The invention discloses a knowledge point recommendation method and device based on a knowledge graph, a storage medium and an electronic device. The knowledge point recommendation method comprises the following steps: generating a knowledge graph by referring to a constructed subject hierarchy model and a knowledge point mapping relationship; and through a knowledge connectivity algorithm based on the knowledge graph, determining the knowledge connectivity between the learned knowledge points and the knowledge points to be learned of the target user. The knowledge point recommendation method and device solve the technical problems of low recommendation precision and incapability of well meeting the requirements of users for knowledge points due to incapability of performing knowledge point recommendation based on knowledge connectivity.
Description
technical field [0001] The present application relates to the field of learning resource recommendation, in particular, to a method, device, storage medium and electronic device for recommending knowledge points based on knowledge graphs. Background technique [0002] The inventor found that recommending learning resources to learners only considered the degree of interest of the learners, and did not consider the objective learning sequence of different knowledge points, nor did it consider the structure and characteristics of subject knowledge, so it could not be based on knowledge connectivity Recommend knowledge points; resulting in low recommendation accuracy, and cannot well meet the user's requirements for knowledge points. [0003] Aiming at the problem of low recommendation accuracy caused by the inability to recommend knowledge points based on knowledge connectivity in related technologies, and the inability to well meet the user's requirements for knowledge points...
