RS理论的领域知识颗粒构造问题研究

对RoughSet理论的知识运算原理进行了研究，得出基于该工具的知识发现其本质，是关于论域的知识颗粒间存在着知识包含关系。该关系使得知识存在着可被细化、可被推广泛化性质，表明只有用真实有效的原始知识资源开展的知识发现问题研究，其成果才具有可推广应用于指导工程实践自动决策的价值。因此，如欲基于粗糙集理论解决特定工程领域的知识获取难题，要解决的最基础问题应当是对原始知识资源实施满足粗糙集理论工具要求的妥善保护新问题。

Investigation to Build a Set of Domain Knowledge Particles with Rough Set Theory

The knowledge operation discovery with the tool was found,it is principle of Rough Set Theory was investigated. The nature to realize the knowledge to hold the knowledge inclusive relations in the knowledge over universe and sizes of the knowledge particles. The relations make the knowledge that can be reduced and enlarged. It is concluded that the knowledge discovery research based on original and true as well as effective data set can be generalized out the engineering applications. So, if to realize the knowledge discovery of an engineering domain with it, the protection of authentic and effectual knowledge resources about a special universe should be a basic investigation task firstly.
