该文主要研究在微博社交网络中怎样评价用户的影响力。在影响用户影响力的众多因素中,该文认为用户的传播能力越强,用户的信息便可以更快地在网络中扩散,其影响力也越大。和传统的用户影响力评价方法相比,该文综合考虑用户的活跃度和用户所发微博质量两个方面的因素,得到用户的影响力权重,然后把每一个用户作为社交网络中的节点,计算其在社交网络中的影响力。通过在公开语料集和真实数据中的实验,表明该方法是可行的,比传统的用户影响力评价方法更能客观、真实地反映用户的实际影响力。
Abstract
This paper investigates the evaluation of the user influence on Sina microblog. Among various factors, a user is considered as more influential if his information is disseminated faster to a larger extent. Compared with traditional methods, the user's active degree and the quality of posts are both taken into consideration. Treating each user as a node in the social network, the final user influence is estimated. The experiments on both public dataset and real dataset from Sina microblog show the validity of the method.
