Granular Sets and Granular Relations: Towards a Higher Abstraction Level in Knowledge Representation
Antoni Ligęza · 2002
In this paper some ideas about granularity of data and knowledge are put forward. The concepts of a granular set and granular relation are defined and some algebraic operations on them are outlined. Granular data representation with a varying preciseness is a key issue in moving the knowledge representation and manipulation operations to a higher level of abstraction.
