微博关注网构建与统计分析研究

摘要

We use the data of microblogging users as the source of social media data and construct a microblog -concerned network based on the mutual concern relationships between the microblogging users , then we make a fine-grained analyse on the attributes of the user nodes in the constructed concerned network and on the characteristic of the network structure by means of social network analysis and data statistical analysis technology , and summarise the basic feature of such virtual groups in form of microblog .The main conclusions include four points:(1) The objects concerned by the microblogging users are closely correlated to the regions where the users are living ;(2) Those users to be at the heart of the microblogging users'circle often have more fans or possess the occupations attracting more attentions in the circle ;(3) The density of the concerned sub-network is quite high and the users are closely linked to each other;(4) The interactions among the microblog-ging users often occur in their own clique .%通过使用微博用户数据作为社会媒体数据来源，基于微博用户之间的相互关注关系构建出微博关注网。然后利用社会网络分析和数据统计分析方法，对所构建关注网的用户节点属性特征以及网络结构特征进行细粒度分析，并对微博这种虚拟群体的基本特征进行总结。主要结论包括：（1）微博用户所关注的对象与用户所在地域密切相关；（2）微博用户圈中处于核心地位的往往是粉丝数目较多的用户或是职业在该用户圈中较为受关注的用户；（3）关注子网的网络密度较大，用户之间的联系十分紧密；（4）微博用户之间的互动往往发生在其所属的派系之中。
