摘要
研究分布网络环境中主观信任评价和信任合成方法,分析信任的含义和影响信任行为的因素以及信任与信任属性的关系,提出相对经验的定义.基于二项事件后验概率服从Beta分布的特性,提出了基于相对经验和Beta分布的信任评价模型,给出了推荐信任合成方法,建立信任更新协议解决恶意推荐的问题.
<Abstrcat> To solve the complex and dynamic trust relationships in distributed network, subjective trust model is proposed. Trust quantification and propagation methods are investigated. The meaning of subjective trust and the factors influencing trust behavior are discussed. The relationship of trust and trust attributes is investigated. A definition of relative experiment is presented. Based on the definition and Beta distribution, a novel subject trust model is proposed, and an algorithm to combine recommendation trust is illustrated. The trust updating protocol is presented to adjust trust relationship.
