Research on semantic based distributed service discovery in P2P environments/networks

Abstract

In order to reduce the network communication cost of the discovery of distributed services and improve the search efficiency and recall performance, researchers put forward a distributed service discovery strategy based on semantic in P2P environment. Firstly, they constructed an ontology model to describe the types of services, and then located the starting point of the search process on the associated Peer node based on semantic service classification. Secondly, a double layer parallel service discovery method was put forward. In UDDI layer, they used the classic keyword matching to search services in UDDI center. In the semantic layer, researchers used the semantic query and reasoning on the service ontology model. Finally, the performance of the proposed method was verified by experiment. © 2013 Springer Science+Business Media New York.
