Abstract: Medical knowledge graph can provide new auxiliary information for recommendation system because of its structural semantic knowledge characteristics. The combination of recommendation system and medical knowledge graph can not only effectively alleviate the problem of sparse data, but also enhance the accuracy and interpretability of recommendation results, thus realizing personalized recommendation of medical information. Aiming at the characteristics of strong professional barriers and various conceptual terms in the medical field, the medical knowledge graph structure is systematically sorted out. This paper summarizes the traditional recommendation algorithms and compares their advantages and disadvantages. It summarizes and introduces the recommendation systems based on path, embedding and fusion respectively, focusing on the research results of combining medical practice and their advantages and disadvantages. The existing problems and challenges in current research are analyzed, and the feasible future research direction is prospected.
