摘要
信任在人类社会的合作中起着非常重要的作用,在诸多领域也受到了广泛的关注。在开放多Agent系统(MAS)的研究中,引入了信任的方法,用于解决交互伙伴的选择问题。信誉与信任密切相关,可以视信誉为信任的信息来源之一,信誉系统是用于完成信任评价的机制。MAS中信任研究应担负起发现计算实体之间信任的一般规律的重任。讨论了信任和信誉模型研究的内容、要求以及应用。在技术层面,信任表示有认知和数值两种观点,形成了集中式、分布式和混合式的体系结构,用于信任的汇总包括统计、概率、信念理论及模糊推理等方法。群体信誉、信息不准确、信息贫乏、异构模型互操作等问题有待进一步深入研究。
Trust plays an important role in the interaction of human society,and is focused on in many related research domains.Trust is also introduced to open multi-agent system to help agent choose interaction partner.Reputation can act as one of sources of trust information,which is closely related to trust.Reputation system is a mechanism to evaluate trust in MAS.Research on trust in MAS should take on responsibility of finding the general law of trust among computational entities.The content,requirements and applications of trust and reputation system were discussed in the paper.In terms of technology,there are cognitive and numerical opinions in trust representation,and centralized,distributed and mixed frameworks were adopted by the reputation system.The statistics,probability,belief theory and fuzzy rea-soning methods were used to aggregate reputation information.At last,some problems were put forward to study further in the future,which cover group reputation,inaccurate report,lacking of information and interoperation between heterogeneous reputation systems.
