Comments with responses.

In May 2023, the United States surgeon general put out an advisory suggesting that loneliness and social isolation should be tackled and prioritized like health conditions such as substance abuse. Online loneliness forums provide a platform for users experiencing loneliness to engage with, share experiences/concerns, and seek support from others. On these forums, users (posters) publish support seeking posts and other users respond by either reacting to these posts and/or writing comments in which they provide support. In some cases, the posters respond to and engage with the comments that their posts elicit; understanding these interactions between posters and the comments their posts elicit can inform helpful communication strategies on online loneliness forums and online health forums, in general. Prior work on analyzing data from online loneliness forums did not study the interactions between posters and the comments their posts elicit. To address this, we present a dataset of posts and comments published in a 4 year time period i.e. from January 1 2019 to December 31 2022 on an online loneliness forum on Reddit. This dataset consists of (a) posts, (b) all the comments associated with these posts, (c) the comments that elicited responses from the posters, and (d) the responses of the posters to these comments. With this dataset, we conduct analysis using a topic modeling algorithm called BERTopic and a psycholinguistic dictionary called Linguistic Inquiry and word count (LIWC) to gain insights and elucidate the language markers associated with comments (to posts) that elicit responses from the posters. We find that as it relates to comments that received responses from posters, the following topic themes were associated with these comments i.e. relationships, empathy, and mental health concerns and the LIWC categories on second person pronoun, social processes, and present focus, were associated with these comments. We also find that the topic themes on appreciation was associated with the responses by posters to comments their posts received. We discuss these findings in the discussion section.2023年5月，美国卫生局局长（United States Surgeon General）发布一则健康指导公告（advisory），提出应如同对待物质滥用等健康问题一般，将孤独感与社会孤立问题纳入优先应对范畴。在线孤独论坛为存在孤独困扰的用户搭建了交流平台，供其分享经历与顾虑、寻求他人支持。在这类论坛中，用户（发帖者）发布求助类帖子，其他用户则通过对帖子作出反应或撰写评论的方式提供支持。部分场景下，发帖者会对其帖子引发的评论进行回应并互动。理解发帖者与其帖子所引发评论间的这类互动，可为在线孤独论坛乃至一般性在线健康论坛的有效沟通策略提供参考依据。既往针对在线孤独论坛数据的分析研究，并未探讨发帖者与其帖子所引发评论间的互动关系。为填补这一研究空白，我们发布了一份数据集，涵盖2019年1月1日至2022年12月31日这四年间，Reddit平台上某在线孤独论坛的帖子与评论数据。该数据集包含四部分内容：(a) 全部发帖内容；(b) 与这些帖子关联的所有评论；(c) 引发发帖者回应的评论；(d) 发帖者针对这些评论作出的回应。依托该数据集，我们采用主题建模算法BERTopic与心理语言学词典《语言探究与词频统计》（Linguistic Inquiry and Word Count, LIWC）开展分析，以获取相关研究洞察，并阐明能引发发帖者回应的（针对帖子的）评论所蕴含的语言标记。研究结果显示，针对获得发帖者回应的评论，其关联主题包括人际关系、共情与心理健康困扰；LIWC分类维度中的第二人称代词、社会互动过程与当下聚焦表述，也与这类评论存在显著关联。此外，我们发现发帖者针对所获评论作出的回应，其主题与"感谢"相关。我们将在讨论章节中对上述研究发现展开详细阐述。
