Description Logic Programs: Combining Logic Programs with Description Logic
Grosof, Benjamin - Horrocks, Ian - Volz, Raphael - Decker, Stefan

Formato:	Working Paper
Enlaces:	We show how to interoperate, semantically and inferentially, between the leading Semantic Web approaches to rules (RuleML Logic Programs) and ontologies (OWL/DAML+OIL Description Logic) via analyzing their expressive intersection. To do so, we define a new intermediate knowledge representation (KR)…
