Because language is subjective, it can be difficult to infer human emotions from textual data. This work investigates the categorization of emotions using BERT, classifying five emotions—angry, fearful, joyful, sad, and surprised—by utilizing its contextual embeddings. Preprocessing techniques like tokenization and stop-word removal are used on the dataset, which comes from social media and personal tales. With a weighted F1-score of 0.75, our model was trained using a multi-label classification strategy. BERT has the lowest F1-score when it comes to rage, but it does well when it comes to identifying fear and surprise. The findings demonstrate the difficulties presented by unbalanced datasets while also highlighting the promise of transformer-based models for text-based emotion identification. Future research will use data augmentation methods, domain-adapted BERT models, and other methods to improve classification performance.
