红色机器人做得更好:社交机器人党派行为的比较分析

Red Bots Do It Better: Comparative Analysis of Social Bot Partisan Behavior

Luca Luceri, Ashok Deb, Adam Badawy, Emilio Ferrara

摘要:

最近的研究使人们意识到社交媒体上的机器人问题以及在政治讨论背景下大规模操纵舆论的重大风险。在这项工作中,我们利用Twitter来研究2018年美国中期选举期间的话语,并分析社交机器人活动和与人类的互动。在选举日前后的42天里,我们从近100万用户那里收集了260万条推文。我们使用收集的推文来回答三个研究问题:(i)社交机器人是否根据政治意识形态进行倾斜和行为?(ii)我们能观察到自由派和保守派机器人之间的不同策略吗?(iii)机器人策略有多有效?我们表明,社交机器人可以根据他们的政治倾向准确地分类,并相应地采取行动。保守的机器人与人类机器人分享大部分讨论的话题,而自由的机器人则表现出较少的重叠和更具煽动性的态度。我们研究了机器人与人类的互动,并观察了不同的策略。最后,我们测量了机器人在社交网络中的嵌入性及其活动的有效性。结果表明,保守的机器人在社交网络中嵌入得更深,在对人类施加影响方面比自由的机器人更有效。

英文摘要:

Recent research brought awareness of the issue of bots on social media and the significant risks of mass manipulation of public opinion in the context of political discussion. In this work, we leverage Twitter to study the discourse during the 2018 US midterm elections and analyze social bot activity and interactions with humans. We collected 2.6 million tweets for 42 days around the election day from nearly 1 million users. We use the collected tweets to answer three research questions: (i) Do social bots lean and behave according to a political ideology? (ii) Can we observe different strategies among liberal and conservative bots? (iii) How effective are bot strategies? We show that social bots can be accurately classified according to their political leaning and behave accordingly. Conservative bots share most of the topics of discussion with their human counterparts, while liberal bots show less overlap and a more inflammatory attitude. We studied bot interactions with humans and observed different strategies. Finally, we measured bots embeddedness in the social network and the effectiveness of their activities. Results show that conservative bots are more deeply embedded in the social network and more effective than liberal bots at exerting influence on humans.
