AI总结:

本研究针对现有线上自我呈现研究依赖关键词方法的局限,提出一套有理论依据的个人简介嵌入方法,在四项任务上优于基线,还用于探究自我呈现与Twitter错误信息分享的关联,为相关研究提供了新工具与新见解。

摘要:

社交媒体平台为用户提供了个人资料描述栏,通常称为“bio(个人简介)”,用户可在此向外界展示自己。越来越多的文献表明,这些简介中的文本能帮助我们更好地理解线上自我呈现与行为,但现有研究完全依赖基于关键词的方法实现这一目标。本文提出并评估了一套简单、有效且具备理论依据的方法,可将个人简介嵌入到捕捉年龄、党派倾向等社会意义显著维度的空间中。我们在四项任务上评估了所提方法,结果显示最优方法的表现优于多个实用基线。随后我们展示了该方法的效用:它可帮助理解Twitter上自我呈现与分享低质量新闻网站URL之间的关联,尤其聚焦于探究年龄与党派倾向的相互作用,以及宗教信仰自我呈现的影响。本研究为计算社会科学家利用个人简介中的信息提供了新工具,也为Twitter上错误信息分享的认知方式提供了新见解。

英文摘要:

Social media platforms provide users with a profile description field, commonly known as a ``bio," where they can present themselves to the world. A growing literature shows that text in these bios can improve our understanding of online self-presentation and behavior, but existing work relies exclusively on keyword-based approaches to do so. We here propose and evaluate a suite of \hl{simple, effective, and theoretically motivated} approaches to embed bios in spaces that capture salient dimensions of social meaning, such as age and partisanship. We \hl{evaluate our methods on four tasks, showing that the strongest one out-performs several practical baselines.} We then show the utility of our method in helping understand associations between self-presentation and the sharing of URLs from low-quality news sites on Twitter\hl{, with a particular focus on explore the interactions between age and partisanship, and exploring the effects of self-presentations of religiosity}. Our work provides new tools to help computational social scientists make use of information in bios, and provides new insights into how misinformation sharing may be perceived on Twitter.
