                      IJCAI 2009 Workshop
                   Pasadena, CA - July 13, 2009

                     CALL FOR PARTICIPATION


The performance of an Artificial Intelligence system often depends 
on the amount of world knowledge available to it. During the last 
decade, the AI community has witnessed the emergence of a number 
of highly structured knowledge repositories whose collaborative 
nature has led to a dramatic increase in the amount of world 
knowledge that can now be exploited in AI applications. Arguably, 
the best-known repository of user-contributed knowledge is 
Wikipedia. Since its inception less than eight years ago, it has 
become one of the largest and fastest growing online sources of
encyclopedic knowledge. One of the reasons why Wikipedia is appealing
to contributors and users alike is the richness of its embedded
structural information: articles are hyperlinked to each other and
connected to categories from an ever expanding taxonomy; pervasive
language phenomena such as synonymy and polysemy are addressed 
through redirection and disambiguation pages; entities of the same type 
are described in a consistent format using infoboxes; related articles are
grouped together in series templates.

Many more repositories of user-contributed knowledge exist besides
Wikipedia. Collaborative tagging in Delicious and community-driven
question answering in Yahoo! Answers and Wiki Answers are only a few
examples of knowledge sources that, like Wikipedia, can become a
valuable asset for AI researchers. Furthermore, AI methods have 
the potential to improve these resources, as demonstrated recently 
by research on personalized tag recommendations, or on matching user 
questions with previously answered questions.

The goal of the workshop is to foster the research and dissemination 
of ideas on the mutually beneficial interaction between AI and
repositories of user-contributed knowledge. We encourage the
participation of researchers from different perspectives, including
(but not limited to) machine learning, computational linguistics,
information retrieval, information extraction, question answering,
knowledge representation, and others. We also encourage participation
of researchers from other areas who might benefit from the use of
large bodies of machine-readable knowledge.


Topics covered by this workshop include, but are not limited to:
- Using user-contributed knowledge as a source of training data for AI 
- Automatic methods for improving the quality of user contributions
- Routing tasks to people who have the expertise to perform them well
- Integrating Wikipedia with existing ontologies (e.g. WordNet, CYC, ODP)
- Extracting annotated data from user contributions
- Enriching user contributions with new types of structural information
- User-contributed knowledge and the Semantic Web / Web 2.0
- Automatic extraction and use of cross-lingual information
