摘要/Abstract

摘要：

在研究概念知识粒和概念信息粒的基础上,进一步讨论了Ⅰ-型概念信息粒、Ⅱ-型概念信息粒和概念知识粒之间的转换关系,并给出了新的转化方法,进一步揭示了概念信息粒和概念知识粒之间的关系。这些结论为生成近似概念和获取近似规则提供了理论基础,促进了粒计算理论的发展。

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
