Abstract: Recently, Information Systems evolved towards distributed architectures relying on P2P technologies, where peers share data and functionalities as services to enable interoperability, without a-priori knowledge about each other. In this context, automatic service discovery is a crucial task. We propose Semantic Driven Service Discovery in a P2P scenario, P2P-SDSD. In our framework, peers that use and supply Web Services are equipped with their own ontologies, to maintain semantic descriptions of local services (local knowledge) and links towards peers, that provide semantically related services (network knowledge). Local and network knowledge constitute a semantic service overlay over the P2P network. Semantic-driven service matchmaking techniques are exploited both to organise services in the semantic overlay and to guide service discovery through the P2P network.
