Research on Web Service Matching Algorithm Based on Semantic

The OWL-S/UDDI matching algorithm based on reasoning cannot differentiate the matching degree on the same results level,thus causing inaccuracy and incompleteness.According this shortcoming of reserch,this paper proposes a Web service matching algorithm based on similarity computing of ontology concept.The algorithm has three levels:the basic description matching,the function matching ,and the non-function matching(QoS).This algorithm can improves the efficiency of services matching.
