一种基于十元格蕴涵代数的知识表示方法

摘要

不确定知识表示中常使用语言值来表达其真实程度和可信程度.为处理具有语言值可信度的不确定性知识表示问题,基于十元格蕴涵代数,建立一个十元语言值可信度因子知识表示模型,并实现了具有语言值可信度因子的知识推理.所提出的知识表示方法可以有效地表达具有可比性或不可比性的语言值不确定性信息.实例说明所提出的方法在表示知识时能够尽量模拟具有语言值信息的人类思维模式,有利于对不确定性知识的智能处理.%In uncertain knowledge representation, linguistic values are often used to express its truth degree and credibility. In order to deal with the uncertain knowledge representation issue with linguistic value credibility, in this paper we construct a knowledge representation model with ten-element linguistic value credibility factors based on ten-element lattice implication algebra, and achieve the knowledge reasoning with linguistic value credibility factors. The proposed approach for knowledge representation can effectively express both comparable and incomparable uncertainty information of linguistic value. Examples illustrate that the proposed approach can simulate human thinking mode with linguistic values information as much as possible, which benefits to the smart processing of uncertain knowledge.
