Embodiment Construction

[0026] According to one or more embodiments, such as figure 1 As shown, a method for automatically extracting knowledge points and problem-solving methods in elementary mathematics topics includes the following steps:

[0027] S100, performing natural language understanding on the elementary mathematics topic text, and finally extracting it into a predicate representation to obtain an initial data set;

[0028] S200, inserting the initial data set into the drools fact database, combining the drools reasoning engine and the symbolic computing system, using automatic reasoning technology to train the initial data set, and obtaining a rule set;

[0029] S300, according to the mapping relationship between the rules and various knowledge points and problem-solving methods, automatically extract and label the text of the math problems, and extract all the knowledge points and problem-solving methods contained in each elementary math problem.

[0030] The elementary mathematics ment...

Abstract

The invention discloses a method for automatically extracting knowledge points of mathematical problems and solving problems. The method comprises the following steps that: step S1, natural language understanding processing is conducted on mathematical question texts, and a processing result serves as an initial data set; S2, an initial data set is trained by using automatic reasoning in combination with a drools reasoning engine and a symbol calculation system to obtain a rule set; and S3, according to mapping between rules in the rule set and the knowledge points and the problem solving methods, the knowledge points and the problem solving methods contained in each mathematical problem are removed. The method can be used for providing accurate topic recommendation for students, a teachercan conveniently know knowledge points which are not mastered by the students and the types of the methods, and a tutoring plan can be made for the students in a more targeted mode.

Description

technical field [0001] The invention belongs to the field of education technology, and in particular relates to an automatic extraction method, device and platform for knowledge points and problem-solving methods of math problems. Background technique [0002] With the continuous and in-depth development of artificial intelligence technology in various education fields, precise education and personalized education have become an inevitable trend in the future development of the education market. Among them, for the important basic subject - mathematics, comprehensive and accurate extraction of knowledge points and problem-solving methods in mathematics problems is a technical difficulty to be solved. [0003] At present, most of the knowledge points and problem-solving methods of the existing mathematics question bank are edited and marked by professional teachers. It needs to consume a lot of manpower and material resources, and even the effect of automatic extraction is n...
