Research on Similarity-Based Semantic Web Services Discovery

Aiming at the problems of low efficiency in service discovery of traditional web service, a similarity-based semantic web service discovery model is proposed, with the application of semantic web technology and ontology. The mechanism uses Ontology Web Language for Service (OWL_S) to describe web service and publishes service with semantic information. Ontology reasoning is added into service searching to measure its degree of functional matching and reputation value. The experiments suggest that the proposed method is better than that of Universal Description Discovery and Integration (UDDI) in precision and recall ratio.
