摘要:

随着冠状病毒大流行,另一场危机以大规模恐惧和恐慌现象的形式表现出来,这是由不完整且往往不准确的信息所推动的。因此,非常需要解决和更好地了解COVID-19的信息危机,并衡量公众情绪,以便实施适当的信息传递和政策决策。在这篇研究文章中,我们使用冠状病毒特定的推文和R统计软件及其情感分析包来识别与大流行相关的公众情绪。我们通过必要的文本数据可视化支持的描述性文本分析,展示了随着COVID-19在美国接近峰值水平,恐惧情绪随时间推移的进展。此外,我们在文本分析的背景下提供了两种基本的机器学习(ML)分类方法的方法学概述,并比较了它们对不同长度的冠状病毒推文进行分类的有效性。我们观察到一个强大的分类准确率为91%的短推文,与朴素贝叶斯方法。我们还观察到,逻辑回归分类方法对较短的推文提供了74%的合理准确度,而这两种方法对较长的推文表现出相对较弱的性能。这项研究提供了对冠状病毒恐惧情绪进展的见解,并概述了相关的方法,影响,限制和机会。

英文摘要:

Along with the Coronavirus pandemic, another crisis has manifested itself in the form of mass fear and panic phenomena, fueled by incomplete and often inaccurate information. There is therefore a tremendous need to address and better understand COVID-19's informational crisis and gauge public sentiment, so that appropriate messaging and policy decisions can be implemented. In this research article, we identify public sentiment associated with the pandemic using Coronavirus specific Tweets and R statistical software, along with its sentiment analysis packages. We demonstrate insights into the progress of fear-sentiment over time as COVID-19 approached peak levels in the United States, using descriptive textual analytics supported by necessary textual data visualizations. Furthermore, we provide a methodological overview of two essential machine learning (ML) classification methods, in the context of textual analytics, and compare their effectiveness in classifying Coronavirus Tweets of varying lengths. We observe a strong classification accuracy of 91% for short Tweets, with the Naive Bayes method. We also observe that the logistic regression classification method provides a reasonable accuracy of 74% with shorter Tweets, and both methods showed relatively weaker performance for longer Tweets. This research provides insights into Coronavirus fear sentiment progression, and outlines associated methods, implications, limitations and opportunities.
