摘要
文章基于新浪微博的真实移动社交互动数据,考虑了体现关系互动的社交关系强度和社交影响范围,以及体现信息互动的信息价值和信息传播控制力等四个影响因素来构建信任评估模型。利用熵权法计算得到各因素对用户信任度的贡献程度。最后,通过计算节点的用户信任度来统一量化用户信任,从而识别可信节点。
Based on the real mobile social interactive data of Sina Weibo,the social trust evaluation model is constructed by taking the intensity of social relations and the sphere of social influence,which embody relationship interaction,as well as the information value and information transmission control,which embody information interaction into account.Then,entropy weight method is used to calculate the contribution of each factor to users' trust degree.Finally,users' social trust is quantified uniformly by calculating the node users' trust degree in order to identify the trusted nodes.
