Foundations for Service Ontologies: Aligning OWL-S to DOLCE http://www2004.org/proceedings/docs/1p563.pdf 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 SemanticWeb. This is especially important for the description ofWeb Services, which should enable complex tasks involving multiple agents. As one of the first initiatives of the Semantic Web community 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 our work 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 by aligning the standard example of OWL-S called CongoBuy.

In this paper we introduce a hybrid system that not only gathers existing FOAF pro files from the Semantic Web, but also applies known web-mining techniques to extract social network information from the original, hypertext web. To motivate our approach, we demonstrate how even the simple information obtained this way can be used effect ively to obtain important insights into a community by applying the methods of Social Network Analysis, a branch of sociology concerned with relational data.
