了解COVID-19大流行期间高度相关在线社区的用户轨迹差异

Understanding the Diverging User Trajectories in Highly-related Online Communities during the COVID-19 Pandemic

摘要:

随着COVID-19大流行扰乱全球生活,相关在线社区如雨后春笋般涌现。特别是Reddit上出现了两个“新”社区,/r/China flu和/r/Coronavirus,从这场大流行一开始就致力于COVID相关的讨论。随着/r/Coronavirus成为Reddit上的官方社区,用户如何在这两个高度相关的社区之间做出选择仍然是一个悬而未决的问题。在本文中,我们描述了从COVID-19开始到2020年9月底这两个社区的用户轨迹。我们发现,从1月到3月,/r/中国流感和/r/冠状病毒的新用户相似。此后,随着这一大流行病的继续发展,他们的分歧稳步扩大,这从语言距离和成员预测中可以看出。此外,从1月到3月开始使用/r/中国流感的用户更有可能离开,而那些在随后几个月开始使用的用户往往保持高度“忠诚”。为了理解这一差异,我们开发了一个移动分析框架,以了解这两个社区的成员变化,并确定在2月份转移到/r/Coronavirus的/r/China flu成员中有很大一部分(约50%)。根据用户以前活跃的其他子Reddit,这种移动是高度可预测的。我们的工作展示了两个高度相关的社区如何在危机中出现并发展自己的身份,并强调了现有社区在理解这种出现方面的重要作用。

英文摘要:

As the COVID-19 pandemic is disrupting life worldwide, related online communities are popping up. In particular, two "new" communities, /r/China flu and /r/Coronavirus, emerged on Reddit and have been dedicated to COVID- related discussions from the very beginning of this pandemic. With /r/Coronavirus promoted as the official community on Reddit, it remains an open question how users choose between these two highly-related communities. In this paper, we characterize user trajectories in these two communities from the beginning of COVID-19 to the end of September 2020. We show that new users of /r/China flu and /r/Coronavirus were similar from January to March. After that, their differences steadily increase, evidenced by both language distance and membership prediction, as the pandemic continues to unfold. Furthermore, users who started at /r/China flu from January to March were more likely to leave, while those who started in later months tend to remain highly "loyal". To understand this difference, we develop a movement analysis framework to understand membership changes in these two communities and identify a significant proportion of /r/China flu members (around 50%) that moved to /r/Coronavirus in February. This movement turns out to be highly predictable based on other subreddits that users were previously active in. Our work demonstrates how two highly-related communities emerge and develop their own identity in a crisis, and highlights the important role of existing communities in understanding such an emergence.
