Embodiment Construction

[0048] The present invention will be further described below in conjunction with accompanying drawing and embodiment.

[0049] Such as Figure 1-3 As shown, a sentiment analysis method based on the fusion of rules and neural networks, specifically includes the following steps:

[0050] Step 1. Obtain a certain number of structured comments about the target object to form the corpus to be analyzed. According to the sentiment dictionary provided by the authoritative organization, combined with the corpus, the sentiment dictionary is obtained through semantic analysis and generalization. The sentiment dictionary includes sentiment limit, sentiment degree and modifier dictionary ,Such as figure 2 shown;

[0051] Step 2. Preprocess the emotional word matching and emotional word relationship, perform word segmentation, text analysis, match the emotional words in the ontology database and comment sentences on the corpus, and mark the emotional information of the emotional words and...

Abstract

The invention discloses an emotion analysis method based on rule and neural network fusion. The method comprises the steps that 1, a certain quantity of structured comments about a target object are acquired to form a to-be-analyzed corpus, and an emotion ontology base is obtained through semantic analysis generalization according to an emotion ontology base provided by an authority in combinationwith the corpus, wherein the emotion ontology base contains emotion limits and emotion degrees; 2, emotion word matching and an emotion word relation are preprocessed, word segmentation, text analysis and ontology base matching are performed on the corpus, emotion words in sentences are commented, and emotion information of the emotion words and an depending relation corresponding to a context are annotated, wherein the emotion information contains emotion strength of the words, emotion polarity and part-of-speeches of the emotion words; and 3, emotion calculation, feature fusion and emotiontendency judgment are performed. Through the method, emotion classification can be performed according to the context more precisely.

Description

technical field [0001] The invention belongs to the field of natural language processing, in particular to a Chinese text sentiment analysis method, and provides a rule-based and neural network fusion sentiment analysis method. Background technique [0002] With the rapid development of Internet technology, a large number of information published by users about people, events, etc. , products and other target entity review information. Different from objective texts, these highly subjective commentary information contains public opinions on the above-mentioned target entities, and has very important reference value for potential users, businesses, and government departments. However, it is obviously costly, inefficient and difficult to collect and analyze these massive amounts of information manually. Text sentiment analysis technology, which uses computers to classify and extract unstructured text comments, emerges at the historic moment. [0003] At present, there are m...
