Research on the promotion of implementation of clinical practice guidelines(IV): knowledge extraction, storage and example presentation of a knowledge garph for clinical guidelines for Traditional Chinese Medicine/Integrated Traditional Chinese and Western Medicine

In this study, based on the characteristics of Traditional Chinese Medicine (TCM) diagnosis and treatment and TCM clinical guidelines, knowledge extraction and knowledge storage were carried out to construct a knowledge graph depicting Traditional Chinese Medicine/Integrated Traditional Chi-nese and Western Medicine (IM) clinical guidelines using the "Guidelines of the Traditonal Chinese Medicine management of stable angina pectoris in coronary artery disease" as an example. This enabled us to further test the operability and rationality of the application of knowledge graph technology to the field of TCM/IM guidelines. The graph was constructed using the design of the concept layer and the da-ta layer, extracting entities and relationships from the guidelines, sorting them into the entity database and triple relationship databases for knowledge importation, using neo4j for knowledge storage, re-trieving and verifying the correctness of the knowledge graph, and completing the visual display. The methods used in constructing the knowledge graph for this clinical guideline also provides a template for the construction of knowledge graphs for TCM/IM clinical guidelines for other diseases.
