The distributed interactive modeling process requires a lot of staff participationthereby causes waste of resources and inefficiency for largescale simulation system.To solve the problem we proposed a semanticoriented distributed interactive modeling method.This method improves the current federation development process of High Level Architecture (HLA)and introduces the concept of ontology and semantic mapping in it.The federation development process is divided into three subprocedures as domain ontology constructionsemantic mapping and code generation.A concrete example demonstrates the feasibility and effectiveness of the method.
