  rough set theory
Rough set axiomatization is one aspect of rough set study to characterize rough set theory using dependable and minimal axiom groups.
      
Thus, rough set theory can be studied by logic and axiom system methods.
      
The classical rough set theory is based on equivalence relation, but the rough set theory based on similarity relation has wide applications in the real world.
      
To characterize similarity-based rough set theory, an axiom group named S, consisting of 3 axioms, is proposed.
      
The reliability of the axiom group, which shows that characterizing of rough set theory based on similarity relation is rational, is proved.

This paper presents a representation language based on Rough Set theory,called RSL. This language has two parts: one is for application and the other for theory research. The application part is designed mainly for information analysis, such as data analyses and decision making. The research part tries to provide a tool for researchers on theory or on constructing more complicate algorithms. Finding the smallest reduction has been proved to be an NP-complete problem, a domain-independent approximate algorithm...

This paper presents a representation language based on Rough Set theory,called RSL. This language has two parts: one is for application and the other for theory research. The application part is designed mainly for information analysis, such as data analyses and decision making. The research part tries to provide a tool for researchers on theory or on constructing more complicate algorithms. Finding the smallest reduction has been proved to be an NP-complete problem, a domain-independent approximate algorithm is presented in this paper. It makes the RSL more suitable to deal with large information tables.

本文绘出了一种基于RoughSet理论的表示语言—RSL,该语言包括面向应用与面向研究两部分.应用部分主要服务于对信息表进行分析与处理的用户,研究部分则主要是为研究RoughSet及利用RoughSet理论构造更复杂算法的研究者所设计.鉴于RoughSet理论中求最小约简的过程是NP完全问题,为了使RSL表示语言可以分析与处理规模更大的信息表,本文还为RSL表示语言设计了一个新的对求取最小约简而言的领域独立的近似算法.

Data enriching is a kind of transformation that satisfies some equivalence condition, by whichthe database that is hard to read and reprocess can be translated to a much easier form. This paper discusses some problems and methods on data enriching in terms of rough set theory.

讨论了以RoughSet理论为工具的数据浓缩中的若干问题及方法。数据浓缩就是一种满足某种等价条件的变换,通过这种变换将繁杂且难以阅读理解或难以进一步处理的数据世界,变换为简洁且易于阅读理解或再处理的表示形式。

Rough Set theory is a new mathematical tool to deal with vagueness and uncertainty. This paper introduces the basic idea and characteristics of Rough Set theory.Several representative systems based on Rough Set theory are analyzed.

RoughSet理论是近年来出现的处理模糊和不确定性的数学工具,已广泛应用于人工智能的许多领域特别是KDD领域。文章介绍了RoughSet理论的基本思想,并着重讨论了几个基于RoughSet理论的典型KDD系统。
