document: A semantic-link-based infrastructure for web service discovery in P2P networks An important issue arising from P2P applications is how to accurately and efficiently retrieve the required Web services from large-scale repositories . This paper resolves this issue by organizing services in the overlay combining the Semantic Service Link Network and the Chord P2P network . A service request will first be routed in the Chord according to the given service operation names and keywords . Then , the same request will be routed in the Semantic Link Network according to the service link type and semantic matching . Compared with previous P2P service discovery approaches , the proposed approach has two advantages : ( 1 ) produce more accurate and meaning results when searching for particular services in a P2P network ; and ( 2 ) enable users and peers to discover services in a more flexible way .
