Abstract: The present invention discloses a review-aware recommendation system that leverages Fine-Grained Sentiment Analysis (FGSA) and Graph Attention Networks (GATs) to generate accurate, personalized, and context-aware recommendations. The system integrates Artificial Intelligence (AI), Machine Learning (ML), Deep Learning (DL), Natural Language Processing (NLP), and Graph Neural Networks (GNNs) to analyze user-generated reviews, ratings, purchase history, browsing behavior, and product information collected from e-commerce platforms, online marketplaces, streaming services, and social networking applications. The invention performs fine-grained sentiment analysis to identify product or service aspects and determine aspect-level sentiment polarity, thereby capturing detailed user preferences beyond conventional document-level sentiment analysis. A heterogeneous graph representing users, items, reviews, and aspect relationships is constructed and processed using a Graph Attention Network, which assigns adaptive attention weights to neighboring nodes to learn meaningful semantic and structural representations. The sentiment features and graph embeddings are integrated within a recommendation engine to predict user preferences, rank candidate items, and generate personalized recommendations in real time. The system continuously updates its recommendation model using newly generated reviews and user interactions, thereby improving adaptability and recommendation quality. By combining aspect-level opinion mining with graph attention-based representation learning, the proposed invention enhances recommendation accuracy, addresses data sparsity and cold-start challenges, improves explainability, and provides scalable, intelligent recommendation services across diverse digital platforms.
