摘要

通过服务直接交互中的服务行为来建立SC与SP实体的信任推理、演化及对SP实体的QoS评价模型。该模型基于概率密度函数来表征服务实体间的信任度

提出了基于概率密度信任关系的计算、推理及合并的演化方法

并给出了依据信任推理与QoS修正的服务评价算法。实验结果表明该方法能有效评价服务参与者的信任度

削弱不可信的实体对服务评价的影响

提高服务选择过程的质量及准确性。

Abstract

The credibility reasoning and deducing of SC and SP were proposed

which were mainly in the direct trust re-lationship established in interactive process among service entities

the public credibility of the feedback system as a sup-plement.The model used probability density function to represents the credibility of entities based on probability theory

which systematically proposed the reasoning and deducing methods of computing

reasoning and merging based on trust relationship in probability density.Then a new method of correcting QoS of SP entities was provided.Finally

the algo-rithm based on trust reasoning and correcting of QoS service was provided.This model can effectively evaluate the credi-bility of service participants

weakening the influence of unreliable entities in service evaluation and enhancing the quali-ties and accuracy of result in service selection through simulated experiment.
