Embodiment 1

[0063] see figure 1 , figure 1 It is a schematic flowchart of a knowledge point intelligent diagnosis method disclosed in an embodiment of the present invention. Among them, the method described in the embodiment of the present invention is applicable to intelligent terminals such as learning machines, tutoring machines, tablet computers or mobile phones; of course, it is also applicable to high-speed computing devices such as desktop computers, portable computers and servers. Such as figure 1 As shown, the knowledge point intelligent diagnosis method includes the following steps:

[0064] 110. Use the teaching resource library to create a subject knowledge map.

[0065] Concepts, definitions, theorems, properties, formulas and other domain terms in the teaching resource library are used as entities in the map, and the association relationship between entities (knowledge points) is extracted and constructed to generate a subject knowledge map. Create different subject know...

Embodiment 2

[0091] see image 3 , image 3 It is a schematic flowchart of another knowledge point intelligent diagnosis method disclosed in the embodiment of the present invention. Such as image 3 As shown, the knowledge point intelligent diagnosis method includes the following steps:

[0092] 210. Use the teaching resource library to create a subject knowledge map.

[0093] 220. Acquire current user information and corresponding learning records, and determine weak knowledge points and mastered knowledge points of the current user.

[0094] 230. Project the weak knowledge points and mastered knowledge points into the subject knowledge graph to generate the personal knowledge graph of the current user.

[0095] 240. Traverse each knowledge point of the personal knowledge map, predict mastery information of unknown knowledge points, and obtain final weak knowledge points of the current user.

[0096] Steps 210-240 are similar to steps 110-140 in Embodiment 1, and will not be repeated...

Embodiment 3

[0111] see Figure 4 , Figure 4 It is a structural schematic diagram of a knowledge point intelligent diagnosis device disclosed in an embodiment of the present invention. Such as Figure 4 As shown, the knowledge point intelligent diagnosis device can include:

[0112] The creation unit 310 is used to create a subject knowledge map using the teaching resource library;

[0113] An acquisition unit 320, configured to acquire current user information and corresponding learning records, and determine weak knowledge points and mastered knowledge points of the current user;

[0114] A projecting unit 330, configured to project the weak knowledge points and mastered knowledge points into the subject knowledge map to generate the personal knowledge map of the current user;

[0115] The predicting unit 340 is configured to traverse each knowledge point of the personal knowledge graph, predict mastery information of unknown knowledge points, and obtain final weak knowledge points...

Abstract

The embodiment of the invention relates to the technical field of knowledge reasoning, and discloses a knowledge point intelligent diagnosis method and device, electronic equipment and a storage medium. The method comprises the following steps: creating a subject knowledge graph by utilizing a teaching resource library; obtaining current user information and a corresponding learning record, and determining weak knowledge points and mastered knowledge points of the current user; projecting the weak knowledge points and the mastered knowledge points into the subject knowledge graph to generate apersonal knowledge graph of the current user; and traversing each knowledge point of the personal knowledge graph, and predicting mastering information of unknown knowledge points to obtain all finalweak knowledge points of the current user. By implementing the embodiment of the invention, the weak knowledge points in the questions can be identified through the learning record of the current user, and more weak knowledge points of the user are predicted in combination with the technology of the knowledge graph, so that the intelligent diagnosis of the knowledge points of the current user iscompleted, and more defects of the knowledge points are found out.

Description

technical field [0001] The invention relates to the technical field of knowledge reasoning, in particular to a method, device, electronic equipment and storage medium for intelligent diagnosis of knowledge points. Background technique [0002] As an indispensable resource in the education system, knowledge points have become the focus of current educational data mining research. As a powerful means to test learners' mastery of knowledge points, exercises play an important role in the research of knowledge point recommendation. Exercises can determine which knowledge points learners have mastered, which knowledge points are wrong, and the degree of weakness of knowledge points. how. [0003] Existing judgments on learners’ weak knowledge points are still reflected by the error rate based on each knowledge point after a large number of exercises. point, it is impossible to determine its degree of mastery. Contents of the invention [0004] In view of the above defects, th...
