Knowledge graph construction method based on knowledge point connection relation

Abstract

The invention provides a knowledge graph construction method based on a knowledge point connection relation and belongs to the field of education and learning. The method comprises steps as follows: acquiring meta-knowledge points, and establishing a knowledge point database comprising the meta-knowledge points; selecting the meta-knowledge points according to content characterizing teaching knowledge points and a basic knowledge point combination having dependence relationships with the meta-knowledge points; determining path length of each meta-knowledge point, relative to a first meta-knowledge point, in the basic knowledge point combination; constructing the knowledge graph according to the dependence level and the path length. On the basis of the content, a net-like relationship graphcontaining the dependence relationships and path length values corresponding to the dependence relationships is drawn, then the knowledge graph is obtained, the meta-knowledge point with the highestcorrelation with the first meta-knowledge point can be determined at any time in the learning process, so that effects of making up the deficiencies and drawing inferences are achieved in the learningprocess, the probability of occurrence of learning blind areas is reduced, and finally, effectiveness of learning is enhanced.

Description

technical field [0001] The invention belongs to the field of education and learning, and in particular relates to a knowledge graph construction method based on knowledge point connection relationships. Background technique [0002] With the development of the network, the user's learning process is gradually transformed into a process of summarizing knowledge points. However, there is currently no relatively complete method of summarizing knowledge points, which makes it difficult to sort out the learning process. Contents of the invention [0003] In order to solve the shortcomings and deficiencies existing in the prior art, the present invention provides a knowledge map construction based on the knowledge point connection relationship that can incorporate knowledge points associated with teaching needs into the knowledge map, taking into account the weight of each knowledge point method. [0004] In order to achieve the above-mentioned technical purpose, the present in...
