CKD knowledge extraction flowchart. We use KS-CCD to extract structured information from TCM inpatient electronic medical records, including diagnoses, symptoms, syndromes, prescriptions, and treatment methods. Then, BERT-BILSTM-CRF and CMF-SEC are used to clean the symptom and prescription, respectively. Finally, combined with manual audit, the CKD knowledge base is constructed.
