提出了一个基于服务Agent的计算框架,并从社交认知的角度建立了一个服务Agent的信任本体,支持服务Agent对信任信息进行推理.根据该信任本体,提出一系列基于信任推理的计算规则支持信任值的计算,帮助服务Agent进行理性的选择决策.案例研究结果表明,该方法能够有效地帮助服务请求方进行信任评价以及服务选择.%This paper addresses the service selection issue via a service agent framework coupled with a computational model based on trust ontology. The trust ontology proposed from the socio-cognitive view can offer a more insightful understanding in the trust relationships among service agents. A set of trust computational rules have been given to support the trust analysis and reasoning. Also the structure of the service agents has been given. Finally, a case study is used to illustrate how the service agents infer the trustworthiness of their partners by using the set of trust reasoning and computational rules.
