Abstract

The invention relates to a fine-grained sentiment analysis method and system, computer equipment and a storage medium, and the fine-grained sentiment analysis method comprises the following steps: a vector acquisition step: inputting input text data into a shared network structure layer, in the shared network structure layer, acquiring a word vector, a word vector and a position vector according to the text data, obtaining a vector representation of the text data, and obtaining a feature extraction vector and an emotion vector according to the vector representation; an emotion probability vector acquisition step: inputting the feature extraction vector and the emotion vector into a non-shared network structure layer, and outputting an emotion probability vector of a corresponding aspect; and an emotion label obtaining step of obtaining a final emotion label according to the emotion probability vector. According to semantic information obtained by a Bert model based on a self-attention mechanism and text features of sentence levels obtained by performing feature extraction on a whole text sequence, the recognition capability of a network structure on an aspect emotion direction is enhanced.

Description

technical field [0001] The present application relates to the technical field of text sentiment analysis in natural language processing, in particular to fine-grained sentiment analysis methods, systems, computer equipment and storage media. Background technique [0002] At present, text comments on the Internet (including social comments, news comments, commodity reviews, etc.) have academic and commercial value, and sentiment analysis can be performed on comments or comments to identify the corresponding user's opinion, sentiment, and attitude towards an event or product. For example, social platforms and news portals can use the information after sentiment analysis to provide targeted marketing and push to users; e-commerce platforms can use sentiment analysis technology to analyze the attributes of various aspects of products to obtain the evaluation of consumers. It not only saves the browsing time of other consumers, but also displays refined labels for product evaluat...
