从Reddit上COVID-19个人经历的叙述中提取症状（CS CL）---刘子蔚

社会媒体对COVID-19的讨论为该病毒如何影响人们的生活提供了丰富的信息来源，这在质量上与传统的公共卫生数据集有所不同。特别是，当个人在社交媒体上自我报告病毒传播过程中的经历时，它可以识别出患者出现症状的每个阶段的情绪。在Reddit论坛r / COVID19Positive上的帖子包含来自COVID-19阳性患者的第一手资料，深入了解了与病毒的个人斗争。这些帖子通常具有时态结构，指示出现文字所指症状后的天数。使用主题建模和情感分析，我们量化了自症状发作以来的前14天中，COVID-19讨论在个人整个经历中的变化。有关发烧，咳嗽和喉咙痛等早期症状的讨论主要集中在帖子开始时，而表示呼吸问题的语言则在十天左右达到顶峰。还确定了一些围绕关键案例的对话，并以大致恒定的速度出现。我们确定了与这些症状的演变相关的两个清晰的正面和负面情绪群，并绘制了它们之间的关系。我们的结果为COVID-19的患者体验提供了一个视角，可补充其他医学数据流，并可能揭示何时可能出现精神健康问题。还确定了一些围绕关键案例的对话，并以大致恒定的速度出现。我们确定了与这些症状的演变相关的两个清晰的正面和负面情绪群，并绘制了它们之间的关系。我们的结果为COVID-19的患者体验提供了一个视角，可补充其他医学数据流，并可能揭示何时可能出现精神健康问题。还确定了一些围绕关键案例的对话，并以大致恒定的速度出现。我们确定了与这些症状的演变相关的两个清晰的正面和负面情绪群，并绘制了它们之间的关系。我们的结果为COVID-19的患者体验提供了一个视角，可补充其他医学数据流，并可能揭示何时可能出现精神健康问题。

原文标题：Symptom extraction from the narratives of personal experiences with COVID-19 on Reddit

原文：Social media discussion of COVID-19 provides a rich source of information into how the virus affects people's lives that is qualitatively different from traditional public health datasets. In particular, when individuals self-report their experiences over the course of the virus on social media, it can allow for identification of the emotions each stage of symptoms engenders in the patient. Posts to the Reddit forum r/COVID19Positive contain first-hand accounts from COVID-19 positive patients, giving insight into personal struggles with the virus. These posts often feature a temporal structure indicating the number of days after developing symptoms the text refers to. Using topic modelling and sentiment analysis, we quantify the change in discussion of COVID-19 throughout individuals' experiences for the first 14 days since symptom onset. Discourse on early symptoms such as fever, cough, and sore throat was concentrated towards the beginning of the posts, while language indicating breathing issues peaked around ten days. Some conversation around critical cases was also identified and appeared at a roughly constant rate. We identified two clear clusters of positive and negative emotions associated with the evolution of these symptoms and mapped their relationships. Our results provide a perspective on the patient experience of COVID-19 that complements other medical data streams and can potentially reveal when mental health issues might appear.
