QoS-aware Web services optimize selection based on reputation model
Decai Wang · Journal of Computer Applications · 2008
With the rapid development and wide application of Web service technologies,large growth in number of Web services as well as the growth in the number of registries makes this replication impractical.one of the main problems is that,how to select the optimal services from a set of requirements satisfying services in Web services composition.In practice a model for Web service discovery and selection based on Quality of Service(QoS) constraints is cannot cope with such kind of request s very well.A method to select the optimal Web services in composition based on reputation was proposed.First,the subjective reputation values based on the workflow organization model were computed,and then the objective quality values using the QoS model were computed,at last,users can select the optimal Web services by combing the two values as the judgment standard.
