Abstract

We present OWL-log, which is an implementation of the $\mathcal{AL}$-log hybrid knowledge representation system where the Description Logics component is extended to the Web Ontology Language OWL DL. We implemented an OWL-log reasoner coupled to the OWL reasoner Pellet and explored different query-answering strategies. We conducted an experimental study using a modified version of the LUBM benchmark in order to evaluate and compare the efficiency of the strategies. Also, to validate OWL-log’s usefulness we developed a prototype based on the Web ontology browsing and editing tool Swoop.
