A QoS evaluation method for personalized service requests

Abstract

With the prevalence of Web service, QoS is playing a more and more important role in service evaluation, recommendation and selection. In most previous works, it is often assumed that the delivered QoS of a Web service is often determined by service provider, not service consumer. However, in the practical service execution environment, Web services usually work in an interactive mode with service consumer, so service consumer should also take responsibility for the delivered QoS of a Web service. Hence, it becomes a challenge to evaluate the QoS of Web services impartially. In view of this challenge, a QoS evaluation method for personalized service requests is proposed in this paper. Finally, the effectiveness of our method is validated, and an optimization method is proposed to improve the QoS evaluation efficiency. © 2011 Springer-Verlag.
