Study on the construction and application of knowledge graph of classified prescriptions in Treatise on Febrile Diseases
Objective Based on the classification system of classical prescriptions,to construct the knowledge graph of Treatise on Febrile Diseases,providing ideas and references for the research on knowledge representation and classified prescriptions of Treatise on Febrile Diseases with classic prescriptions as the main focus.Methods Under the guidance of the Domain ontology seven-step method,concepts and relationships were extracted,pattern layer was constructed,and knowledge extraction was carried out under the constraints of pattern layer.Finally,Neo4j graph database and Python programming software were applied to import the extraction results,and knowledge graph was constructed to visually display the knowledge and correlation of classified prescriptions of Treatise on Febrile Diseases.And through taking the prescription of gardenia tempeh soup as a concrete example,the role of knowledge graph in the analysis and research of classified prescriptions.Results In this study,16 categories of concepts,15 object attributes,4 data attributes,and 1 relationship attribute were constructed and extracted in the pattern layer.A total of 4,300 nodes and 5,227 relationships were imported into the case layer to form the knowledge graph of Treatise on Febrile Diseases related prescriptions,which could be visually displayed and queried based on Cypher statements.By comparing the similarity and difference of prescription composition and symptoms in the form of knowledge graph,the development law of the prescription can be analyzed more directly and quickly.Conclusion The construction of knowledge graph with classified prescriptions system as the core framework is conducive to the study of Treatise on Febrile Diseases and exploration of prescription knowledge with prescriptions and syndrome as the clue,and can also lay a foundation for the design and application of online learning system of Treatise on Febrile Diseases.
