Abstract:
The credibility of web service often plays an important role for service-oriented applications.Integrating and assessing different sources of trust is a challenge.In this paper,we present a method of web service reliability assessment based on QoS and reputation.We not only incorporate many sources of trust,but also assess the web service’ trust.Firstly,we integrate direct trust with multi-QoS of web services and the historical trust of the users and services.At the same time,the reliability of direct trust is improved through the addition of the attenuation factor to weaken the influence of the historical trust to the direct trust.Secondly,we present the concept of reputation and establish trust assess mechanism between users.Then recommended trust is divided into acquaintances’ indirect recommendation trust and strangers’ direct recommendation trust,so as to make the recommendation trust value more comprehensive and credible.The method is proved to be better than other service’s trust model in time and space complexity.The result of example indicates that the proposed method can be used to solve the trusted web service selection,and guarantee the accuracy of the trust.
