To deeply analyze the research progress on the application of medical knowledge graph in the field of stroke, to discuss the problems of the development of stroke knowledge graph in China, and to put forward suggestions for the construction of stroke knowledge graph. Method/Process By reviewing and analyzing the relevant literature, the application of medical knowledge graph in the field of stroke is sorted out and summarized. Result/Conclusion There are still many deficiencies in the development of stroke knowledge graph in China, and in the future, in-depth research can be carried out from four aspects, namely, expanding the application scope of knowledge graph, promoting the fusion of knowledge graph, developing more efficient algorithms, and upgrading to cognitive graph by joint artificial intelligence (AI).
