论文摘要
我们研究了Reddit的政治讨论中对唐纳德·特朗普的支持的出现。凭借近800万个订户，“ R/The_donald”是Reddit上最大的社区之一，也是特朗普支持者的主要枢纽之一。它是在唐纳德·特朗普（Donald Trump）开始总统竞选后不久创建的。通过仅使用2012年以来的数据，我们预测在2016年上次美国总统大选的一年成为唐纳德·特朗普的支持者。为了表征特朗普支持者的行为，我们借鉴了三种不同的社会学假设：同质，社会影响力和社会反馈。我们将每个假设作为每个用户的一组功能，并训练分类器来预测其参与R/The_donald。 我们发现，基于同质和社会反馈的功能是最预测的信号。相反，我们没有观察到社会影响力机制的强烈影响。我们还进行了表现最佳模型的内省，以建立唐纳德·特朗普在雷迪特的典型支持者的“角色”。我们发现有证据表明，最杰出的特征包括男性利益的占主导地位，保守派和自由主义的政治倾向，以及与政治上不正确和阴谋的内容联系在一起。
We study the emergence of support for Donald Trump in Reddit's political discussion. With almost 800k subscribers, "r/The_Donald" is one of the largest communities on Reddit, and one of the main hubs for Trump supporters. It was created in 2015, shortly after Donald Trump began his presidential campaign. By using only data from 2012, we predict the likelihood of being a supporter of Donald Trump in 2016, the year of the last US presidential elections. To characterize the behavior of Trump supporters, we draw from three different sociological hypotheses: homophily, social influence, and social feedback. We operationalize each hypothesis as a set of features for each user, and train classifiers to predict their participation in r/The_Donald. We find that homophily-based and social feedback-based features are the most predictive signals. Conversely, we do not observe a strong impact of social influence mechanisms. We also perform an introspection of the best-performing model to build a "persona" of the typical supporter of Donald Trump on Reddit. We find evidence that the most prominent traits include a predominance of masculine interests, a conservative and libertarian political leaning, and links with politically incorrect and conspiratorial content.
