzword that is now part of the
discourse of a broad community, and look at its entry in Wikipedia over the
three years since its inception in March 2005. We imported the revision history
from Wikipedia, and analyzed and categorized the edits that were performed and
the users that contributed to the article. The patterns of evolution of the
types and numbers of contributors and edits lead us to propose four major
periods in the evolution of the Web 2.0 article: Seeding, Germination, Growth
and Maturity. During the Seeding period, the article evolved mostly
underground, with few edits and few contributors active. The article growth
took off during the Germination period, receiving increasing attention. Growth
was the most active period of development, but also the most controversial.
During the last period, Maturity, the article received a decreasing level of
attention, current and potential contributors losing interest, as a consensus
about what the concept of Web 2.0 means seemed to have been reached. Keywords: Wikipedia, organization vision, phases, revision history, web 2.0 | |||

| Cosmos: a Wiki data management system | | BIBAK | Full-Text | PDF | 22 | |
| Qinyi Wu; Calton Pu; Danesh Irani | |||
| Wiki applications are becoming increasingly important for knowledge sharing
between large numbers of users. To prevent against vandalism and recover from
damaging edits, wiki applications need to maintain revision histories of all
documents. Due to the large amounts of data and traffic, a Wiki application
needs to store the data economically on disk and processes them efficiently.
Current wiki data management systems make a trade-off between storage
requirement and access time for document update and retrieval. We introduce a
new data management system, Cosmos, to balance this trade-off. Keywords: Wikis, version control systems | |||

| Wikis to support collaborative web spaces to promote youth well-being | | BIBA | Full-Text | PDF | 24 | |
| Shahper Vodanovich; Max Rohde; Ching-shen Dong; David Sundaram | |||
| Youth is a period of rapid emotional, physical and intellectual change, where young people progress from being dependent children to independent adults. Young people who are unable to make this transition smoothly can face significant difficulties in both the short and long term. Although the vast majority of young people are able to find all the resources they need for their health, well-being and development within their families and living environments, some young people have difficulty in locating resources that can help them and, moreover, difficulty in integrating into society. One way to support this transition is to create an environment that enables youth to be well supported through the provision of information and the creation of a community where youth feel empowered to collaborate with their peers as well as decision makers and legislators. | |||

| John Rankin; Craig Anslow; James Noble; Brenda Chawner; Donald Gordon | |||
| Web and print exist as two solitudes: printed web pages often disappoint and
converting print documents into good web pages is hard. A wiki makes it easy
for authors to create rich web content, but is little help if readers wish to
print the results. Wikipublisher lets readers turn wiki pages or page
collections into print, with a quality better than most word processing
documents. This lowers the time and cost of creating online and print versions
of the same content, with no loss of quality in either medium. Keywords: Wiki markup, Wikis, printing the web, web publishing | |||

| Leveraging crowdsourcing heuristics to improve search in Wikipedia | | BIBA | Full-Text | PDF | 27 | |
| Yasser Ganjisaffar; Sara Javanmardi; Cristina Lopes | |||
| Wikipedia articles are usually accompanied with history pages, categories and talk pages. The meta-data available in these pages can be analyzed to gain a better understanding of the content and quality of the articles. We analyze the quality of search results of the current major Web search engines (Google, Yahoo! and Live) in Wikipedia. We discuss how the rich meta-data available in wiki pages can be used to provide better search results in Wikipedia. We investigate the effect of incorporating the extent of review of an article into ranking of search results. The extent of review is measured by the number of distinct editors who have contributed to the articles and is extracted by processing Wikipedia's history pages. Our experimental results show that re-ranking search results of the three major Web search engines, using the review feature, improves quality of their rankings for Wikipedia-specific searches. | |||
| Evaluating the trustworthiness of Wikipedia articles through quality and credibility | | BIBAK | Full-Text | PDF | 28 | |
| Sai T. Moturu; Huan Liu | |||
| Wikipedia has become a very popular destination for Web surfers seeking
knowledge about a wide variety of subjects. While it contains many helpful
articles with accurate information, it also consists of unreliable articles
with inaccurate or incomplete information. A casual observer might not be able
to differentiate between the good and the bad. In this work, we identify the
necessity and challenges for trust assessment in Wikipedia, and propose a
framework that can help address these challenges by identifying relevant
features and providing empirical means to meet the requirements for such an
evaluation. We select relevant variables and perform experiments to evaluate
our approach. The results demonstrate promising performance that is better than
comparable approaches and could possibly be replicated with other social media
applications. Keywords: Wikipedia, quality, social media, trust, trustworthiness | |||

| Software development is a knowledge-intensive activity and frequently
implies a progressive crystallization of knowledge, towards programming
language statements. Although wikis have proved very effective, for both
collaborative authoring and knowledge management, it would be useful for
knowledge acquisition to better support team awareness and the recognition of
knowledge structures, their relations, and their incremental evolution. This

| Wikis4SE 2009: wikis for software engineering | | BIBAK | Full-Text | PDF | 39 | |
| Ademar Aguiar; Nuno Flores; Paulo Merson | |||
| Due to the simplicity, attractiveness and effectiveness for collaborative
authoring and knowledge management, wikis are now massively disseminated and
used in different domains. This workshop focuses on wikis for the specific
domain of software engineering. It aims at bringing together researchers,
practitioners, and enthusiasts interested on researching, exploring and
learning how wikis can be improved, customized and used to better support
software engineering. Based on lessons learned and obstacles identified, a
research agenda will be defined with key opportunities and challenges. This
edition at WikiSym'2009 follows others at ICSE'2009, WikiSym'2008 and
WikiSym'2007. Keywords: Wikis, Wikis for software engineering, collaboration, documentation,

| Measuring Wikipedia: a hands-on tutorial | | BIBAK | Full-Text | PDF | 40 | |
| Luca de Alfaro; Felipe Ortega | |||
| This tutorial is an introduction to the best methodologies, tools and
practices for Wikipedia research. The tutorial will be led by Luca de Alfaro
(Wiki Lab at UCSC, California, USA) and Felipe Ortega (Libresoft, URJC, Madrid,
Spain). Both cumulate several years of practical experience exploring and
processing Wikipedia data [1], [2], [3]. As well, their respective research
groups have led the development of two cutting-edge software tools (WikiTrust
and WikiXRay), for analyzing Wikipedia. WikiTrust implements an author
reputation system, and a text trust system, for wikis. WikiXRay is a tool
automating the quantitative analysis of any language version of Wikipedia (in
general, any wiki based on MediaWiki). Keywords: WikiTrust, WikiXRay, Wikipedia, data mining, empirical research,

| Tutorial on agile documentation with Wikis | | BIBAK | Full-Text | PDF | 41 | |
| Ademar Aguiar | |||
| Although some agile projects can succeed without producing any documentation
at all, others may require a little more. Best practices of agile documentation
suggest producing just enough documentation, at just the right time, and for
just the right audience. It is not by coincidence that wikis and agility share
goals of simplicity, flexibility, and open collaboration, thus being natural
documentation tools to agile projects. When well integrated with other tools,
wikis provide open collaboration, quick feedback, easy navigability, integrated
contents, and a low barrier for developers to document. In this hands-on
tutorial, participants will learn how to adapt and use a wiki to better support
software projects. Keywords: Wikis, Wikis for software engineering, collaboration, documentation,

| 3DWiki: the 3D Wiki engine | | BIBAK | Full-Text | PDF | 42 | |
| Jacek Jankowski; Marek Jozwowicz; Yolanda Cobos; Bill McDaniel; Stefan Decker | |||
| We demonstrate one of the potential paths of the evolution of wiki engines
towards Web 3.0. We introduce 3dWiki -- the 3D wiki engine, which was built
according to 2-Layer Interface Paradigm (2LIP). It was developed for use by
Copernicus, our vision of a 3D encyclopedia. In the demonstration:
* We give an overview of 2-Layer Interface Paradigm, an attempt to marry
advantages of 3D experience with the advantages of narrative structure of hypertext. * We describe step by step how to create an article for Copernicus: from creating models for the 3D background, through authoring the content, creating the c-links, to publishing the result in our encyclopedia. * We show how to use a physics engine in our wiki.
