> 中文摘要: 借助人类社会中的信任行为特征以及自然科学中的万有引力定律,提出了信任引力概念,并基于此分析普适环境中交互实体间的信任关系.同时,建立了一个合理的基于信任引力的服务评价和选择模型,通过直接评价、间接评价、历史评价等多角度综合评估有效地提高服务选择效率和准确性.实验结果表明,利用该模型,普适实体能在较短时间内准确地选择一个最优服务实体.
Abstract:Based on trust behavior experience in human society and the law of gravity,this paper introduces a concept of trust gravitation to analyze the trust relationship between pervasive interaction entities. Then built a sound svstem is built in terms of a service evaluation and selection model based on trust gravitation. The system that integrated direct,indirect and historic evaluation is tested to improve the efficiency and veracity of service evaluation and selection.Experimental results show that pervasive entities can select optimum netWork services in short time via of this model.
