摘要:

2020年,COVID-19成为全球关注的焦点,并仍广泛反映在所有社交网络中。每天,用户发布数百万条关于这个主题的推文和评论,其中包含有关公众舆论的重要隐含信息。在这方面,我们收集了一个英文的新冠病毒相关推文数据集,该数据集由2020年3月23日至6月23日的200多万条推文组成,以提取各国人民在疫情爆发初期的感受。为此,首先,我们使用基于词典的方法结合GeoNames地理数据库来标记tweet的位置。接下来,提出了一种基于最近引入并被广泛引用的RoBERTa模型的方法来分析它们的情感内容。之后,为全球和更多参与COVID-19的国家制作推文频率和情绪的趋势图。图形分析表明,大多数国家的推文频率图与官方统计的每日患病人数显着相关。此外,几个隐含的知识提取和讨论。

英文摘要:

In 2020, COVID-19 became the chief concern of the world and is still reflected widely in all social networks. Each day, users post millions of tweets and comments on this subject, which contain significant implicit information about the public opinion. In this regard, a dataset of COVID-related tweets in English language is collected, which consists of more than two million tweets from March 23 to June 23 of 2020 to extract the feelings of the people in various countries in the early stages of this outbreak. To this end, first, we use a lexicon-based approach in conjunction with the GeoNames geographic database to label the tweets with their locations. Next, a method based on the recently introduced and widely cited RoBERTa model is proposed to analyze their sentimental content. After that, the trend graphs of the frequency of tweets as well as sentiments are produced for the world and the nations that were more engaged with COVID-19. Graph analysis shows that the frequency graphs of the tweets for the majority of nations are significantly correlated with the official statistics of the daily afflicted in them. Moreover, several implicit knowledge is extracted and discussed.
