全球Tweet提及COVID-19的次数

Global Tweet Mentions of COVID-19

Guangqing Chi, Junjun Yin, M. Luke Smith, Yosef Bodovski

摘要:

背景COVID-19疫情持续蔓延一年半,逾400万人死亡,其相关话题继续主导全球媒体。尽管COVID-19的诊断得到了很好的监测,但这种疾病对人类行为和社会动态的影响以及旨在遏制其的政策干预措施的有效性都没有得到充分的了解。监测行为、社会动态和政策的空间和时间模式-以及它们之间的相互关系-可以为准备行动和有效应对提供关键信息。方法.在这里,我们展示了一个由192万个关键词选择的Twitter帖子组成的开源数据集,从2020年1月至今每周更新,以及一个动态仪表板,显示国家和国家以下行政区划的总数。结果仪表板显示100%带有地理标记的推文,其中包含与COVID-19相关的关键字或主题标签。我们使用基于机器学习的文本分类器验证了我们的纳入标准,发现88%的选定推文被正确标记为与COVID-19相关。有了这些信息,我们测试了2020年1月1日至2020年12月31日期间推文与新冠肺炎诊断之间的相关性,发现随着时间的推移,相关性逐渐降低。结论.随着新冠病毒变种的出现,但疫苗的犹豫和耐药性仍在持续,研究人员可以使用该数据集来研究COVID-19的许多方面,并为准备未来的大流行病提供有价值的见解。

英文摘要:

Background. After a year and half and over 4 million deaths, the COVID-19 pandemic continues to be widespread, and its related topics continue to dominate the global media. Although COVID-19 diagnoses have been well monitored, neither the impacts of the disease on human behavior and social dynamics nor the effectiveness of policy interventions aimed at its containment are fully understood. Monitoring the spatial and temporal patterns of behavior, social dynamics and policy - and then their interrelations - can provide critical information for preparatory action and effective response. Methods. Here we present an open-source dataset of 1.92 million keyword-selected Twitter posts, updated weekly from January 2020 to present, along with a dynamic dashboard showing totals at national and subnational administrative divisions. Results. The dashboard presents 100% of the geotagged tweets that contain keywords or hashtags related COVID-19. We validated our inclusion criteria using a machine learning-based text classifier and found that 88% of the selected tweets were correctly labeled as related to COVID-19. With this information we tested the correlation between tweets and covid diagnosis from January 1, 2020 through December 31, 2020 and see a decreasing correlation across time. Conclusions. With emerging COVID variants but ongoing vaccine hesitancy and resistance, this dataset could be used by researchers to study numerous aspects of COVID-19 and provide valuable insights for preparing future pandemics.
