公益机构微博社会网络中心性分析

A preliminary Analysis of Social Network Centrality in Public Welfare Micro-blogs

应用社会网络分析法,以腾讯微博为平台,以认证公益机构微博为样本,分析公益机构与微博之间互相关注的关系信息及"权利"。从点度中心性、中间中心性、接近中心性三方面的分析可以看出,不同的机构微博在信息获取与发布、信息走向控制上的权利及影响力有很大的差别,微博数值越高者相应的"权利"越大。

With social network analysis as its approach, Tencent micro-blog as its platform, accredited public micro-blog institutions as samples, this paper aims to explore the mutual concerned information and right amongst those public micro-blog institutions. From the following three perspectives of degree centrality, betweenness centrality, closeness centrality proposed by Freeman, this paper maintains that different institutional micro-blogs differ greatly in information access and release, information control and influence.
