论文摘要
由于全球访问互联网以及移动技术的持续进展，物理和数字世界已经完全融合在一起，社交媒体平台的扩散在这一演变中发挥了领导作用。在本文中，我们进行了彻底的分析，以更好地想象和理解表征和区分受精神障碍影响的社交媒体使用者的因素。我们进行了不同的实验，研究语言的多个维度，包括词汇唯一性，单词用法，语言样式，心理测量属性，情感的共处模式以及在线行为特征，包括社交参与和发布趋势。我们的发现揭示了功能单词的使用存在显着差异，例如副词和动词时态以及特定于主题的词汇，例如生物过程。至于情感表达，我们观察到，受影响的用户平均比对照个体更规律地分享情绪。总体而言，受影响组的每月发布差异高于对照组。此外，我们发现了证据表明，与其他限制性较小的平台相比，精神障碍用户对微博平台上的语言使用不太区分。特别是，与REDDIT相比，我们在Twitter上观察到的受影响组和对照组之间的可量化差异较少。
Due to the worldwide accessibility to the Internet along with the continuous advances in mobile technologies, physical and digital worlds have become completely blended, and the proliferation of social media platforms has taken a leading role over this evolution. In this paper, we undertake a thorough analysis towards better visualising and understanding the factors that characterise and differentiate social media users affected by mental disorders. We perform different experiments studying multiple dimensions of language, including vocabulary uniqueness, word usage, linguistic style, psychometric attributes, emotions' co-occurrence patterns, and online behavioural traits, including social engagement and posting trends. Our findings reveal significant differences on the use of function words, such as adverbs and verb tense, and topic-specific vocabulary, such as biological processes. As for emotional expression, we observe that affected users tend to share emotions more regularly than control individuals on average. Overall, the monthly posting variance of the affected groups is higher than the control groups. Moreover, we found evidence suggesting that language use on micro-blogging platforms is less distinguishable for users who have a mental disorder than other less restrictive platforms. In particular, we observe on Twitter less quantifiable differences between affected and control groups compared to Reddit.
