In order to solve the issues of the large scale and various forms of the knowledge information in the aircraft design, a model construction method of the knowledge organization based on ontology is proposed. Firstly, the concepts of the knowledge organization and the ontology are introduced. Then an ABC feedback method based on ontology is proposed. An application example of the knowledge organization in aircraft design is also given to verify the correctness and validity of the modeling method. Finally, the advantages of the ontology-based knowledge organization model are summarized.
