Abstract

In this paper we proposed a new semantics for the combination of production systems with arbitraryDL ontologies. Unlike previous approaches, the semantics presented here allow looping rules and can handle inconsistencies produced by the interaction of the rule actions and the ontology. We also define a sound embedding of such semantics, restricted to rule-based DL Ontologies, into Transaction Logic with partial action definitions (ΤRPAD). This reduction adds a declarative semantics to the combination. To model production systems in ΤRPAD, we extend ΤRPAD with default negation and define the well-founded semantics for it.
