Science similar question recommendation method, device and equipment and readable storage medium

The invention relates to a science similar question recommendation method, device and equipment and a readable storage medium, and relates to the technical field of education, and the method comprises the steps: importing a to-be-processed test question into a test question text vector model, and obtaining a text feature vector of the to-be-processed test question; extracting a basic feature vector and a formula knowledge feature vector of a formula in the to-be-processed test question, and splicing the extracted basic feature vector and formula knowledge feature vector to obtain a formula feature vector of the to-be-processed test question; performing knowledge entity extraction on the to-be-processed test questions, and importing knowledge entities into the subject knowledge system model to obtain knowledge point feature vectors of the to-be-processed test questions; splicing and fusing the text feature vector, the formula feature vector and the knowledge point feature vector to obtain a comprehensive featu
