Workshop Description:

The Semantic Web is a major world-wide endeavour to advance the Web by enriching its content with semantic meta-information that can be processed by inference-enabled Web applications. Ontologies and automated reasoning are key techniques in the semantic web initiative.

Rules are considered to be a major issue in the further development of the semantic web. On one hand, they can be used in ontology languages, either in conjunction with or as an alternative to description logics. And on the other hand, they will act as a means to draw inferences, to express constraints, to specify policies, to react to events/changes, to transform data, etc.

Finally, rule markup languages will allow to enrich web ontologies by adding definitions of derived concepts, to publish rules on the Web, to exchange rules between different systems and tools, etc.

The workshop builds on the success of the first workshop RuleML2002 ( held in conjunction with ISWC2002 on Sardinia, Italy, and the second workshop ( held in conjunction with ISWC2003 on Sanibel Island, USA. This year's workshop combines that tradition, in the sense of being the premier RuleML-2004 event, with casting as wide a net as possible regarding all kinds of Rules and Rule Markup Languages for the Semantic Web.

Topics of Interest:

We encourage submissions on all topics related to rules and rule mark-up lanugages for the Semantic Web. In particular, the workshop seeks papers addressing syntax and semantics of rule languages, execution engines, implemented systems, and applications. Specifically:


We invite articles of no more than 15 pages length formated in Springer's LNCS style ( describing original completed work, work in progress, or interesting problems or use cases. Submitted papers will be fully refereed based on the originality and significance of the ideas presented as well as on technical aspects.

Proceedings will be published by Springer in the LNCS series, volume number 3323 ( A special issue, RULES FOR THE SEMANTIC WEB, of the Journal of Web Semantics is also planned, providing an opportunity to resubmit selected revised, extended papers.

Submissions should be made electronically, in postscript or, preferably, PDF to both
antoniou at AND harold.boley at BEFORE OR BY 12 July 2004.
