Utilizing Web2.0 in Web Service Ranking

The current shift in realizing distributed applications by applying service-oriented principles translates into more and more web services being published on the Web each day. This introduces a set of new challenges such as how to organize, search, rank and select services. For ranking especially the use of any external information to the service, such as social information coming from Web2.0 sources has the potential to improve the accuracy of this task. In this paper we explore the idea of using social annotations technology for ranking web services. We show how such approach can be implemented using information provided by one of the largest social networks - del.icio.us.
