MDR概念系统注册及本体表示标准化研究

随着大数据与人工智能在各个领域的深入应用,知识表示的标准化问题被提到了重要的日程。为实现知识表示的标准化,引入了现实世界、概念世界与计算机世界3个世界模型,明确阐述了将现实世界中的事物通过抽象,将其转化为概念世界中的概念系统模型,依据标准将其转化为计算机世界中的信息模型,从而实现知识表示。为了使概念系统模型表示规范化,重点研究了ISO/IEC 11179 MDR系列标准,剖析了其中的概念系统注册元模型规范,构建了MDR概念系统的七元组模型,同时还定义了概念间关系表示方法,为概念系统模型的表示奠定了基础。为了将注册在MDR中的概念系统模型转为计算机世界中的OWL本体表示模型,定义了将MDR概念系统向OWL本体映射的规则。最后,设计并开发了概念系统注册原型系统,验证了MDR概念系统和本体表示的可行性。研究成果为领域知识表示的标准化提供了方法论。

Research on MDR Concept System Model and Ontology Representation Standardization

With the in-depth application of big data and artificial intelligence in various fields, the standardization of knowledge representation has been mentioned as an important agenda. In order to realize the standardization of knowledge representation, this paper introduces the concept of Three Worlds model, that is, the real world, the conceptual world and the computer world. According to this model, things in real world can be abstracted concept in concept system model in concept world. Finally, acoording to concrete standards, the concept system model can be tanslated into information model in computer world, so as to realize knowledge representation. In order to standardize the representation of conceptual system model, series standards of ISO/IEC 11179 MDR is studied, the concept system registration meta-model specification is analyzed, and a seven tuple model of MDR concept system is constructed. In addition, the representation method of the relationship between concepts is defined, which lays the foundation for the representation of conceptual system model. In order to transform the concept system model registered in MDR into OWL ontology representation model in the computer world, the rules of mapping MDR concept system to OWL ontology is defined in the paper. Finally, the concept system registration prototype system was designed and developed to verify the feasibility of the MDR concept system and ontology representation. The research results provide a methodology for the standardization of domain knowledge representation.
