【摘要】 本文总结了本体建模方法的基本步骤,并在分析C2IEDM模型的基础上提出了应用本体描述语言OWL改进性地实现C2IEDM,即O-C2IEDM的机制。应用OWL中类和属性实现了模型重要独立实体的概念、属性、实体间关系的描述,并灵活应用域、范围和势等概念表达了C2IEDM中的约束,通过类与子类的概念和定义引申概念实现了模型中业务规则的描述。O-C2IEDM在实际系统实现中的应用证明了它的有效性,在面向语义的C4ISR/Sim集成系统中,它作为核心服务层的领域本体模型,为定制服务层的各类模型服务描述以及应用层的问题描述提供了语义信息支持,提高了集成系统的智能性和灵活性。更多还原

【Abstract】 Fundamental steps in ontological modeling methods are summarized. Based on the analysis of C2IEDM,the realization mechanism of the O-C2IEDM ontological model using OWL is provided. Using the classes and attributes in OWL,the concepts and attributes of important independent entities in the model as well 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-oriented C4ISR/Sim integration systems, it provides the semantic information support for the model service description of the custom-service layer as well as the problem description of the application layer, thus improves the intelligence and flexibility of integration systems.更多还原
