摘要:

该研究旨在了解Twitter用户对COVID-19的话语和心理反应。我们使用机器学习技术分析了从2020年1月23日至3月7日收集的约190万条与冠状病毒相关的推文(用英语撰写)。报告共列出11个重要主题,并将其分为10个主题,包括“确诊病例的最新情况”、“与COVID-19相关的死亡”、“中国以外(全球)的病例”、“韩国COVID-19疫情”、“纽约疫情的早期迹象”、“钻石公主号邮轮”、“经济影响”、”预防措施”、“当局”和“供应链”。“结果并没有显示治疗和症状相关的信息是Twitter上的流行话题。情感分析显示,对冠状病毒未知性质的恐惧在所有话题中占主导地位。最后,本文还讨论了本研究的意义和局限性。

英文摘要:

The study aims to understand Twitter users' discourse and psychological reactions to COVID-19. We use machine learning techniques to analyze about 1.9 million Tweets (written in English) related to coronavirus collected from January 23 to March 7, 2020. A total of salient 11 topics are identified and then categorized into ten themes, including "updates about confirmed cases," "COVID-19 related death," "cases outside China (worldwide)," "COVID-19 outbreak in South Korea," "early signs of the outbreak in New York," "Diamond Princess cruise," "economic impact," "Preventive measures," "authorities," and "supply chain." Results do not reveal treatments and symptoms related messages as prevalent topics on Twitter. Sentiment analysis shows that fear for the unknown nature of the coronavirus is dominant in all topics. Implications and limitations of the study are also discussed.
