Novel QoS-aware Web service recommendation model

A service register center provides a set of services with equivalent functionality,and further the QoS of these services usually collected from different users. The ability of providing best service for a specific user is critical in SOA. This paper proposed a QoS-aware Web service recommendation model. It employed a user’s context-aware component,so that the problem of the inconsistent between user’s experience of service QoS and the QoS information provided by service register center was smoothed. It also employed analytical hierarchy process to model user’s QoS preferences and evaluate the candidates of service. The soundness of context-aware component was tested in the experiment,and gave an example of service recommendation for illumination.
