新浪微博中的“权威”与“人气”:以社会网络分析为方法

Authority and Popularity:Social Network Analysis on Sina Microblogging

本文以新浪微博"时尚"标签下的用户作为研究样本,基于样本用户间以及整个新浪微博用户间的关注关系分别构建了"相互关注"网络与"共同关注"网络,运用社会网络分析法揭示了微博中该标签领域的权威人物及网络成员之间的关系,并进一步对比分析了"相互关注"和"共同关注"的网络属性差异以及差异产生的原因。此外,本文还分析了表征人气的粉丝数、博文转发数、博文评论数这三个指标之间的相关性及其与社会网络分析指标的相关性,对微博核心用户的确定问题进行了讨论。
