摘要
针对微博用户信息传播能力,提出一种基于SNA(社会网络分析)的分析方法。以微博关注用户的数量为基础分析数据,建立微博用户的SNA整体网络和局部网络结构模型,通过中心度、核心边缘、社区派系分析,从微博用户信息传播链接渠道方面对微博用户的信息传播能力进行评估,即识别出位于微博社区内具有强信息传播能力的核心用户群和信息传播能力弱的边缘用户群。采用某一微博社区的样本数据验证了建模和评价方法的正确性和有效性。
Considering the microblog user information dissemination capacity, a SNA（social network anal-ysis）-based analytical approach was proposed. Based on analysis of data concern the number of users ofthe microblog, the structure models of microblog SNA overall network and local network are built, and byanalyzing the Center degrees, Core-periphery, Community cliques, the blogger＇s information dissemina-tion capacity could be evaluated from the aspect of blogger＇s information dissemination connections. Asresult, the core microblogs group, those being of high information dissemination ability, and limbic microb-logs group, those being of weak information dissemination ability, could be got the recognized. Takingsome microblog community data as testing sample data, the correctness and effectiveness of this modelingand evaluation method were verified.
