Web Service Discovery Based on User Requirements

With the rapid development of Web services, Web service discovery becomes a significant challenge in the matching precision and efficiency. In this paper, we present a novel method in the view of users´ requirements for Web Service discovery. We set up the requirement model firstly, so as to present users´ requirements in details, then cluster the Web Services due to users´ common requirements, and obtain corresponding Web services´ QoS values. Thus, users can find their really needed Web services in an ordered list. The case study indicates the effect of our method, namely, in the view of users´ requirements, we sort the candidate Services due to their functions and their QoS attributes in descending order.
