【摘要】 针对现有本体表示方法在虚拟企业模型描述方面的不足,通过扩展本体关联语义和约束规则,提出一种适合虚拟企业模型的、图形化的本体表示模式——本体结构图。在分析虚拟企业模型及其特点的基础上,形式化定义了本体结构图的关联和约束规则,给出了虚拟企业模型片段的本体结构图的描述实例,并进一步提出了一种基于可扩展标记语言扩展的本体描述语言,说明了其基本元素和文档结构,描述了本体结构图的关联和约束。最后,通过与其他本体表示方法的比较,阐述了本体表示方法的可行性。更多还原

【Abstract】 Aiming at making up the lack of present ontology representation methods in describing virtual enterprise model,a graphic ontology representation schema,called Ontology Structure Graph(OSG),which adapted to describe virtual enterprise model was put forward.Based on the analysis of virtual enterprise model and its characteristics,semantic relationship and constraint rules of OSG were defined formally.An OSG instance of partial virtual enterprise model was given to illustrate in detail how to create an OSG.Furthermore,an ontology description language for virtual enterprise model which was expanded from eXtensible Markup Language(XML) was proposed.Its basic elements and document structure were illustrated,and its associations and constraints were described in particular.Finally,the feasibility and advantages of ontology representation method were analyzed through comparing to other ontology representation methods.更多还原
