The invention discloses a space-time fusion knowledge tracking method based on
large model annotation enhancement, and the method comprises the steps: firstly collecting and sorting historical interaction data of students in an intelligent teaching
system, and determining questions, knowledge points and a corresponding relation thereof; and then various relationships among knowledge points are labeled through a
large model, an initial graph is constructed, units and relationships among the units are labeled, then a labeling result is detected and optimized, and errors are corrected so as to improve the labeling quality. Then, knowledge point embedding is processed through a
time sequence learning module based on an attention mechanism, question embedding is obtained in combination with difficulty, and a
time sequence embedding code is obtained; and
feature extraction, integration and comparative learning are carried out through the fusion learning module. And finally, node embedding is dynamically updated based on the unit
relation graph, various information is fused, and a
loss function is predicted and calculated by using a neural network in combination with a
forgetting factor. According to the method, the accuracy and
interpretability of knowledge tracking are improved, and personalized teaching is assisted.
