The COVID-19 pandemic has had adverse effects on both physical and mental health. During this pandemic, numerous studies have focused on gaining insights into health-related perspectives from social media. In this study, our primary objective is to develop a machine learning-based web application for automatically classifying COVID-19-related discussions on social media. To achieve this, we label COVID-19-related Twitter data, provide benchmark classification results, and develop a web application. We collected data using the Twitter API and labeled a total of 6,667 tweets into five different classes: health risks, prevention, symptoms, transmission, and treatment. We extracted features using various feature extraction methods and applied them to seven different traditional machine learning algorithms, including Decision Tree, Random Forest, Stochastic Gradient Descent, Adaboost, K-Nearest Neighbour, Logistic Regression, and Linear SVC. Additionally, we used four deep learning algorithms: LSTM, CNN, RNN, and BERT, for classification. Overall, we achieved a maximum F1 score of 90.43% with the CNN algorithm in deep learning. The Linear SVC algorithm exhibited the highest F1 score at 86.13%, surpassing other traditional machine learning approaches. Our study not only contributes to the field of health-related data analysis but also provides a valuable resource in the form of a web-based tool for efficient data classification, which can aid in addressing public health challenges and increasing awareness during pandemics. We made the dataset and application publicly available, which can be downloaded from this link https://github.com/Bishal16/COVID19-Health-Related-Data-Classification-Website.

对疫苗接种的态度变得更加两极分化;在网上看到疫苗虚假信息和边缘阴谋论是很常见的。Ojea Quintana et al.（2021）对Twitter疫苗话语进行了观察性研究：作者分析了大约六个月的Twitter话语-2019年12月至2020年6月期间的130万条原始推文和1800万条转发，范围从新冠肺炎大流行之前到之后。这项工作扩展了Ojea Quintana et al.（2021）的数据科学的两个主要贡献。首先，基于作者最初的网络聚类和定性分析技术，我们能够清楚地划分和可视化话语中使用的语言模式，由反疫苗接种运动者（反疫苗接种运动者和疫苗否认者）与其他集群（统称，其他人）。其次，利用Antivaxxers的推文的特点，我们开发了文本分类器来确定给定用户使用反疫苗接种语言的可能性，最终有助于建立一个早期预警机制，以改善我们的认知环境的健康状况，并支持（而不是阻碍）公共卫生举措。
