We consider a realization of Reiter-style default logic on top of description logic knowledge bases (DL-KBs). To this end, we present elegant transformations from default theories to conjunctive query (cq-)programs that combine rules and ontologies, based on different methods to find extensions of default theories. The transformations, which are implemented in a front-end to a DL-reasoner, exploit additional constraints to prune the search space via relations between default conclusions and justifications. The front-end is a flexible tool for customizing the realization, allowing to develop alternative or refined default semantics. To our knowledge, no comparable implementation is available. |
