Description

Databases have always been a very important issue for the World Wide Web, and, conversely, the WWW has stimulated interesting research on databases, for example in the area of semi-structured data. Due to the recent and immense interest in the semantic web initiative, knowledge representation has also gained a considerable amount of attention by the WWW community, and the pollinating impact of this fact on research in knowledge representation is already clearly visible. For these reasons, the focus of KRDB-2003 is on Knowledge Representation and Databases for the World-Wide Web.

For the workshop, we thus solicit contributions that address the interplay between knowledge representation and databases, particularly in contexts related to the World-Wide Web. specific issues we would like to discuss are:

Languages and techniques required to support a semantic web
Construction and maintenance of large ontologies for use in the WWW
Web service modelling and declarative web service retrieval
Context adaption, user models, and adaptive web systems
Query languages for the Web and semi-structured data
Data modelling and typing for XML and semi-structured data

We also solicit submissions that concern the relationship of knowledge representation and databases, but do not fall inside this year's selected topic.
