摘要
本体论概念层次构建是本体论工程的重要任务之一。通过分析本体论概念属性间的约束关系,借助于布尔方程衍生概念属性间的存在约束,提出了根据概念属性间存在约束关系构建本体论概念层次的方法,并在此基础上给出了本体论概念层次的维护算法。
Building ontology concept hierarchy is a important task of ontology engineering.This paper analyzes the restrict relations of ontology concepts attribute, uses bull function to derivate the existence restrictions of concept attribute and proposes a method of building ontology concept hierarchy according to the existence restrict relations of concepts attribute.At same time,an algorithm of maintaining ontology hierarchy is supposed based on it.
