A discovery method for usability-based semantic Web services is presented to deal with the service selection in complex composite Web services. The useful composite Web services are discovered using a dynamic adaptive template under the considerations of semantic matching degree
and rules such as the usability of composite Web services that are formally defined through the quantification of the functional property and non-functional property of Web services. The most suitable Web service is obtained according to the ordered values of the usability quantification for all the services. A matching engine using the proposed rules has been applied to a prototype system. Experiment results show that the proposed discovery method can realtimely fulfill the selection of complex composite Web services. Moreover
the optimal service can be obtained based on the premise of finding more available Web services.
