用于研究社交媒体中极化政治事件的用户建模管道

A User Modeling Pipeline for Studying Polarized Political Events in Social Media

Roberto Napoli, Ali Mert Ertugrul, Alessandro Bozzon, Marco Brambilla

摘要:

本文提出了一种用户建模管道,用于分析社交媒体上关于极化政治事件(例如,民意调查)。管道遵循四步方法。首先,抓取社交媒体帖子和用户元数据。其次,过滤机制被应用于过滤垃圾邮件发送者和僵尸网络用户。第三步,从有效用户中提取人口统计信息,即性别、年龄、种族和位置信息。最后,相对于所分析的事件的用户的政治极性进行预测。在这项工作的范围内,我们提出的管道应用于两个公投场景(西班牙加泰罗尼亚独立和意大利伦巴第自治),以评估该方法在收集社交媒体用户人口统计数据的正确见解以及根据用户共享的意见预测民意调查结果的能力方面的性能。实验表明,该方法是有效的预测加泰罗尼亚的情况下,但不是伦巴第大区的情况下的政治趋势。在各种各样的动机中,我们注意到,总的来说,Twitter更能代表反对公投的用户,而不是支持公投的用户。

英文摘要:

This paper presents a user modeling pipeline to analyze discussions and opinions shared on social media regarding polarized political events (e.g., public polls). The pipeline follows a four-step methodology. First, social media posts and users metadata are crawled. Second, a filtering mechanism is applied to filter spammers and bot users. As a third step, demographics information is extracted out of the valid users, namely gender, age, ethnicity and location information. Finally, the political polarity of the users with respect to the analyzed event is predicted. In the scope of this work, our proposed pipeline is applied to two referendum scenarios (independence of Catalonia in Spain and autonomy of Lombardy in Italy) in order to assess the performance of the approach with respect to the capability of collecting correct insights on the demographics of social media users and of predicting the poll results based on the opinions shared by the users. Experiments show that the method was effective in predicting the political trends for the Catalonia case, but not for the Lombardy case. Among the various motivations for this, we noticed that in general Twitter was more representative of the users opposing the referendum than the ones in favor.
