摘要:

了解公众对COVID-19疫苗的反应是控制COVID-19疫情的关键成功因素。为了了解公众的反应,有必要探讨民意。传统的调查费用昂贵,耗时,涉及的健康问题有限,获得的数据规模较小。Twitter可以提供一个很好的机会来了解公众对COVID-19疫苗的看法。目前的研究提出了一种使用计算和人类编码方法来收集和分析大量推文的方法,以提供关于COVID-19疫苗的更广泛的视角。本研究使用机器学习基于规则的方法来识别推文的情感,发现主要主题,探索时间趋势,并使用统计测试来比较负面和非负面推文的主题,并揭示具有负面和非负面情感的推文的热门主题。我们的研究结果显示,2020年11月至2021年2月期间,有关COVID-19疫苗的负面情绪呈下降趋势。我们发现Twitter用户在2020年11月至2021年2月期间讨论了从疫苗接种地点到2020年美国大选的广泛话题。研究结果表明,有一个显着的差异之间的推文有负面和非负面情绪的权重的大多数主题。我们的研究结果还表明,负面和非负面的推文有不同的主题优先级和重点。这项研究表明,Twitter数据可用于探索有关COVID-19疫苗的公众意见。

英文摘要:

The understanding of the public response to COVID-19 vaccines is the key success factor to control the COVID-19 pandemic. To understand the public response, there is a need to explore public opinion. Traditional surveys are expensive and time-consuming, address limited health topics, and obtain small-scale data. Twitter can provide a great opportunity to understand public opinion regarding COVID-19 vaccines. The current study proposes an approach using computational and human coding methods to collect and analyze a large number of tweets to provide a wider perspective on the COVID-19 vaccine. This study identifies the sentiment of tweets using a machine learning rule-based approach, discovers major topics, explores temporal trend and compares topics of negative and non-negative tweets using statistical tests, and discloses top topics of tweets having negative and non-negative sentiment. Our findings show that the negative sentiment regarding the COVID-19 vaccine had a decreasing trend between November 2020 and February 2021. We found Twitter users have discussed a wide range of topics from vaccination sites to the 2020 U.S. election between November 2020 and February 2021. The findings show that there was a significant difference between tweets having negative and non-negative sentiment regarding the weight of most topics. Our results also indicate that the negative and non-negative tweets had different topic priorities and focuses. This research illustrates that Twitter data can be used to explore public opinion regarding the COVID-19 vaccine.
