Objective: To realize the sharing and reasoning of knowledge in the field of Chinese medicine asthma by ontology. Method: Based on seven-step method from Stanford university

the disease ontology of asthma which included axioms was constructed by realizing the knowledge of asthma-related knowledge

and the relationship between some concepts. Result: The ontology construction of Chinese medicine asthma field was completed

which could realize the sharing of knowledge and simple reasoning

containing 102 classes

425 individuals

18 object properties

6 inverse properties

2 data properties

1 equivalent class axiom and 138 subclass of axioms counts. Conclusion: The construction of ontology has a certain value in the co-construction of knowledge and the semantic retrieval and data mining of the future knowledge base.
