摘要:

在过去几年中,我们观察到不同的媒体试图通过构建信息来支持有利于其目标的叙事,从而改变公众舆论。被称为“致病性社交媒体”(PSM)账户的恶意用户更有可能通过传播错误信息来放大这种现象。因此,从会计层面理解错误信息的传播是一个紧迫的问题。在这项工作中,我们的目标是提出一个功能驱动的方法来检测PSM帐户在社交媒体。受文献的启发,我们从三个广泛的角度出发评估PSM:(1)用户相关信息(例如,用户活动,简档特征),(2)源相关信息(即,经由用户共享的URL链接的信息)和(3)内容相关信息(例如,tweets特征)。对于用户相关信息,我们使用因果关系分析来调查恶意信号(即,如果用户经常是病毒级联的原因)和简档特征(例如,追随者的数量等)。对于源相关信息,我们探索链接到URL的各种恶意属性(例如,相关网站的URL地址、内容等)。最后,对于与内容相关的信息,我们检查属性(例如,标签的数量、可疑标签等)来自用户发布的推文。来自不同国家的真实Twitter数据上的实验证明了该方法在识别PSM用户方面的有效性。

英文摘要:

Over the past few years, we have observed different media outlets' attempts to shift public opinion by framing information to support a narrative that facilitate their goals. Malicious users referred to as "pathogenic social media" (PSM) accounts are more likely to amplify this phenomena by spreading misinformation to viral proportions. Understanding the spread of misinformation from account-level perspective is thus a pressing problem. In this work, we aim to present a feature-driven approach to detect PSM accounts in social media. Inspired by the literature, we set out to assess PSMs from three broad perspectives: (1) user-related information (e.g., user activity, profile characteristics), (2) source-related information (i.e., information linked via URLs shared by users) and (3) content-related information (e.g., tweets characteristics). For the user-related information, we investigate malicious signals using causality analysis (i.e., if user is frequently a cause of viral cascades) and profile characteristics (e.g., number of followers, etc.). For the source-related information, we explore various malicious properties linked to URLs (e.g., URL address, content of the associated website, etc.). Finally, for the content-related information, we examine attributes (e.g., number of hashtags, suspicious hashtags, etc.) from tweets posted by users. Experiments on real-world Twitter data from different countries demonstrate the effectiveness of the proposed approach in identifying PSM users.
