A Novel Web Service QoS Model based on Xml Query Optimization
With the proliferation of Web services, quality of service (QoS) becomes a key factor to differentiate the Web services and their providers. The definition of QoS model is nonuniformity, different developers define various QoS model by their style. Such problem bring out the difficult for service reuse.in this paper, we present a Web services QoS model which takes non-functional properties into account in various aspects. In this model, Web services qualities are classified into muti-dimension class. Web service QoS metrics are evaluated dynamically according to the service contextand the overall QoS is evaluated from multiple metrics according to a ~onfigurable fuzzy synthetic evaluation system.At last, the analysis of a case and the quality testing result shows that the QoS model achieves the result that we expect in great measure.
