A Social Trust Based Recommendation Mechanism for Web Service Dynamic Collaboration

In the distributed commercial environment, many enterprises utilize Web services to provide their resources such as data and applications to consumers. They collaborate with other relevant enterprises to accomplish tasks by sharing processes and resources. However, it is difficult to find the appropriate web service combination for enterprise, because the Quality of Services (QoS) that are widely used to select Web services is not sufficient anymore. In dynamic collaboration environment, it does not only need to consider the QoS, functionality and degree of matching, but also the social trust relationship between enterprises. This study proposes a social-trust-based recommendation mechanism for service-oriented dynamic collaboration. It uses the legal binding of Service Level Agreement and the characteristics of Social Trust Network of Web services to recommend proper and trustworthy services to support dynamic collaboration.
