Hybrid HAN-CNN with aspect term extraction for sentiment analysis using product review
In this article, an intensive sentiment analysis approach termed Hierarchical attention-convolutional neural network (HAN-CNN) has been proposed using product reviews. Firstly, the input product review is subjected to Bidirectional Encoder Representation from Transformers (BERT) tokenization, where the input data of each sentence are partitioned into little bits of words. Thereafter, Aspect Term Extraction (ATE) is carried out and feature extraction is completed utilizing some features. Finally, sentiment analysis is accomplished by the developed HAN-CNN, which is formed by combining a Hierarchical Attention Network (HAN) and a Convolutional Neural Network (CNN). Moreover, the proposed HAN-CNN achieved a greater performance with maximum accuracy, recall and F1-Score of 91.70%, 90.60% and 91.20%, respectively.
