Fourth Workshop on Semantic Wikis
The Semantic Wiki Web [SemWiki2009]
co-located with ESWC 2009, Heraklion, Crete

Supported by the EU Project KiWi - Knowledge in a Wiki
(http://www.kiwi-project.eu)


Goals and Motivation
====================

Wikis are a major success of Web 2.0. They are used for a large number of
purposes, such as encyclopedias, project documentation, and
coordination, both in open communities and in enterprises. Wikis have
demonstrated how it is possible to transform a community of strangers into
a community of collaborators. By integrating Semantic Web technologies,
semantic wikis one the one hand allow this new community of contributors
to produce formalized knowledge readable by machines and on the other hand
support the users in ways ordinary wikis are not capable of, e.g. by
personalisation, integration with other services, and reasoning. Authoring
and usage of informal and formal data take place in the same system,
leading to instant gratification. Some systems simply tag existing wiki
content, others are full-fledged ontology editors, but the majority
covers the large scale between informal and fully formalized content,
guiding users from informal knowledge contained in texts to more formal
structures.

Semantic wikis are a very promising way to establish a partnership between
human and automated collaborators, creating communities for collaborative
knowledge building and sharing. Some important steps have already been
achieved with systems that are already adopted outside of the original
Semantic Web community. Semantic wikis are thus even now a major success
story of the Semantic Web and a reference that combines the advantage of
Web 2.0 and the Web of data and have the potential to significantly
contribute to the adoption of semantic technologies throughout the Web.

The goal of this workshop is to study how interactions within a semantic
wiki between humans and between humans and machines can help both parties
to collaboratively produce and share knowledge that is usable for human and
computers. As semantic wikis contain many of the core Semantic Web
challenges in an integrated fashion, we are also concerned about contributing
results obtained in semantic wiki "petri dishes" to the overall Semantic Web
effort.


Workshop Audience and Topics
============================

We want to bring together researchers and practitioners active in the
development and application of traditional and semantic wiki systems, as
well as researchers interested in knowledge acquisition in general and in
computer supported cooperative work. This includes researchers working on
semantic portals, personal and enterprise knowledge management systems
and ontology authoring. We address researchers working on (but not limited
to):

* Applications of semantic wikis in
- e-science and e-learning
- software and knowledge engineering
- enterprise workflows and knowledge management
- personal knowledge management
- ... and other fields
* Integration and reuse of semantic wikis or (semantic) wiki content:
- integrations with other semantic applications; mashups
- wikis and Linked Open Data; scaling wikis to the web
- giving semantics to non-semantic wikis (e.g. Wikipedia)
- reusing semantics gained from wikis (e.g. DBpedia)
* Human and social factors of semantic wikis
- usability studies, empirical studies, analyses of semantic wiki
contributors and their contributions
- overcoming entrance barriers, giving incentives for contributing
- connecting knowledge and social interaction
- community building
* Knowledge representation and reasoning in semantic wikis
- combining formal and informal knowledge, transforming informal to
formal knowledge, making formal knowledge accessible
- coping with inconsistencies
- change management, truth maintenance, versioning, and undoing semantic
changes
- utilizing emerging knowledge models
- semantic wikis for rapid prototyping of schema-driven applications
- collaborative ontology engineering with wikis
* Technologies for semantic wikis
- privacy: permissions, trust, licensing, access control
- browsing, navigating, visualizing semantically enhanced linked data
- distributed semantic wikis: offline/distributed/real-time/multi-
synchronous editing
- innovative plugins and extensions for existing systems
(e.g. Semantic MediaWiki)

Submission and Proceedings
==========================

We invite the following different kinds of contributions:
* full research or application papers (15 pages) describing recent research
outcomes, mature work, prototypes, applications, or methodologies;
authors of accepted full papers will be able to present their work in a 20
minute talk at the workshop
* short position papers (5-10 pages) describing early work and new ideas
that are not yet fully worked out; authors of short papers will be able to
present their work in a 5-10 minute lightning talk at the workshop
* demo outlines (5 pages) describing the demonstration of a software
prototype in the poster and demo session during the workshop
* poster descriptions (2 pages) outlining a poster to be presented in the
poster and demo session during the workshop

Independently of the type of submission, all papers should be formatted
according to the Springer Lecture Notes in Computer Science (LNCS) format.
For complete details on this issue see Springer's Author Instructions at
http://www.springer.com/computer/lncs?SGWID=0-164-2-72376-0. Papers will be
submitted using the EasyChair system. Access to EasyChair will be given in
time on the workshop homepage (http://www.semwiki.org).

In addition to ordinary submissions, all attendees of the workshop are
encouraged to informally present their work in an open space session during
the workshop if they are not (yet) able to submit a description of their
work or to also discuss more recent work that has been done after the
submission deadline of the workshop.
