Classic rough set theory based on equivalence relation takes complete system as object of study , and divides the region into some non-intersect equivalence class; But, in the real life, because of the errors in data measuring, understanding of data, or the restriction in data collection , it can make the decision-making system incomplete, that is, value of attribution of some objects is unknown, which restrains development of the theory to practical direction.

经典粗糙集理论以完备系统为研究对象，以等价关系为基础，通过等价关系将论域划分为互不相交的等价类；然而，在现实生活中，由于数据测量的误差，对数据理解或获取的限制等原因，使得在知识获取时往往面临的是不完备系统，即可能存在部分对象的一些属性值未知的情况，这就极大地限制了粗糙集理论向实用化方向发展。

In the first place, on the base of studies concept ascending and attribute dependency, we forward a method to select attribute value partition, which can effectively resolve the problem of minimum faith and minimum support, in order to induct potential knowledge from standard discrete symbolic data, the dissertation studies join operation for generating candidate set and delete operation for deleting redundant equivalence class, and propose an recursion algorithm to realize highly generalization of data.

首先在研究概念爬升方法和Rough集理论中属性隶属度原理的基础上提出了一个划分属性值区间的算法，该算法能够有效的解决最小支持度问题和最小信任度问题。进而为了从已离散化的数据中概括出潜在的规则，研究了生成侯选集的交运算方法和排除冗余等价类的删除方法，然后利用循环推进机制实现对数据的概括。

To solve this problem,the equivalence relation of rough set theory is replaced by an asymmetrical similar relation,and from this relation,an asymmetrical similar matrix is defined,then a new heuristic algorithm with less space complexity that require core and knowledge reduction based on asymmetrical similar matrix is proposed,and an example is given to confirm the validity of the algorithm.

用非对称相似关系代替粗糙集理论中的等价关系，定义了非对称相似差别矩阵，提出了基于非对称相似差别矩阵的高效求核和知识约简算法。该算法无需改变初始不完备信息系统的结构，能直接处理缺省数据。实验结果表明，新算法所获得的决策规则简洁、高效，与缺省值无关。

经典粗集理论以等价关系为基础，它们在处理不完备信息系统的时候存在一定的局限性。

This equivalence relation, however, seems to be a very stringent condition that may limit the application domain of the rough set model.

此外，等价关系是经典粗糙集理论中最为关键和重要的概念，然而等价关系看起来是一个过强的条件，可能会限制了粗糙集模型的应用领域。
