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.

Relevance of the Topic

Semantic wikis are a major way of making communities of humans and automated agents collaborate in producing knowledge usable by both parties. The Semantic Wiki research community have already delivered systems that are widely used. Semanticweb.org, a wiki-driven site itself, lists around 12 actively maintained semantic wiki engines , powering hundreds of web sites. The systems have matured and the application areas have diversified. Practitioners and end-users are now adopting semantic wikis in practical settings, such as enterprise knowledge management, or driving large social web sites. The usage of these systems produce feedback that is under analysis by the semantic wiki research community. It unveils a number of research questions, which the academic community has to answer now in a consolidated effort.
This workshop will be the fourth formal meeting of researchers interested in semantic wikis. The aim is to exchange ideas, to discuss pressing research questions arising from practical usage of semantic wikis, and to explore integrations of wikis with other semantic web technologies. The outcome of the workshop will be :
  • Collection of open research questions
  • Structuring the research area (open space session, documented in the Semanticweb.org wiki)
  • Experience reports – what works in semantic wikis and what does not (yet)?
  • State-of-the art overview of applications of semantic wikis
As semantic wikis are like "petri dishes" for the whole Semantic Web, these outcomes will be of relevance not only to the semantic wiki community but to the Semantic Web community as a whole.

Workshop Audience

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.

The core of the semantic wiki community, mostly represented in the Semantic Wiki Interest Group , currently consists of around 250 researchers. Contributions to the 2008 workshop on semantic wikis show that there are other research communities that apply semantic wikis or contribute to semantic wiki research, even though they may use different terminologies, such as “knowledge wikis” or “wikis for formalized …” (e.g. math). Also, the recent emergence of a Ontolog mini-series on the topic of semantic wikis demonstrates increasing interest even outside the core community. We aim at establishing connections between these communities.

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)

Proceedings

The Semantic Wiki Workshop traditionally follows an Open Access strategy to make scientific results available for free. The proceedings are therefore available as CEUR online proceedings, Volume 464 at ceur-ws.org/Vol-464/ . Both full proceedings and individual papers are available for download.

Related Events

Previous semantic wiki workshops took place at ESWC 2006 (largest workshop with ~100 people, ~40 submissions), WikiSym 2006, and ESWC 2008 (2nd largest workshop, 21 submissions); see semwiki.org/ . Other related events were a US-based workshop “ WikiAI 08 – Wikipedia and Artificial Intelligence: An Evolving Synergy” at AAAI, and the WikiSym conference series (on wikis in general, only one submission on semantic wikis). The interest of the community in the topic is exemplified by the large audience in the ontolog teleconference mini series on semantic wikis , consisting of six sessions.

Support

The workshop is supported by the EU FP7 project KIWI - Knowledge in a Wiki, which will also offer financial support, e.g. by sponsoring a best paper award or the planned dinner.

Organizing Committee

All organizers were also organizers of the semantic wiki workshop at ESWC 2008.

Christoph Lange is a Ph.D. student at Jacobs University Bremen, Germany. His research focuses on collaborative authoring of semiformal mathematical knowledge – which he tries to enable by using semantic web technologies. He is developing SWiM , a semantic wiki for mathematics, supporting scientists and learners. He was a PC member and/or reviewer for several workshops and conferences in the semantic web area, e.g. I-SEMANTICS 2007 and 2008, and has edited a book about using, administering, and customizing wikis.

Dr. Sebastian Schaffert is working as a Senior Researcher and Project Manager at the group for Knowledge-based Information Systems (KIS) at Salzburg Research. He is also Scientific Director of Salzburg NewMediaLab (SNML), the Austrian industry competence centre on New Media hosted by Salzburg Research and co-ordinator of the EU FP7 project KIWI (Knowledge in a Wiki), which started in March 2008. KIWI's main topic is knowledge management with Semantic Wikis. Sebastian received his PhD from the University of Munich in 2004 in the area of reasoning. Among other topics, Sebastian Schaffert is primarily engaged in research on the Social Semantic Web and Knowledge Management, where he is a well-known representative. Sebastian Schaffert was co-programme chair of previous Semantic Wiki workshops (2006 in Budva, 2008 in Tenerife) and of the Semantics conference series (2006 in Vienna, 2007 and 2008 in Graz).

Dr. Hala Skaf-Molli received her Ph.D. in Computer Science from Nancy University in 1997. Since 1998, she is Associate Professor at University of Nancy. She is member of the INRIA ECOO (Environments for Cooperation) project. Dr. Skaf-Molli has mainly worked on collaborative environments and focused on problems of semantic consistency of shared data in collaborative environments and awareness models for collaborative editing. She has been or is regular Program Committee member of the conferences ICEIS since 2003, IFIP CONFENIS 2007, ICTTA 2008 and IADIS Information System 2009. She was a member of the local organization committee of Wise2007 conference and co-chair of the special session on Computer Supported Collaborative Editing in iceis2007.
