Ian Horrocks is a Professor of Computer Science at the University of Oxford in the UK. His research focuses on knowledge representation, particularly ontology languages, description logics, and optimised reasoning algorithms.

His work on tableau reasoning for very expressive description logics has formed the basis of most description logic reasoning systems in use today, including Racer, FaCT++ and Pellet.

Prof. Horrocks was jointly responsible for development of the OIL and DAML+OIL ontology languages, and he played a central role in the development of the Web Ontology Language OWL.
