Improving Usability of Description Logics-based Ontologies

Freitag, den 26.1.2007, 14:15 bis 15:45 , Raum B 17

Referent/en: Jeff Pan, University of Aberdeen

Gastgeber: Prof. Dr. Steffen Staab

Kurzbeschreibung:

Description Logics (DLs) are a family of logic based knowledge representation formalisms. Although they have a range of applications, they are perhaps best known as the basis for widely used ontology languages such as OIL, DAML+OIL and OWL, the last of which is now a World Wide Web Consortium (W3C) recommendation (standard). In order to make the DL-based standard ontology language are widely acceptable, ontology usability has been identified one of the key issues in the development of the Semantic Web. In particular, some new reasoning services are required so as to provide more fine-grain support for ontology applications. This talk will report some recent developments of ontology usability (and related reasoning services), such as scalability, ontology explanations, partial ontology reuse and ontology inconsistency/unsatisfiability handling.
