Abstract

Abstract:

Based on both concept knowledge granule and concept information granule, the relationships between Ⅰ-concept information granule and Ⅱ-concept information granule are discussed, and a new transformation methods are presented. The new method further uncovers the relationship between concept knowledge granule and concept information granule. Many important conclusions given in this paper provide basic theories for generating approximate concepts and acquiring approximate rules from concept lattice. These research work further develop the granular computing theory.

Key words: concept lattice; concept knowledge granule; concept information granule; information system; granular computing
