十多年来,社交媒体一直在改变政治交流的动态。在这里,我们使用近10亿条推文,分析了2016年至2020年美国总统大选期间推特新闻媒体格局的变化。使用政治偏见和事实核查工具,我们测量了政治偏见内容的数量和传播此类信息的用户数量。然后,我们确定影响者——在Twitter网络中传播新闻能力最强的用户。我们观察到,2016年至2020年期间,虚假和极端偏见内容的比例有所下降。然而,结果显示,在用户和影响者层面,两场选举的回声室行为和潜在的意识形态两极分化都在增加。Flamino等人研究了2016年至2020年美国总统大选期间政治新闻媒体和推特网红格局的变化。
Social media has been transforming political communication dynamics for over a decade. Here using nearly a billion tweets, we analyse the change in Twitter’s news media landscape between the 2016 and 2020 US presidential elections. Using political bias and fact-checking tools, we measure the volume of politically biased content and the number of users propagating such information. We then identify influencers—users with the greatest ability to spread news in the Twitter network. We observe that the fraction of fake and extremely biased content declined between 2016 and 2020. However, results show increasing echo chamber behaviours and latent ideological polarization across the two elections at the user and influencer levels. Flamino et al. examine changes in the political news media and influencer landscape of Twitter between the 2016 and 2020 US presidential elections.
