基于信息传播的微博用户影响力度量

Measuring user influence of a microblog based on information diffusion

信息传播和用户影响力度量是目前微博研究的基础和热点方向。为了定量地研究用户影响力,提出基于用户消息传播范围的用户影响力量化定义,并给出用户影响力的计算方法。在真实数据集上对算法的验证结果显示,与其他用户影响力度量方法相比,本文提出的方法计算复杂性低、指标稳定性高,尤其适合于需要限定数据集、限定时间段的具体应用场景。

Information diffusion and influence modeling are hot topics in microblog research.To do research on influence quantitatively,a concept based on the message diffusion was introduced and complied with how to count it out.The proposed approach was validated on real world datasets,and the result of experiments shows that our method is both effective and stable,especially in condition of limited dataset and time span.
