Abstract

The invention discloses a text classification method and device based on label description, a storage medium and equipment, and belongs to the field of text classification. The text classification method based on label description comprises the following steps: obtaining label description corresponding to each classification label according to semantics of each classification label; respectively inputting each label description and the to-be-classified text into a semantic analysis model, and respectively obtaining a probability value corresponding to each classification label to which the to-be-classified text belongs; and determining a classification label corresponding to the to-be-classified text according to a relationship between the probability value and a preset threshold value. According to the text classification method based on label description, the labels can have rich text semantics, so that model classification is better guided, and the classification accuracy is improved.

Description

technical field [0001] The present application relates to the field of text classification, in particular to a tag description-based text classification method, device, storage medium and equipment. Background technique [0002] With the rapid development of data collection technology and the rapid popularization of the Internet, the amount of text information that people come into contact with shows an explosive growth trend. In order to effectively manage and utilize these massive text information, and realize accurate text information location and text information filtering, text classification based on machine learning has received extensive attention in recent years. Text classification can be divided into single-label classification and multi-label classification according to the number of sample category labels. [0003] In the existing technology, the traditional text classification method directly sends the text to be classified into the semantic analysis model, an...
