面向KDD的粒度计算建模研究

给出了全粒度空间的拓扑结构模型，进一步介绍了面向粒度计算的产生式决策逻辑语言GDL-language，然后定义了面向粒度描述的正基语言，阐明该语言公式的语义解释，给出了一种“全粒度空间＋正基语言”的粒度计算模型，并找到了正基语言系统、粒度空间和基本概念空间的关系定理。最后，把KDD任务归结为基于该模型的粒度计算问题，这样就可以把各种KDD任务统一到一个理论框架下，也便于比较和研究。这些工作无疑对令后知识发现的研究起着重要的作用．

Research on Granular Computing Modeling for KDD

Topological structural model of AllGS is given,and GDL-language is further introduced for GrC(granular computing).Then L_(+base),a language for describing granules,is defined and its semantic explanation and a kind of gran- ular computing model are also presented.Some theorems between L_(+base),granular space and BCS(Basic Concept Space) are found.At last,the problems of KDD come down to ones of granular computing,and then KDD tasks become prob- lems in a theoretical framework,which leads to convenience for research on KDD.These work will be beneficial to fur- ther study on KDD.
