Text sentiment analysis based on two-channel joint model

Published: 06 March 2023 Publication History

Abstract

Convolutional neural networks (CNNs) have a strong feature learning capability. Bi-directional long and short-term memory network (BiLSTM) avoids the problem of gradient disappearance in traditional neural networks and is able to learn contextually relevant features better. The attention mechanism plays the role of feature weight distribution, which can better acquire important features. In this paper, we propose a two-channel joint model for sentiment analysis based on IMDB review texts. And a series of comparison experiments are conducted on the dataset, and the accuracy and RMSE values of the method reach 91.52% and 0.2636, respectively. the results show that the proposed model can effectively improve the accuracy of text classification.
