Ontologies and ontology based systems are becoming increasingly important in meeting the demand for more powerful and flexible information systems. Requirements for such systems include the need to deal with incomplete and semi-structured information, to integrate information from heterogeneous sources, to employ richer and more flexible schemas, and for query answers to reflect both knowledge and data. Provision of such enhanced capabilities must, however, be in addition to, and not instead of, the well-established features of existing database systems, in particular their robust scalability. Achieving this is, of course, extremely challenging. In this talk I will present some recent research efforts that tackle this problem, including investigations of tractable fragments and algorithmic techniques, new optimisations and some remaining research challenges.

Short bio:
Ian Horrocks is a Professor in the Oxford University Computing Laboratory where he jointly (with Georg Gottlob) leads the Information Systems Group. His research interests include description logics, ontology languages, and reasoning systems. He was centrally involved in the development of the OIL, DAML+OIL and OWL ontology languages, and was co-chair of the W3C Working Group that recently developed OWL 2. He also developed algorithms and implementation techniques that are employed in many reasoning systems. He has published more than 150 articles in conferences, journals and books. He is a BCS Fellow, an ECCAI Fellow, an EPSRC Senior Research Fellow and a past winner of the BCS Roger Needham award.
