对组合服务信任度评估问题进行了研究.基于信任的不确定性和模糊性,给出了信任度的离散化表示方法;借助于贝叶斯网络的强大的推理能力,给出了组合服务的贝叶斯网络模型以及组合服务模型到贝叶斯网络的转换规则,利用贝叶斯网络的正向推理机制设计了基于贝叶斯网络模型的组合服务信任度评估方法.通过一个组合服务的实例,说明了组合服务的贝叶斯网络模型及其基于贝叶斯网络的组合服务信任度评估方法的使用方法.该评估方法基于信任的模糊性和不确定性,更符合信任的本质并易于实现.

The trust degree evaluation problem is researched in this paper. Based on the uncertainty and fuzziness of trust, a method for discrete presentation of trust is proposed. With the powerful inference ability of Bayesian networks, the Bayesian network model for composite service is presented and the rules for translation of the composite service model to Bayesian networks are designed. The trust degree evaluation method for composite services based on the forward reasoning mechanism of Bayesian networks is designed. The using method of the Bayesian network model and the evaluation method is illustrated by a composite service example. Because the trust degree evaluation method is based on uncertainty and fuzziness of trust concept, the method is true of essence of trust and easy to implement.
