Relevancy Ranking of Web Services

In order for Web services to truly become a standard approach for just-in-time application integration, we need to enhance the discovery mechanism by assisting clients to select relevant Web services of interest. In recent years, there have been several standards that regulate how services can be published, discovered, or used (i.e. UDDI, WSDL, SOAP). Many of these standards have the potential of enhancing the discovery process, however, there are major technical challenges associated with these standards. One of these challenges is the client´s ability to control and manage the discovery process for finding Web services of interest. Clients should be able to find relevant services much more efficiently. To address this issue, we propose a Web service ranking (WSR) algorithm for measuring the relevancy of Web services to particular clients´ requirements. This paper presents experimental validation, results and analysis of the presented ideas.
