This study investigates whether division on political topics is mapped with the distinctive patterns of language use. We collect a total 145,832 Reddit comments on the abortion debate and explore the languages of subreddit communities r/prolife and r/prochoice. With consideration of the Moral Foundations Theory, we examine lexical patterns in three ways. First, we compute proportional frequencies of lexical items from the Moral Foundations Dictionary in order to make inferences about each group's moral considerations when forming arguments for and against abortion. We then create n-gram models to reveal frequent collocations from each stance group and better understand how commonly used words are patterned in their linguistic context and in relation to morality values. Finally, we use Latent Dirichlet Allocation to identify underlying topical structures in the corpus data. Results show that the use of morality words is mapped with the stances on abortion.

研究考察了政治话题上的分歧是否与语言使用的独特模式有关，收集了 Reddit 上关于堕胎辩论的总共145,832条评论，分析了 r/prolife 和 r/prochoice 的子版块社群中的语言使用。通过考虑道德基础理论，分析了三种词汇模式，包括计算道德基础词典中词汇项目的比例频率，创建 n-gram 模型以揭示各立场群体常用的词汇搭配，以及使用潜在狄利克雷分配来识别语料库数据中的主题结构。研究结果表明，道德词汇的使用与对堕胎的立场相关联。
