Every day, the hospital has accumulated a large number of electronic medical records, which record the doctor's description of various patients' conditions, including a large number of medical knowledge related to the patient's health status. So intelligent retrieval research of EMR is an important extension of the medical field. Its accurate retrieval plays an important guiding role in research in the medical field. In this paper, we come up with the combination of rules and knowledge graph, and experimental results demonstrate that the electronic medical record retrieval method based on rules and knowledge map technology can significantly improve the retrieval effect.
