摘要
利用属性间的相互关系对关联分析进行剪裁 .针对关联分析会得到过多的属性间关系这一问题 ,分析了影响关联分析结果的诸多因素 ,提出了对包容关系、递推关系以及互逆关系的剪裁算法 .经实例运算表明 ,新算法能有效地剪裁关联分析所得到的结果关系集合 .在此基础上 ,对几种关系剪裁算法进行了比较和讨论 ,并提出了一些改进设想 .
Pruning association rules by using the relationship between attributes were setup. Aiming at the problem of too many association rules, factors affecting the result of association analysis were analyzed and some new methods of pruning association rules were introduced. A certain university's student database was taken as an example to evaluate the performance of these methods. Result shows that these methods can prune the result set of association analysis effectively and some comparisons and discussions between these methods were made. Suggestions for further improvement were introduced lately.
