Problems solved by technology

It solves the problem that the existing technology cannot comprehensively consider the relationship between knowledge points, students and teaching resources, and it is impossible to mine potential associations between various entities through massive student learning behavior data. Through OCR algorithm, LSTM algorithm, TFIDF Algorithms match the corresponding knowledge points for the teaching resources and build the relationship between the teaching resources and the knowledge points, combined with the learning behavior of the students on different teaching resources to further maintain the students' mastery of the knowledge points and the preference of the learning resources

Abstract

The invention provides a multi-entity mixed knowledge graph construction method and device and a storage medium. According to the method, knowledge points, students and teaching resources are added into a knowledge graph as entities. Corresponding investigation knowledge points are matched for teaching resources through an OCR algorithm, an LSTM algorithm and a TFIDF algorithm, the relationship between the teaching resources and the knowledge points is constructed, and the mastery degree of the students for the knowledge points and the preference degree of the students for the learning resources are further maintained in combination with the learning behaviors of the students on different teaching resources.

Description

technical field [0001] The present invention relates to the field of online education and mixed education, in particular, to a method, device and storage medium for constructing a multi-entity mixed knowledge graph in the field of education. Background technique [0002] In the field of education, the entities of the knowledge map are generally limited to the chapters, sections and knowledge points of the subject itself. In the construction process, it is generally constructed manually, or through a hybrid construction method combining text recognition and expert identification. This traditional knowledge graph structure can effectively describe the detailed relationship between knowledge points and knowledge points in the subject, but the relationship between the teaching process and the students is weak, especially the various knowledge generated by the students in the learning process. Therefore, it is difficult to reflect the differences between different students and t...
