Abstract

The invention relates to data analysis, and provides a question recommendation method, which comprises the steps of collecting historical answer data of a student side, and predicting a first masterydegree of the student side for learned knowledge points through a deep knowledge tracking model; according to the learning time of the learned knowledge points and the forgetting curve, obtaining theforgetting degree of the knowledge points by the student side; combining the first mastery degree and the forgetting degree of the knowledge points by the student terminal to predict the second mastery degree of the learned knowledge points by the student terminal; extracting question related information according to the historical answer data of the student terminal and the second mastery degreeof the learned knowledge points; predicting a first correct rate of the student terminal on the condition that the student terminal does not do the question according to the Bayesian model through thequestion related information; sorting the questions which are not done according to the first correct rate, and selecting a first set number of questions sorted in the front to push to the student side. The invention further provides an electronic device and a storage medium. Different questions are recommended according to the knowledge point mastery degree of different students.

Description

Technical field [0001] The present invention relates to the technical field of data analysis, and more specifically, to a topic recommendation method, device and medium. Background technique [0002] Existing industry organizations will arrange various winter and summer vacation activities. In addition, students have more free time during winter and summer vacations. Schools and parents have little control over students, and there is a lack of products on the market to control student learning. In addition, the existing winter and summer exercises on the market all appear in the form of traditional exercise books. This form of unified purchase of exercise books and distributed to students has the following defects: [0003] The topics recommended for different students are the same, and it is impossible to recommend topics based on different students' different knowledge points, and it is impossible to recommend different topics based on different students' different weak current ...
