摘要: |
为建立时间维度下知识运动及演化的动态模型,将现象理解为构成知识的基本要素,并将概念、直
观(时间一状态)及关联逻辑作为组成现象的基本范畴,同时将粒结构作为现象形式化表示的基本结构.基
于形式概念分析与粗糙集理论之间的同构关系建立了现象中概念范畴及直观范畴的粒结构模型,并给出了
形式化现象之间的关联关系及关联逻辑,结果表明:基于对现象的形式化表示,可以构建比概念模型在语义
描述上更完整的知识表示模型 |

Abstract: |
To establish the dynamic models of knowledge movement and evolution under time dimension, the
phenomenon was understood as the basic element to constitute knowledge in this study, where the concept, in-
tuition ( time-state) and relevance logic were taken as the basic categories of phenomenon composition, and
meanwhile the granular structure was taken as the basic structure of phenomenon formalized representation.
Based on the isomorphism between formal concept analysis and rough set theory, the granular structure models
were established in concept and intuition category of phenomenon, and the correlation and relevance logic were
given among formalized phenomena. Based on the formalized representation of phenomenon, the knowledge
representation model can be established more completely than conceptual model in semantic description. |
Key words: formal concept anaylsis rough set knowledge space phenomenon |
