Linguistic style matching (LSM) in conversations can be reflective of several aspects of social influence such as power or persuasion. However, how LSM relates to the outcomes of online communication on platforms such as Reddit is an unknown question. In this study, we analyze a large corpus of two-party conversation threads in Reddit where we identify all occurrences of LSM using two types of style: the use of function words and formality. Using this framework, we examine how levels of LSM differ in conversations depending on several social factors within Reddit: post and subreddit features, conversation depth, user tenure, and the controversiality of a comment. Finally, we measure the change of LSM following loss of status after community banning. Our findings reveal the interplay of LSM in Reddit conversations with several community metrics, suggesting the importance of understanding conversation engagement when understanding community dynamics.

翻译：对话中的语言风格匹配可反映社会影响力的多个方面，如权力或说服力。然而，语言风格匹配如何与Reddit等平台上在线沟通的结果相关联，仍是一个未知问题。本研究通过分析Reddit中大量双人对话线程，利用两类语言风格——功能词使用和正式程度——识别所有语言风格匹配现象。基于此框架，我们考察了对话中语言风格匹配水平如何因Reddit内多种社会因素而异：帖子与子版块特征、对话深度、用户资历及评论的争议性。最后，我们测量了社区封禁导致地位丧失后语言风格匹配的变化。研究结果揭示了Reddit对话中语言风格匹配与多种社区指标的相互作用，表明理解对话参与度对把握社区动态具有重要意义。
