Comparative Performance of Deep Learning Approaches for Sentiment Analysis on Pakistani Dramas and Movies Reviews

Sentiment analysis plays an important role in natural language processing, helping to understand public opinions shared through text. This study focuses on the challenge of analyzing sentiments in reviews of Pakistani dramas and movies, where mixed languages, informal expressions, and noisy data make accurate classification difficult. To solve this problem, several deep learning models were used and tested, including Long Short-Term Memory (LSTM), Gated Recurrent Unit (GRU), Bidirectional LSTM (Bi-LSTM), Recurrent Neural Network (RNN), and Convolutional Neural Network (CNN). A detailed dataset of 12,000 user reviews was collected from platforms like IMDb and YouTube. The data was cleaned and prepared through steps such as tokenization, removing unnecessary columns, normalizing, and using sentiment scoring and word embedding for feature extraction. These models were trained and tested, with their performance evaluated using accuracy, precision, recall, and F1-score. Among all, the CNN model performed the best, achieving 98.71% accuracy and a 98.49% F1-score. The Bi-LSTM model was close behind, with 98.59% accuracy and a 98.47% F1-score. In the future, the research will explore the use of advanced transformer-based models like BERT and GPT for multilingual sentiment analysis. It will also aim to build real-time sentiment classification systems. Moreover, creating sentiment lexicons for regional languages and using hybrid deep learning methods are suggested to further improve accuracy and generalization
