Representing knowledge in OWL provides two important limitations; on one hand efficient reasoning on real-world ontologies containing a large set of individuals is still a challenging task. On the other hand though OWL offers a reasonable trade-off between expressibility and decidability, it can not be used efficiently to model certain application domains. In this paper we give an overview of some of the most relevant approaches in this domain and present OWL2Jess, which is a comprehensive converter tool enabling Jess reasoning over OWL ontologies.
