Service-Based Semantic Search in P2P Systems

—Recently, Semantic Web Services have been increasingly adopted to search, access and manipulate information made available from autonomous and heterogeneous systems interacting in a P2P environment. Platform independency is obtained and the possibility of integrating different information sources over the Web is augmented. In P2P networks, characteristic aspects are the highly dynamicity and the absence of a common resource conceptualization. A centralized structure, where providers publish available services and requesters search for them, constitutes a performance bottleneck and a single point of failure; in P2P environments each provider acts as a peer on the network that supplies its own services and it is able to reply to incoming service requests. A semantic infrastructure to organize and support the automatic location of services without a centralized service registry is required. In this paper we present experimental evaluation of a reference architecture to support service-...
