Abstract

This study presents a Bidirectional Long Short-Term Memory (**Bi-LSTM**) deep learning model for **emotion recognition from text**. Designed to classify six core emotions—**Sadness, Anger, Love, Surprise, Fear, Joy**—the model utilizes forward and backward LSTMs to capture full contextual dependencies within sentence structure. Results show superior performance over baseline algorithms on key metrics including **accuracy, precision, recall**, and **F1-score**, offering practical use cases for mental health monitoring, social media analysis, and human-computer interaction.

Keywords

Deep Learning, LSTM, Bi-LSTM, Text, Emotion Recognition

Conclusion

The BiLSTM architecture proves effective for emotion classification in natural language text, outperforming traditional models by leveraging **bidirectional context** and sequential memory. Future work may integrate **attention mechanisms**, **transfer learning**, and larger corpora to improve precision and interpretability. This research contributes to the growing domain of emotion-aware intelligent systems.
