Problems solved by technology

[0003] But even if the theory of knowledge space is applied to sort out relevant knowledge points, because of the huge amount of data, it is impossible to fully grasp the correlation between each knowledge point, so it is very difficult in the actual operation process

Abstract

The embodiment of the invention belongs to the technical field of information correlation verification, and relates to a method for determining knowledge point correlation values in a knowledge space.The method comprises the following steps: according to a preset important value of a knowledge point under a node and a correlation value among all knowledge points under the node, determining the node, determining related values of all knowledge points under the node to the node, wherein correlation values among part of the knowledge points are known, and the knowledge points with unknown correlation values are replaced by a value approximate to 0, and the correlation values are unidirectional effective values; updating the correlation values among the knowledge points under the nodes according to the important values of the knowledge points under one node and the correlation values of all the knowledge points under the nodes to the nodes; repeatedly determining the correlation value between the knowledge points under the node and the node and the correlation value between the knowledge points until the correlation value between the knowledge points under the node is stable. According to the method, only part of data is required, and the effect of obtaining the correlation values among all knowledge points through algorithm operation can be achieved.

Description

technical field [0001] The present application relates to the technical field of information correlation verification, and in particular to a method, device, computer equipment, and storage medium for determining correlation values ​​of knowledge points in a knowledge space. Background technique [0002] In the information age, a large amount of information needs to be processed. In the knowledge space model, information is abstracted into multiple knowledge points in the information space. The knowledge points are not independent of each other, but are related. It needs to be comprehensively processed according to the correlation between knowledge points to realize the effective application of knowledge points. In an application scenario, schools and training institutions need to consider the knowledge points in a subject, so as to prepare for the collection of students’ knowledge points during the teaching process. The mastery of some knowledge points, judge the mastery of...
