Abstract: As the basic means of traditional Chinese medicine (TCM) diagnosis and syndrome differentiation, the four-diagnosis of TCM has been further inherited and innovated under the empowerment of artificial intelligence in recent years. In this paper, we summarized the Chinese and English literature of the four-diagnosis intelligent research of TCM in the past ten years, analyzed its current research status, completed the visual analysis based on the knowledge graph, and further discussed the research hot-spots in this field. Finally, based on the existing research status, we proposed thinking and prospects for the next development of the intellectualization of the TCM four-diagnostics, in order to provide reference value and significance for the future research in this area.
