Abstract:

Fundamental steps in ontological modeling methods are summarized. Based on the analysis of C2IEDM,the realization mechanism of the O-C2IEDM ontologica  l model using OWL is provided. Using the classes and attributes in OWL,the concepts and attributes of important independent entities in the model as wel l as the relations between the entities are described. Most constraints in C2IEDM are expressed by the definitions of domain, range and cardinality. Some of the model business rules are described by the relationships between Class and Subclass, and others are realized by the definition of the extended concepts for the model. It is testified in the realization of a real system. As a domain ontological model of the core-service layer in semantics-oriente d C4ISR/Sim integration systems, it provides the semantic information support for the model service description of the custom-service layer as well as t he problem description of the application layer, thus improves the intelligence and flexibility of integration systems.
