%X 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.

%X 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".

%X 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.

%X 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.

%X 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.

%X 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.

%X 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.

%X 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.

%X 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.

%X 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.

%X 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.

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.

%X 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.

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.

%X 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.

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.

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

%X 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.

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.

%X 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.

%X 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.

%X DynaTable is an extension for the MediaWiki software that provides support
for structured data. While tables and lists are popular features in many wikis,
they are currently unsupported as first-class entities. As a consequence,
creating and editing tables is a manual, error-prone task. DynaTable allows
wiki editors to create tables that can be displayed on and transcluded to
multiple wiki pages, and can be partially displayed based on different
criteria.

%X 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.

%X 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.

pilot locations. Also presented are students' self-reported recommendations for
possible improvements to the wiki. Results indicate that some locations were
more active in their wiki use; the poster addresses location-specific
implementation context factors that may have played a role in the variant

%X 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
paper presents Weaki, a wiki prototype especially designed to support
incremental formalization of structured contents that uses weakly-typed pages
and type evolution. Weaki was applied in academic settings, by students of
Software Engineering Labs.

things as: collaborate across locations; brainstorm and track projects;
organize knowledge; and facilitate information sharing. This poster reports
preliminary findings from the analysis of the logs of two wikis, which
supported two different software development projects. This work shows that,
with the wiki log analysis, it is possible to identify patterns of information
sharing.

%X 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.

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.
