摘要
粒度计算的主要任务之一是如何利用不同粒度层次间的转换来抽象出我们感兴趣的知识,而概念格的格结构在层次转换方面的高效性对有效地进行粒度层次转换有重要指导意义。本文介绍了有关粒度计算与概念格理论的相关知识,并对粒度划分的格结构及相关性质进行了证明,分析了概念格与粒度划分格在概念描述与概念层次转换之间的联系。
One of the important purpose of granule computing is how to abstract the knowledge we are interested in among different granule levels by transforming, and the advantages of the structure of concept lattice have a significant guidance on how to transform among levels effectively. This paper introduces some related theories about granule computing and concept lattice, and following the demonstration of the granular partition lattice and its properties, analyzes the relationship on the description of concept between the two theories and the relationship on transforming among concept levels between the two theories.
