一种基于数据的一致性进行知识简约方法

A Simplification of Knowledge Based on Information Consistency of a Database

文章从基于条件属性等价划分与研究论域对象的覆盖率入手,提出了一种新的数据一致性概念,基于数据的一致性概念进行知识简化,比粗集理论中利用知识的依赖性研究知识简化概念更清楚,方法更简便。结合实例分析、处理大型的知识表达系统,研究经典CTR汽车数据库的知识简化,实验结果证明了本文方法的可行性和有效性。

Form view of the knowledge coverage rate, a new concept of information consistency of a database is presented based on condition attributes equivalent classification and the acquired objects in an information universe. A basic algorithm and realization of knowledge simplification on the information consistency of a database is suggested in this paper. It is more legible and convenient for knowledge simplification by way of the information consistency of a database than the theory knowledge dependence. A classic CTR car database with a large-scale knowledge representation system is studied by make use of the method proposed. The feasibility of the approach of knowledge simplification is validated by some of examples here.
