AI总结:

本研究分析2020年1月至2022年10月澳大利亚COVID-19相关Twitter讨论,运用监督与无监督前沿方法开展多维度分析,探索讨论动态以助力疫情管理自动化信息系统开发。

摘要:

社交媒体平台蕴含海量数据,可为历史事件与实时事件的研究提供全面认知。危机事件发生期间,社交媒体的使用量会达到峰值,人们会在平台上讨论自身的所见、所闻与所感。已有研究证实,这类公众生成的讨论内容能帮助公众、一线应急响应人员和决策者更深入地了解事件在基层的实际发展情况。本研究对2020年1月至2022年10月期间澳大利亚境内产生的COVID-19相关Twitter讨论内容开展了全面分析。我们采用监督与无监督领域的前沿方法,对澳大利亚Twitter生态进行了网络分析、主题建模、情感分析与因果分析。鉴于研究结果可全面呈现COVID-19疫情期间澳大利亚Twitter平台的讨论生态,本研究旨在探索讨论动态,为未来流行病/疫情管理自动化信息系统的开发提供支持。

英文摘要:

Social media platforms contain abundant data that can provide comprehensive knowledge of historical and real-time events. During crisis events, the use of social media peaks, as people discuss what they have seen, heard, or felt. Previous studies confirm the usefulness of such socially generated discussions for the public, first responders, and decision-makers to gain a better understanding of events as they unfold at the ground level. This study performs an extensive analysis of COVID-19-related Twitter discussions generated in Australia between January 2020, and October 2022. We explore the Australian Twitterverse by employing state-of-the-art approaches from both supervised and unsupervised domains to perform network analysis, topic modeling, sentiment analysis, and causality analysis. As the presented results provide a comprehensive understanding of the Australian Twitterverse during the COVID-19 pandemic, this study aims to explore the discussion dynamics to aid the development of future automated information systems for epidemic/pandemic management.
