Hybrid Bi-LSTM Framework for Aspect-Based Sentiment Analysis in E-Commerce Reviews

Aspect-Based Sentiment Classification (ABSC) is the core technology for e-commerce websites, offering business entities in-depth customer preference information through online review sentiment extraction. In this paper, a Hybrid Bi-LSTM Framework is proposed to integrate weak supervision with deep learning models to increase the accuracy of sentiment classification. The approach is based on aspect term extraction, weak labeling with Snorkel-based methods, and a multi-model sentiment analysis method known as HABSC (Hybrid Aspect-Based Sentiment Classification). It uses Amazon product review datasets to evaluate the performance difference between a Hybrid Bi-LSTM model, the HABSC algorithm, and an ABSC DeBERT model in sentiment classification for five important aspects: price, quality, usability, size, and service. Experimental results indicate that Hybrid Bi-LSTM performs better than ABSC DeBERT, achieving 93.4% accuracy, lower Hamming loss, and improved precision, recall, and F1-score. Comparative analysis also reflects the performance of an ensemble-based sentiment analysis approach employing VADER, SentiWordNet, and BERT scoring. This article contributes to enhanced automated aspect-based sentiment analysis, presenting an efficient and scalable solution for recommendation systems, business intelligence, and e-commerce websites.
