Text classification number determination method and apparatus, and electronic device

Abstract

The invention provides a text classification number determination method and device and electronic equipment, and relates to the technical field of computers. The method comprises the following steps:respectively inputting to-be-classified texts into a first classification model and a second classification model to obtain a first-level target classification number obtained through the first classification model and a second-level target classification number obtained through the second classification model; matching the first-level target classification number with the second-level target classification number; according to a matching result, determining at least one sub-classification model in a third classification model, the sub-classification model having a corresponding relationshipwith the target level classification number; respectively inputting the text to be classified into each sub-classification model, and determining a first parameter calculation result of each sub-classification model; and determining a target sub-classification model from the at least one sub-classification model according to the first parameter calculation result, and taking a target level classification number corresponding to the target sub-classification model as a classification number of the to-be-classified text. According to the invention, accurate classification of the to-be-classifiedtext can be efficiently realized.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, the present application relates to a method, device and electronic equipment for determining a text classification code. Background technique [0002] The Chinese Library Classification: Chinese Library Book Classification, is a common tool for classifying documents in my country at present. The categories in the Chinese Library Classification include category numbers and category names. Category names refer to the names of book classifications. Book classification numbers (ie Class number) is a mixed number that combines English letters and Arabic numerals. One letter represents a major category, and the order of the major categories is reflected in alphabetical order. The subdivided disciplines under the major categories are mostly composed of Arabic numerals. [0003] The current method of automatically classifying documents relies on the construction of the knowl...

Problems solved by technology

Due to the huge category system in the Chinese Library Classification, the existing document classification methods are usually developed for some categories of the Chinese Library Classification, and only a relatively simple text automatic classification method is used, and the accuracy of book classification is not high
