AIC Seminar Series

Why We Need Another Rule Language for the Web

Axel PolleresDigital Enterprise Research Institute[Home Page]

Date:  Friday, August 12th 2005 at 11:00am

Location:  EJ228  (Directions)


The Web Rule Language WRL is a rule-based ontology language for the Semantic Web. The language is located in the Semantic Web stack next to the Description Logic based Ontology language OWL. WRL defines three variants, namely Core, Flight and Full. The Core variant marks the common fragment between WRL and OWL. WRL-Flight is a Datalog-based rule language. WRL-Full is a full-fledged rule language with function symbols and negation under the Well-Founded Semantics. In this talk, I will introduce WRL, itÂ’s syntax and semantic underpinnings and relation to other Web languages like OWL, SWRL and RDFS. This is joint work with the WSML Language working group, mainly, Jos De Bruijn, Holger Lausen and Dieter Fensel.
