| 摘 要： | 针对传统缺省规则知识挖掘算法易出现规则繁复、提取和存储不便等不足，提出了基于泛化分配表(GDT)和约简概念格(CL)优势互补的GDTCL缺省规则挖掘模型.模型采用GDT求取条件属性的属性子集，有效地解决了利用粗集理论进行求解会面临的NP问题.利用扩展概念格来表达GDT泛化层次的蕴含关系及规则强度和支持度的限制关系，通过概念格的约简算法完成缺省规则的挖掘.最后，进行了矿山缺省规则知识发现的实例验证，结果表明，该模型能从不完整矿山信息系统中挖掘出规则长度齐整、易于存储和应用匹配的无重复缺省规则.

| Abstract: | For overcome the shortcomings of traditional mining default rules algorithm,such as complex rules,extraction and storage inconvenience,a novel generalization distribution table concept lattice(GDTCL) default rule discovery model was proposed,which was combined the benefits generalization distribution table(GDT)and concept lattice(CL) theory.The approach introduced the GDT technique to calculate subset of condition attributes,is an efficient method to solve the NP-problem of rough sets theory to discovery ru... |
