CIA_NITT at WNUT-2020 Task 2: Classification of COVID-19 Tweets Using Pre-trained Language Models

This paper presents our models for WNUT 2020 shared task2. The shared task2\ninvolves identification of COVID-19 related informative tweets. We treat this\nas binary text classification problem and experiment with pre-trained language\nmodels. Our first model which is based on CT-BERT achieves F1-score of 88.7%\nand second model which is an ensemble of CT-BERT, RoBERTa and SVM achieves\nF1-score of 88.52%.\n
