摘　　要：【目的】微博个体信息传播影响力评价常用转发数作为唯一标准,面对如利用"购买粉丝"增加转发数的个体时,评价结果无法反映真实的传播影响力。【方法】从传播效果角度,引入并重新定义传播深度、传播速度两种传播效果特征并给出量化方法,结合转发数(传播广度)共同作为传播影响力评价维度,在此基础上融合构建微博个体信息传播影响力评价模型。【结果】实验结果表明相比转发数,新模型能真实反映个体信息传播影响力,尤其可以区分转发数相同情况下个体间信息传播影响力的差异。【局限】实验数据利用新浪微博API获取,API返回数据多少存在限制。为获得完整的传播数据,实验选取信息转发数低于2 000次的个体。但模型本身不受传播数据大小的影响,使用时保证数据完整即可。【结论】提供一种新的、更为准确的个体信息传播影响力评价模型,具有较强的理论和实用价值。[Objective] Forwarding number is usually as the one and only criterion in Micro-blog individual evaluation of information dissemination influence. When individual increases forwarding number using ＇buying fans＇, evaluation result can＇t reflect its true influence. [Methods] From the perspective of dissemination results, this paper redefines propagation depth, speed and gives quantitative methods, combined with the forwarding number （propagation breadth） together as evaluation dimensions, constructs evaluation model based on dimensions. [Results] Experimental results show that compared forwarding number, the new model can truly reflect the individual information dissemination influence, in particular, can distinguish the difference between individuals with the same forwarding number. [Limitations] Experimental data is obtained by using Weibo API, but how much data returned is limited. To get the full dissemination of data, the experiment selects individuals that forwarding number of its information is lower than 2 000. But the model is not affected by data size, while data integrity should be ensured for using. [Conclusions] This paper provides a new, more accurate information dissemination influence evaluation model with strong theoretical and practical value.
