TEXT CATEGORY RECOGNITION METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/005968
Kind Code:
A1
Abstract:
Provided in the present disclosure are a text category recognition method and apparatus, and an electronic device and a storage medium. The method comprises: splitting text to be recognized, so as to obtain a sub-text sequence, and splitting each piece of sub-text in the sub-text sequence, so as to obtain a corresponding sentence sequence; for each sentence in the sentence sequence corresponding to each piece of sub-text, performing feature extraction according to a pre-trained feature extraction model, so as to obtain a sentence feature vector corresponding to the sentence; for each piece of sub-text in the sub-text sequence, executing a first calculation operation to calculate an attention feature vector of the sub-text with respect to the text to be recognized; splicing the attention feature vectors of all the pieces of sub-text in the sub-text sequence with respect to the text to be recognized, so as to obtain a feature vector of the text to be recognized that corresponds to the text to be recognized; and inputting the feature vector of the text to be recognized into a pre-trained classification model, so as to obtain a probability value of the text to be recognized being a preset category of text. Therefore, text to be recognized is automatically classified, thereby reducing the labor costs of text classification.
