文中提出模糊概念空间及规则空间,作为对知识系统进行形式化表示的统一框架.首先,基于形式概念分析理论以及L模糊集构造了概念粒,通过对概念粒之间关联关系的研究定义了概念射,进而构造了高层次知识单元“概念粒簇”.概念粒簇由不同概念粒聚合而成,作为模糊概念空间中的结构层次.其次,通过定义概念粒之间语义整合的先验规则以及积运算构造了规则空间,阐明了概念粒在规则空间的作用下相互之间进行信息传播的机制.文中的结论为进一步研究模糊语义下知识系统的动态构成及演化机制奠定了理论基础.
This paper presents the Fuzzy Concept Space and the Rule Space as the unified formal framework to represent knowledge system.First,constructs the concept granule based on the Formal Concept Analysis theory and L Fuzzy Set.According to the relevance relation among concept granules,the concept mapping is defined,and then constructs "concept granule cluster" as high level knowledge unit is constructed.The concept granule cluster is integrated by different concept granules,and composites the structure hierarchy of the Fuzzy Concept Space.Next,the Rule Space is built by defines the priori rule and product operation that used in the semantic inte gration of different concept granules,thereby,clarifies the information transmission mechanism of concept granules under the action of Rule Space.The results of this paper provide theoretical basis for the research of the dynamic construction and evolutionary mechanism of knowledge system based on fuzzy semantics.
