Abstract

Aiming at the problem that people are afraid to choose Chinese medicines, do not know how to choose Chinese medicines and cannot use Chinese medicines correctly because of the lack of scientific understanding of Chinese medicine, a practical intelligent question and answer system of Chinese medicine knowledge was constructed. The system provides people with reliable and convenient Chinese medicine knowledge inspection and intelligent question answering service to improve the role of Chinese medicine knowledge in safeguarding people's health. Firstly, extract and clean the Chinese medicine knowledge in Chinese medicine books, set the extracted Chinese medicine knowledge as a specific format, and build a knowledge graph. Secondly, filter the natural language question, use Aho-Corasick multi-mode matching algorithm for keywords to extract, then use the cosine similarity algorithm to calculate the similarity calculation. Finally, match the question and answer template and generate the answer. Through the system test, it is proved that the system can satisfy the needs of users to obtain reliable Chinese medicine knowledge service quickly.
