[0003] At present, the cognitive structure determines a value based on the score obtained by the learner on a certain knowledge point to indicate the learner's mastery of a certain knowledge point, but there are different degrees of correlation between the knowledge points. Students' mastery of different knowledge points is not necessarily the same. Therefore, the cognitive structure of learners determined in this way is not accurate enough, and the analysis results based on the cognitive structure of learners are not accurate enough, which is not conducive to effective adjustment of teaching content. and way

The invention discloses a processing method, system and device for a learner cognitive structure and a storage medium, and relates to the technical field of computers. The method for processing the cognitive structure of the learner comprises the steps of obtaining a directed graph representing a knowledge point relationship and a question score evaluated by a first learner; inputting the question score into a question knowledge point mapping model to obtain a first matrix representing the knowledge point cognitive level of the first learner; generating a second matrix according to the directed graph; splicing the first matrix and the second matrix to obtain a third matrix; extracting knowledge point cognition level features and knowledge structure features in the third matrix; and fusing the knowledge point cognitive level features and the knowledge structure features through a graph convolutional neural network and an auto-encoder to obtain a cognitive structure representation matrix of the first learner and a cognitive structure feature representation vector of the first learner. According to the method, the accuracy of the cognitive structure of the learner can be improved, so that the accuracy and comprehensiveness of the cognitive structure-based analysis result are improved.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a processing method, system, device and storage medium for learners' cognitive structure. Background technique [0002] With the advent of the information age of education, how to achieve precise education through data-driven and carry out personalized assessment of learners has become a research hotspot, for example, apply cognitive diagnosis technology to quantify students' cognitive structure, and assist teachers to make remedies based on cognitive structure teaching. A large number of research results show that analyzing students' cognitive structure and carrying out targeted personalized tracking teaching can not only help teachers grasp the overall teaching effect, but also help teachers adjust teaching content and methods according to students' individual differences. , therefore, analyzing the cognitive structure of learners lays the foundation for personalized...
