Classifying COVID-19 Related Tweets for Fake News Detection and Sentiment Analysis with BERT-based Models

Abstract: The present paper is about the participation of our team "techno" on CERIST'22 shared tasks. We used an available dataset "task1.c" related to covid-19 pandemic. It comprises 4128 tweets for sentiment analysis task and 8661 tweets for fake news detection task. We used natural language processing tools with the combination of the most renowned pre-trained LLMs BERT (Bidirectional Encoder Representations from Transformers). The results shows the efficacy of pre-trained LLMs as we attained an accuracy of 0.93 for the sentiment analysis task and 0.90 for the fake news detection task.
