Research on Construction and Application of TCM Knowledge Graph Based on Ancient Chinese Texts

At present, the "document-centered" literature retrieval and information acquisition methods can no longer meet the demand, and instead are "knowledge-centric" structured, networked and intelligent knowledge services. In order to more effectively analyze the connection between Chinese medicine knowledge, optimize the retrieval of knowledge, share knowledge in the field of Chinese medicine, and make Chinese medicine better carry on. This paper builds a knowledge graph based on the texts of ancient traditional Chinese medicine books through the key concepts of diseases, symptoms, prescriptions, drugs, medical records, and related content such as regions, doctors, and dynasties in traditional Chinese medicine texts, to form a comprehensive knowledge service system, providing multi-dimensional and personalized knowledge customization services.
