摘要:
Web服务的可信性往往对面向服务的应用起决定性作用.由于服务的信任信息来源很多,整合多种来源的服务信任信息,准确地评估服务的可信性是一个挑战.针对这一挑战,提出了一种基于QoS和声誉的服务信任度评估方法.与其他服务信任度评估模型相比,本模型融合了多个信任信息来源,在直接信任度中综合了QoS和用户对服务的历史信任,并加入时间衰减因子,逐渐削弱历史信任对直接信任度的影响,提高直接信任度的可靠性; 在推荐信任度中引入推荐者声誉概念,建立用户之间的信任评估机制,从而将推荐信任分为熟人推荐信任和陌生人推荐信任两类,使推荐信任的评估更加完整、准确.此外,本方法在时间和空间复杂度方面,也存在诸多优势.实例分析表明,本文提出的评估方法可以用来解决Web服务选择的可信问题,并且能够提高服务信任度评估的准确性.
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.
