document: Foundations for service ontologies : aligning OWL-S to dolce Clarity in semantics and a rich formalization of this semantics are important requirements for ontologies designed to be deployed in large-scale , open , distributed systems such as the envisioned Semantic Web This is especially important for the description of Web Services , which should enable complex tasks involving multiple agents . As one of the first initiatives of the Semantic Webcommunity for describing Web Services , OWL-S attracts a lot of interest even though it is still under development . We identify problematic aspects of OWL-S and suggest enhancements through alignment to a foundational ontology . Another contribution of ourwork is the Core Ontology of Services that tries to fill the epistemological gap between the foundational ontology and OWL-S . It can be reused to align other Web Service description languages as well . Finally , we demonstrate the applicability of our work byaligning OWL-S ' standard example called CongoBuy .
