The latest ontology languages can be translated into a description logic (DL), thus providing them with a formal semantics and associated reasoning procedures. We introduce the ordered description logic OSHOQ(D) as a simple decidable extension of SHOQ(D) that supports the direct definition of a preference order on defeasible axioms, thus allowing for a succinct and intuitive expression of defeasible ontologies, containing e.g. exceptions for certain axioms. We demonstrate the usefulness of… CONTINUE READING
