   Abstract

State-of-the-art ontology languages are often not sufficiently expressive to accurately represent domains consisting of objects connected in a complex way, for example the complex physically structured objects found in domains such as anatomy, engineering and chemistry. As a possible remedy, we have proposed a powerful yet still decidable extension of ontology languages with "description graphs". In this talk I will motivate the need for such an extension, describe description graphs, explain the restrictions needed in order to retain decidability and outline a reasoning procedure.

   Bio for Ian Horrocks

My research interests include knowledge representation, ontologies and ontology languages, modal and description logics, automated reasoning, implementation and optimisation of reasoning systems, and applications in areas such as e-Science and the Semantic Web.
