摘要

社交媒体提供了公民的声音,引发了基层集体行动,用户齐心协力传播在线叙事,甚至进行线下抗议。有时,这些集体行动得到无机同步的帮助,这是由bot参与者产生的。因此,确定社交媒体上新兴话语的同步性以及对话中有机/无机活动的迹象是很重要的。这提供了一种分析事件是否可能发生线下抗议和暴力的方法。在本研究中,我们以过去对社交媒体同步活动的定义为基础——同步用户行动,并开发了一个联合同步指数(CSI),该指数采用分层方法来衡量用户同步性。我们将该指数应用于Twitter上的六个政治和社会活动事件,并分析了三种行动类型:标签、URL和@提及的同步性。CSI提供了一个事件中所有操作类型之间同步的总体量化,它允许对六个事件之间的同步度进行排序。在大多数事件中,人类用户的同步得分高于机器人用户;与其他配对(即bot-bot和human-human)相比,bot和human在所有事件中表现出最同步的活动。我们进一步依靠CSI-Network得分与网络中心性指标的和谐与不和谐来观察有机/无机同步的存在。我们希望这项工作有助于以集体方式调查社交媒体中的同步行动。

A combined synchronization index for evaluating collective action social media.

Social media has provided a citizen voice, giving rise to grassroots collective action, where users deploy a concerted effort to disseminate online narratives and even carry out offline protests. Sometimes these collective action are aided by inorganic synchronization, which arise from bot actors. It is thus important to identify the synchronicity of emerging discourse on social media and the indications of organic/inorganic activity within the conversations. This provides a way of profiling an event for possibility of offline protests and violence. In this study, we build on past definitions of synchronous activity on social media- simultaneous user action-and develop a Combined Synchronization Index (CSI) which adopts a hierarchical approach in measuring user synchronicity. We apply this index on six political and social activism events on Twitter and analyzed three action types: synchronicity by hashtag, URL and @mentions.The CSI provides an overall quantification of synchronization across all action types within an event, which allows ranking of a spectrum of synchronicity across the six events. Human users have higher synchronous scores than bot users in most events; and bots and humans exhibits the most synchronized activities across all events as compared to other pairs (i.e., bot-bot and human-human). We further rely on the harmony and dissonance of CSI-Network scores with network centrality metrics to observe the presence of organic/inorganic synchronization. We hope this work aids in investigating synchronized action within social media in a collective manner.
