  • Abstract:
  • Customer review sentiment classification is a major application of Natural Language Processing used to identify customer opinions, emotions, and satisfaction levels from textual feedback. Modern businesses receive large numbers of reviews through e-commerce websites, food delivery applications, hotel booking portals, and social media platforms. Manual analysis of such large review datasets is difficult, slow, and inconsistent. This project develops a Python-based machine learning system to automatically classify customer reviews into positive, negative, and neutral sentiments. Text preprocessing methods such as tokenization, stop-word removal, punctuation removal, lowercasing, stemming, lemmatization, and TF-IDF vectorization are applied to improve prediction accuracy. The Multinomial Naive Bayes algorithm is used for classification because it is simple, fast, memory-efficient, and highly effective for text classification tasks. The system improves customer satisfaction analysis, service quality, and business decision-making.
