Aviation Equipment Fault Information Fusion Based on Ontology
Yuan Wang, Qing Li, Yong Sun, Jinliang Chen · 2014
The designing institution, manufacturer and end-user jointly participate in aircraft maintenance.Maintenance data from multiple sources results in syntax and semantic conflicts, which have restricted integration and sharing of information on aircraft faults.To solve this problem, a solution based on ontology is proposed.Global aircraft fault ontology gives a uniform and specific description for multi-source data, eliminating the semantic heterogeneity.Data integration based on ontology mapping eliminates the structural heterogeneity.Ontology reasoning and data fusion algorithm is proposed and successfully implemented to remove the ambiguity and inconsistence from information on aircraft fault.
