摘　　要：针对移动终端用户上网时的信息健康问题,提出一种基于模糊理论的网站信任度综合评价模型。模型在模糊综合评价法的基础上引入了网站类型,网站类型采用SVM分类器来确定,根据类型选择评价因素集和评价权重。最后对评价结果进行模糊判决,由判决结果决定是否允许用户与网站交互。此外,该模型会结合历史评价记录确定评价的执行时间点。演算实例表明,模型符合实际情况,对网站的信任度评价起到了针对性作用,结果可靠性高,同时有效地缩短了网页平均响应时间和评价中的时间开销。Mobile end-user often experience information health problems when accessing the website. Aiming at this problem,a compre-hensive evaluation model for website trust based on fuzzy theory is proposed. The model introduces the types of sites and historical evalu-ation records based on fuzzy comprehensive evaluation method,using SVM classifier to determine the type of website,then it selects the evaluation factors and evaluation weight based on the type. Finally decide whether to allow the user to interact with the site according to the results of fuzzy decision. In addition,the model will be combined with historical records to determine the execution time of evaluation. Calculation examples show that the model in line with the actual situation,plays a specific role in the trust evaluation of website. The model has high reliability results while effectively reducing the average waiting time and user evaluation time overhead.
