Problems solved by technology
[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, device and storage medium for a learner's cognitive structure, and relates to the field of computer technology. The processing method for the cognitive structure of the learner includes: obtaining the directed graph representing the knowledge point relationship and the item score of the first learner's evaluation; inputting the item score into the topic knowledge point mapping model to obtain the first learner's knowledge point cognition The first horizontal matrix; generate the second matrix according to the directed graph; concatenate the first matrix and the second matrix to obtain the third matrix; extract the cognitive level features and knowledge structure features of the knowledge points in the third matrix; use the graph convolutional neural network The knowledge point cognitive level features and knowledge structure features are fused with the autoencoder to obtain the first learner's cognitive structure representation matrix and the first learner's cognitive structure feature representation vector. The application can improve the accuracy of the learner's cognitive structure, thereby improving the accuracy and comprehensiveness of the analysis results based on the cognitive structure.
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...
