极端推特用户的社会网络:一个案例研究

Social Network of Extreme Tweeters: A Case Study

Xiuwen Zheng, Amarnath Gupta

摘要:

在任何给定的时间间隔内,单个用户帐户在社交媒体平台Twitter上发布的帖子数量通常很低。然而,有一部分用户的帖子量远远高于中位数。在本文中,我们调查的内容多样性和这些极端用户和其他人的社会邻里。我们定义了一个度量标准,称为“兴趣狭窄”,并确定一个极端的用户,称为异常用户的子集,写非常低的主题多样性的帖子,包括没有文本内容的帖子。使用一些互动模式,我们发现,异常组有最强的组内互动,他们与他人的互动相比。此外,他们表现出不同的信息共享行为与其他异常用户相比,非异常极端高音。

英文摘要:

The number of posts made by a single user account on a social media platform Twitter in any given time interval is usually quite low. However, there is a subset of users whose volume of posts is much higher than the median. In this paper, we investigate the content diversity and the social neighborhood of these extreme users and others. We define a metric called "interest narrowness", and identify that a subset of extreme users, termed anomalous users, write posts with very low topic diversity, including posts with no text content. Using a few interaction patterns we show that anomalous groups have the strongest within-group interactions, compared to their interaction with others. Further, they exhibit different information sharing behaviors with other anomalous users compared to non-anomalous extreme tweeters.
