Ontology Modeling of Aircraft Fault Knowledge

Abstract

With consideration of the actual requirement of fault knowledge management in current aviation maintenance, ontology-based knowledge representation method of aircraft fault is studied. Knowledge sources of aircraft fault ontology are analyzed based on ontology modeling primitives. Ontology construction method of aircraft fault knowledge is proposed learning from software engineering and the essence of the existing ontology construction methodology. On the basis of the above study, aircraft fault ontology which is consist of Fault Core sub-ontology, Product domain sub-ontology, Case domain sub-ontology, and Diagnosis domain sub-ontology is build, and it represents aircraft fault knowledge completely and consistently, and also lays the foundation for knowledge management of aircraft fault.

Semantic Retrieval for Ontology-Based Aircraft Fault Knowledge

“…Ontology of aircraft fault is a kind of model using ontology modeling techniques to express and organize aircraft fault knowledge. Previous studies [1] proposed domain ontology of aircraft fault knowledge is composed by product domain ontology, case domain ontology , fault diagnosis domain ontology and fault core domain ontology that reflect the essential characteristics of the fault, and there are areas of overlap between the various sub-ontology using OWL (Web Ontology Language) [2] ontology language to construct.…”

“…To solve this problem, the semantic search technology is a popular resolution which from the conceptual level to understand and extend the user's search requests, thereby improving the retrieval effect. Based on the preliminary research of ontology modeling of aircraft fault knowledge [1], semantic retrieval for ontology-based aircraft fault knowledge is studied.…”
