利用BERT模型检测针对COVID-19疫苗的反疫苗推文的增加的时间间隔

Detection of Increased Time Intervals of Anti-Vaccine Tweets for COVID-19 Vaccine with BERT Model

摘要:

对抗COVID-19最有效的解决方案是开发各种疫苗。对疫苗的不信任会阻碍这种疗法的快速有效使用。表达社会思想的手段之一是社交媒体。确定社交媒体上反疫苗接种增加的时间间隔可以帮助机构确定用于打击反疫苗接种的策略。记录和跟踪每一条人工输入的推文将是低效的,因此需要各种自动化解决方案。在本研究中,使用了双向编码器表示Transformers(BERT)模型,这是一种基于深度学习的自然语言处理(NLP)模型。在一个1506条推文的数据集中,分为四个不同的类别:新闻,无关,反疫苗和疫苗支持者,该模型以5e-6的学习率训练了25个时期。为了确定反疫苗推文集中的时间间隔,通过使用训练模型确定了652840条推文所属的类别。可视化所确定类别随时间的变化,并确定可能导致变化的事件。作为模型训练的结果,在测试数据集中,f-得分为0.81,不同类别的AUC值分别为0.99,0.91,0.92,0.92。在这个模型中,与文献中的研究不同,设计了一个辅助系统,通过测量和可视化一段时间内反疫苗推文的频率,提供机构在确定其策略时可以使用的数据,不同于检测和审查此类推文。

英文摘要:

The most effective of the solutions against Covid-19 is the various vaccines developed. Distrust of vaccines can hinder the rapid and effective use of this remedy. One of the means of expressing the thoughts of society is social media. Determining the time intervals during which anti-vaccination increases in social media can help institutions determine the strategy to be used in combating anti-vaccination. Recording and tracking every tweet entered with human labor would be inefficient, so various automation solutions are needed. In this study, The Bidirectional Encoder Representations from Transformers (BERT) model, which is a deep learning-based natural language processing (NLP) model, was used. In a dataset of 1506 tweets divided into four different categories as news, irrelevant, anti-vaccine, and vaccine supporters, the model was trained with a learning rate of 5e-6 for 25 epochs. To determine the intervals in which anti-vaccine tweets are concentrated, the categories to which 652840 tweets belong were determined by using the trained model. The change of the determined categories overtime was visualized and the events that could cause the change were determined. As a result of model training, in the test dataset, the f-score of 0.81 and AUC values for different classes were obtained as 0.99,0.91, 0.92, 0.92, respectively. In this model, unlike the studies in the literature, an auxiliary system is designed that provides data that institutions can use when determining their strategy by measuring and visualizing the frequency of anti-vaccine tweets in a time interval, different from detecting and censoring such tweets.
