Phenomenon constituting knowledge space and granular structure models of its three categories

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.
