A Target-Specific Sentiment Analysis Method Based on Multi-Channel Model

Abstract

The invention discloses a specific target emotion analysis method based on a multi-channel model. According to the specific target emotion analysis method, target words and contexts are fully utilized, the method is provided with three channels, and expression of the target words and the contexts is obtained through a hierarchical pooling mechanism, an interaction attention mechanism and an attention mechanism based on the Euclidean distance. Through the three channels, the target words and the context can learn the expression helpful for sentiment classification; the technical scheme is as follows: (1) inputting a SemEval2014 data set, preprocessing the data set and dividing the data set into a training set and a test set; (2) inputting the preprocessed data into three channels respectively, and performing feature extraction to obtain vectors r1, r2, r3, r4 and r5; (3) obtaining a classification result through learning of an attention mechanism by utilizing vectors r1, r2, r3, r4 andr5; (4) carrying out sentiment classification on a specific target of each comment text in the test set by using the trained model, and comparing the sentiment classification with a label of the testset to calculate the classification accuracy; the invention belongs to the fields of natural language processing technology and sentiment calculation.
