Abstract

The invention provides a text emotion analysis method. The method comprises the steps that a text emotion analysis request carrying a target text is received, the target text is preprocessed, and a preset sequence annotation method is adopted to perform word segmentation processing on the preprocessed target text to obtain an available word set corresponding to the target text; a to-be-analyzed sentence of the target text is determined, an available word set corresponding to the to-be-analyzed sentence in the target text is acquired, and sentence vectors of the to-be-analyzed sentence are calculated according to preset calculation rules, wherein the sentence vectors include sentence-level vectors and word-level vectors; and the sentence vectors of the to-be-analyzed sentence are input intoa pre-trained emotion judgment model, and the emotion polarity of the target text is judged according to the model output result. The invention furthermore provides an electronic device and a computer storage medium. By use of the text emotion analysis method, the electronic device and the computer storage medium, the accuracy of target text emotion analysis can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a text sentiment analysis method, an electronic device and a computer-readable storage medium. Background technique [0002] For investment institutions and investors to formulate trading strategies, the analysis of corresponding texts of specific events or people is very necessary and useful. For example, by analyzing all the remarks of a certain person (for example, Mr. X) on twitter about the China-UK trade war, we can roughly understand his attitude towards the incident, which is very useful for China to make corresponding preparations in advance.
