A TCM Question and Answer System Based on Medical Records Knowledge Graph

In recent years, the combination of knowledge map and question and answer system are more and more applied in professional fields. In this paper, we firstly constructed a knowledge graph of traditional Chinese medical records which contains four entities: herbs, prescriptions, diseases, symptoms and their relationships; Secondly, we use Node2vec algorithm to represent the graph; Finally, we match questions and answers based on KNN. Experiment result shows that with the output of five prescriptions, our system's accuracy reaches 93.4%, which achieves good results.
