摘要: 信任本身是一个社会认知的概念,因此从认知的角度来研究信任是合适的。通过引入时间认知,建立一种基于时间顺序标码(TSM)的信任评价的概念模型。在分析了经验信息的三种遗忘效应(即距离效应、边界效应以及层级效应)后,将其应用到个体信任值的计算中。在概念模型的基础上,采用D-S信度理论来建立信任的可计算模型。对比了理论与实验结果,表明该模型是有效的。

Abstract: Trust itself is a social cognitive concept, so it is fit to research trust from cognitive view. A conceptual model based on Temporal Sequential Marker (TSM) was proposed after introducing time cognition. Furthermore, three different kinds of forgetting effects (distance effect, boundary effect and hierarchical effect) were considered for the computing of TSM-trust of each individual. D-S theory was exploited to build up a computational dynamic trust (TSM-Trust) model based on the proposed conceptual model. The proposed model was verified through comparison of theoretical results and experimental results.
