Abstract:
This paper proposes a trust model based on Dirichlet distribution in Multi-Agent System(MAS). It uses the Dirichlet distribution to solve the limitations of a binary evaluation, the trust model can rate with graded levels. A level filtering algorithm is proposed to effectively filter a variety of malicious Agent in the referrals. Experimental results show that the proposed trust model is effective in inhibiting unfair recommendations and strategies deception.

摘要:
提出一种多Agent系统中基于狄利克雷分布的信任模型。该模型利用狄利克雷分布解决二元评价的局限性,使信任模型可以按等级来评价信誉。提出层次过滤算法,以解决推荐信息中存在的各类恶意Agent问题。仿真实验结果表明,该信任模型能有效抑制不诚实推荐和策略性欺骗。
