Mathematical question knowledge point classification method, device, readable storage medium and server

Abstract

The invention belongs to the technical field of computers, and particularly relates to a mathematical problem knowledge point classification method, a mathematical problem knowledge point classification device, a computer readable storage medium and a server. The method comprises the following steps of during the automatic classification process, for the characteristics for mathematical problems,adopting a multi-stage joint classification mode; embedding the automatic classification of each level of knowledge points into an organic interrelated processing process; when knowledge points of thenext level are classified, fully utilizing the knowledge points of the previous level for classified output. For example, when the second-level knowledge point classification is performed, the first-level knowledge point classification output is fully utilized. When the third-level knowledge point classification is performed, the second-level knowledge point classification output is fully utilized. The above process is repeated until the last-level knowledge point classification is completed. Therefore, the classification accuracy of the next-level knowledge points can be improved by utilizing the information of the previous-level knowledge points, the classification results of the knowledge points of all levels can be output at the same time in one process, and the classification efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method, a device, a computer-readable storage medium and a server for classifying knowledge points of math problems. Background technique [0002] At present, all companies in the market use manual classification to classify the knowledge points of math problems in the question bank. However, whether it is in elementary school, junior high school or high school, there are millions of math questions in the question bank, and the number of knowledge points involved reaches hundreds or even thousands. Traditional manual classification is not only costly, but also inefficient , The accuracy rate is low, and large-scale data classification cannot be performed. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a method, device, computer-readable storage medium, and server for classifying knowledge points of math probl...
