The technique of Web services enables the development of large-scale applications in open environments.The increasing number of Web service providers have produced numerous Web services providing the same or similar functionality,and this necessitates the use of tools and techniques to search Web services available over the Web.However,the majority of selection mechanisms are designed to use a fixed set of indicators as the selection criteria,so when dealing with unknown Web services,they are unable to adapt to the diverse demands of users.In this paper,considering the service provider's network and the service consumer's network,from the perspective of social network,we proposed a trustworthy service selection framework.The synthetic value of service provider was identified by fuzzy synthetic evaluation method and the reliability of Web services was calculated upon user ratings.User makes selection decision with demands of QoS,QoS data,the synthetic evaluation of service provider and the reliability of Web services.
