Pascal Hitzler and Denny Vrandecic. Faster OWL Using Split Programs. In Principles and Practices of Semantic Web Reasoning. Dagstuhl Seminar Proceedings, Volume 5371, pp. 1-2, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2006)


We propose a new technique for approximate ABox reasoning with OWL DL ontologies. Essentially, we obtain substantially improved reasoning performance by disregarding non-Horn features of OWL DL. Our approach comes as a side-product of recent research results concerning a new transformation of OWL DL ontologies into negation-free disjunctive datalog, and rests on the idea of performing standard resolution over disjunctive rules by treating them as if they were non-disjunctive ones. We analyse our reasoning approach by means of non-monotonic reasoning techniques, and present an implementation, called Screech.
