摘　　要：针对网络中主体信任评判问题,提出一种基于区间的主观信任模型。参考社会学中人际信任关系的"凸"型曲线,引入由专家评定的权重结果,借助主体评估因素结果的加权平均值对主体按计分方法进行建模,采用信任区间将主体的信任分为6个等级。实例分析结果表明,该模型能够对主体信任进行有效合理的评估。According to the evaluation of trust for the subject, a subjective trust model based on the interval is proposed. It refers to the convex curve of the interpersonal trust relationship in the sociology, and introduces the weights of expert evaluation, Learning from the weighted average of the evaluation on the subject, a model on the subject by scoring method is established. The trust of the subject is divided into six intervals by trust interval, and example analysis confirms the validity and rationality of the model which uses the trust interval to show the trust degree.
