A Semantic Peer-to-Peer Overlay for Web Services Discovery

Abstract

With the growing of semantic web services, distributed and dynamic discovering service becomes a key requirement for service requestors. However, current service discovery mainly focuses on centralized methods, which don't contain enough capability to support dynamic and automatic service discovery. In this paper, we propose a structured peer-to-peer semantic routing system. The peer-to-peer network and semantic matching can be used to support the completely decentralized semantic service discovery. In the presented system, with the semantic service characteristic vector, the semantic service description is distributed on structured P2P network to allow requesters routing and locating services according to semantic similarity and relationship. Finally, experimental result shows that the presented system is efficient and scalable.
