In recent years, the ease with which social media can be accessed has led to the unexpected problem of a shrinkage in information sources. This phenomenon is caused by a system that facilitates the connection of people with similar ideas and recommendation systems. Bias in the selection of information sources promotes polarization that divides people into multiple groups with opposing views and creates conflicts between opposing groups. This paper elucidates the mechanism of polarization by proposing a model of opinion formation in social media that considers users' reactions of empathy and repulsion. Based on the idea that opinion neutrality is only relative, this model offers a novel technology for dealing with polarization.

由移情和排斥引起的社交媒体极化模型

近年来，社交媒体的便捷访问导致了意想不到的信息来源萎缩问题。这种现象是由一个有助于将具有相似想法的人联系起来的系统和推荐系统引起的。信息来源选择的偏见助长了两极分化，将人们分成多个持有相反观点的群体，并在对立的群体之间制造冲突。本文通过提出一个考虑用户对同理心和排斥反应的社交媒体意见形成模型来阐明两极分化的机制。基于意见中立只是相对的思想，该模型提供了一种处理两极分化的新技术。
