Research on Multi-level Recommendation Method of Medical Rehabilitation Teaching Resources Based on Gray Correlation Method

Aiming at the problem of low recommendation cover age rate and low recommendation accuracy due to the small recommendation range of medical rehabilitation teaching resources, a multi-level recommendation method of medical rehabilitation teaching resources based on grey correlation method was proposed. According to the actual recommendation needs and standards, we recommend and classify basic medical rehabilitation teaching resources, expand the scope of recommendation, build a multi-level teaching resource recommendation structure, design a gray relational medical rehabilitation resource recommendation model, and implement resource recommendation through collaborative filtering. The final test results show that for the six objectives, the recommended coverage can reach more than 80%, the recommendation accuracy rate reached 97.5%, indicating that this teaching resource recommendation method is highly targeted and stable, with a large precision and coverage, and has practical application value.
