Toward Trust and Reputation Based Web Service Selection: A Survey

Using trust and reputation mechanisms offers a promising way to solve the web service selection problem. The investigation of trust and reputation systems in other areas can provide valuable observations and approaches that can be used in web service systems. Therefore, this paper presents a systematic review of various trust and reputation systems and proposes a typology to classify them from three aspects, centralized vs. decentralized, persons/agents vs. resources, global vs. personalized. These aspects are important not only in that they clarify the difference between various existing trust and reputation systems, but also in that they point out the potential research directions for using trust and reputation in web services and provide some reference systems for them
