Provision of semantic web services through an intelligent semantic web service finder

摘要

This paper shows a searching mechanism to discover Semantic Web Services satisfying client requirements. The increase in web services and lack of semantic base in search mechanisms of UDDI make it difficult for clients to find a required web service. We developed a system which uses a Semantic Search Agent (SSA) to discover suitable web services according to client requirements then presents them as a result page. The system uses Ontology Web Language for Services (OWL-S), which allows semantic description of web services. Hence, the SSA is able to understand predefined features of Semantic Web Services, extract necessary information, and decide on which services would meet the service requirement of a client. The system retargets and combines complimentary aspects of two research topics (Smart Web Query Engine and Matchmaking Algorithm of OWL-S/UDDI Matchmaker) to facilitate the provision of web services to a client.
