Abstract

The invention provides a text sentiment analysis method, comprising: inputting the general semantic matrix, the structural semantic matrix, and the sentence initialization representation into the graph convolutional neural network, the cross network and the activation function, and obtaining the general semantic syntactic representation and the structural semantic syntactic representation of the sentence , and then combine the general semantic hidden representation and the structural semantic hidden representation of the sentence to calculate the target structure semantic syntax representation and the target general semantic syntax representation, splicing the target general semantic syntax representation and the target structure semantic syntax representation and masking non-attribute words, Get the attribute word feature representation of each word in the sentence, and then calculate the attention weight of each word in the sentence according to the word embedding representation and each attribute word feature representation, and output the sentence emotional pole based on the word embedding representation and the attention weight of each word sex. The text sentiment analysis method of the present invention can efficiently and accurately analyze the sentiment polarity of sentences in the text.

Description

technical field [0001] The invention relates to the technical field of text analysis, in particular to a text sentiment analysis method. Background technique [0002] Fine-grained sentiment analysis (ABSA) is an important task in natural language processing. For a given (sentence, attribute word) pair, it aims to judge the attribute word based on the context information related to the specific attribute word in the sentence. emotional polarity (eg, positive, neutral, negative). With the continuous development of the Internet and big data, sentiment analysis technology, which can automatically extract useful information from a large amount of text, has not only attracted the attention of many academic circles, but also is widely used in daily business activities, especially in social media. , e-commerce and social public opinion analysis and other fields. [0003] In the existing fine-grained sentiment analysis process, the main goal is to accurately find sentiment words th...
