The growing popularity of online social networks has opened the door to false information being disseminated by malicious actors. Hostile nation states are orchestrating disinformation campaigns in the United States with the goal of influencing public discourse or pushing talking points that favor a particular country’s agenda. These campaigns are typically carried out with the help of fake social media accounts known as trolls, which pose as fictitious personas. These trolls interact with each other and with unsuspecting social network users with the goal of polarizing discussion and furthering false narratives. Despite the serious threat that disinformation poses to our society, social networks are struggling to keep up with the threat, resorting to reactive measures that remove malicious accounts after the fact. The goal of this project is to develop techniques able to automatically identify troll accounts on social networks so that they can be more swiftly removed.To carry out this project, the investigators are collecting information about the troll accounts identified by Twitter and Reddit as belonging to several foreign countries’ disinformation campaigns. These data are used to train machine learning algorithms able to automatically identify other troll accounts on Twitter and Reddit. The project follows two parallel research tasks. In the first task, the research team aims to train supervised learning algorithms to learn the typical behavior of known troll accounts, with the goal of identifying more accounts that behave similarly and are therefore part of the same disinformation campaign. Preliminary results show that troll accounts exhibit peculiar interaction patterns that are uncommon in real accounts. In the second task, the researchers will work towards identifying traits that are typical of troll accounts regardless of the campaign that they belong to, and use transfer learning techniques to identify emerging disinformation campaigns. Students are involved at all stages of the research.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在线社交网络的日益普及为恶意演员传播的虚假信息打开了大门。敌对的民族国家正在策划美国的虚假宣传运动，目的是影响公众话语或推动有利于特定国家的阿格恩达的谈话要点。这些运动通常是在被称为巨魔的虚假社交媒体帐户的帮助下进行的，这些帐户构成了虚构的角色。这些巨魔相互互动，并与不可思议的社交网络用户进行两极分化的讨论和进一步的虚假叙述。尽管虚假信息对我们的社会构成了严重的威胁，但社交网络仍在努力跟上威胁，诉诸于事实后消除恶意帐户的反应性措施。该项目的目的是开发能够自动识别社交网络上的巨魔帐户的技术，以便可以更快地删除它们。要执行该项目，调查人员正在收集有关Twitter和Reddit确定的巨魔帐户的信息，并属于几个外国国家的虚假信息。这些数据用于训练机器学习算法可以自动在Twitter和Reddit上识别其他巨魔帐户。该项目遵循两个并行的研究任务。在第一项任务中，研究小组旨在培训监督的学习算法，以了解已知巨魔帐户的典型行为，目的是确定更多相似行为的帐户，因此是同一虚假信息运动的一部分。初步结果表明，巨魔帐户展示了真实帐户中罕见的奇特交互模式。在第二任任务中，研究人员将致力于确定巨型帐户典型的特征，而不论其属于运动，并使用转移学习技术来识别新兴的虚假信息运动。该奖项反映了NSF的法定任务，并通过基金会的知识分子优点和更广泛的影响评论标准评估来反映了NSF的法定任务。
