基于互表性的动态本体体系结构的研究

Research on Architecture of Dynamic Ontology Based on Mutual-description Principle

摘要: 本体用于对客观世界的存在进行系统化描述,方便知识的重用、集成和交互.目前的本体理论认为概念的语义是确定不变的,事实上,概念的语义具有互相表示性(互表性),概念间的关系也具有模糊性和演化性,而关系之所以会演化是由于本体中有能动的成份———主体的存在.本文把主体的概念引入本体中使本体具有动态性,给出了本体的形式化定义,设计了动态本体的体系结构,并用XML对本体的成份进行了描述.

Abstract: Ontology used to describe the objective world,and it is convenient to knowlege reuse.The current ontology theory insist that the semantic meaning of a concept is invariable.In fact,the semantic meaning of a concept is mutual-descripted,besides,the relationships between things are fuzzy and evolutive which is caused by the existence of Agent.In this paper,we add the concept of Agent in ontology,put forward its formal definition,design the architecture of the dynamic ontology,and describe the component of ontology with XML.
