摘　　要：多粒度数据是一种特殊的、有用的数据类型,它通过对论域(研究对象的集合)采用不同的粒化方式使得数据能够在多个粒度空间中进行呈现,在此基础上可以开展数据的多层次知识发现研究。商空间理论、序贯三支决策、多粒度粗糙集、多尺度数据分析模型和多粒度形式概念分析是几种常见的、有效的多粒度数据分析方法,已受到人们的广泛关注。本文对基于粒计算的多粒度数据分析研究工作进行综述,给出每一类多粒度数据分析方法的理论框架、基本概念以及主要研究思想,并指出多粒度数据分析研究中存在的若干问题,为该领域的后续研究提供理论参考。Multi-granularity data is a special useful type of data which is able to show data in different granularity spaces by using different granularity forms of a universe of discourse(i.e.a set of research objects),and then multi-level knowledge discovery can be studied based on multi-granularity data.As is well-known,quotient space theory,sequential three-way decision,multi-granulation rough set,multi-scale data analysis model and multi-granularity formal concept analysis are several common and effective multi-granularity data analysis methods,and they have attracted more and more people’s attention.This paper reviews the existing work on multi-granularity data analysis in granular computing,gives theoretical frameworks,basic notions and main research ideas for each kind of multi-granularity data analysis methods,and points out some problems for the further study of multi-granularity data analysis.The obtained results can provide a theoretical reference for future research of this field.
