Abstract:
Objective :To construct a traditional Chinese medicine (TCM) knowledge base using knowledge graph based on deep learning methods, and to explore the application of joint models in intelligent question answering systems for TCM.
Methods:Textbooks Prescriptions of Chinese Materia Medica and Chinese Materia Medica were applied to construct a comprehensive knowledge graph serving as the foundation for the intelligent question answering system. In the study, a BERT+Slot-Gated (BSG) deep learning model was applied for the identification of TCM entities and question intentions presented by users in their questions. Answers retrieved from the knowledge graph based on the identified entities and intentions were then returned to the user. The Flask framework and BSG model were utilized to develop the intelligent question answering system of TCM.
Result:A TCM knowledge map encompassing 3 149 entities and 6 891 relational triples
based on the prescriptions and Chinese materia medica was drawn. In the question answering test assisted by a question corpus, the F1 value for recognizing entities when answering 20
types of TCM questions was 0.996 9, and the accuracy rate for identifying intentions was
99.75%. This indicates that the system is both feasible and practical. Users can interact with
the system through the WeChat Official Account platform.
Conclusion:The BSG model proposed in this paper achieved good results in experiments by
increasing the vector dimension, indicating the effectiveness of the joint model method and
providing new research ideas for the implementation of intelligent question answering systems in TCM.
