Research on the Knowledge Ontology Model of Attribute-oriented Airworthiness Review Compliance Activities

The civil aviation management department reviews airworthiness certification for aircraft products to ensure the airworthiness of aircraft products. The complexity of aircraft products and the characteristics of the airworthiness certification work determine that the airworthiness certification work requires that the certification reviewer need to have rich knowledge and experience in airworthiness domain. If these knowledges can be reused, it will effectively improve the airworthiness certification capability. Airworthiness compliance activities are the core of knowledge reuse. Therefore, in order to solve the problem of the accuracy of knowledge reuse in airworthiness compliance activities, based on the existing compliance activity ontology model, this paper further refines the model and constructs an attribute-oriented ontology model of airworthiness review compliance activity knowledge. At the same time, the attributes of compliance activities are introduced into the similarity measurement of compliance activities to form a new measurement method for calculating the similarity of compliance activities. This paper uses this model as a guide to construct a process-oriented airworthiness review compliance activity knowledge base and use it to recommend similar compliance activity cases. The test results show that this method can improve the judgment of the similarity of compliance activities and more effectively support the reuse of certification experience in the airworthiness certification process.
