Abstract—In order to select the proper one from the web service candidate sets which are provided by semantic matching, a method for web service selection with QoS (quality of service) constraints is proposed. In this paper, firstly, the Four-Level Matching Model for Semantic Web Service based on QoS Ontology, which includes Application Domain Matching, Description Matching of Service, Function Matching of Service and QoS Matching, is presented, then, the QoS ontology for web service is constructed and the QoS description information with the QoS concept in OWL-S (Web Ontology Language for Services) model is extended, thirdly, the extensible OWL-SQ model for service description with service semantic and QoS description is presented, and it is QoS supporting and constraining. Then based on decision theory and normalized algorithm, the dimensionless method of QoS properties for un-numerical value type and numerical value type in OWL-SQ model is proposed. Finally, the algorithm for constructing matching matrix of QoS and the service selection method are presented, to evaluate and select optimization candidate web service comprehensively. Test result shows that the efficiency and accuracy of service selection are improved with the service selection method based on OWL-SQ model.
