Racer: An OWL Reasoning Agent for the Semantic Web
Volker Haarslev, Ralf Möller · 2003
Racer, which can be considered as a core reasoning agent for the semantic web, is briefly described. Racer currently sup-ports a wide range of inference services about ontologies spec-ified in the Ontology Web Language (OWL). These services are made available to other agents via network based APIs. Racer is currently used by various clients such as ontology editors, ontology development and visualization tools, and a first web-based prototype for exploration and analysis of OWL ontolo-gies. 1
