Abstract: The extraction, form and confidence degree of rules in information system is researched in this paper. From the view of non-classical logic, the mutual relationship of rules between fore and aft the reduction of information system is discussed here. Therefore, we can understand more deeply the characteristics and mutual relationship of every method of knowledge reduction.

Key words: information system, knowledge reduction, confidence degree of rule

摘要: 本文研究信息系统的规则提取问题,研究规则的形式、规则的可信度,从非经典逻辑的角度讨论信息系统约简前后规则的相互关系,进而更深入地了解各种知识约简方法的特点与相互关系。
