In spatial association transverse mining,aiming to that presented these mining algorithms based on spatial transaction didn\'t quickly mine spatial cross-layer association,an algorithm of spatial cross-layer association rules mining is proposed,which is suitable for extracting spatial cross-layer association rules in spatial association transverse mining.
在空间关联横向挖掘中,针对现有基于空间事务的挖掘算法不能快速地挖掘空间跨层关系,提出一种空间跨层关联规则挖掘算法,其适合在空间关联横向挖掘中提取空间跨层关联规则;该算法将空间事务的跨层关系转换为整数,采用自顶向下搜索策略,按非频繁项对应的属性位数递减的方式产生候选频繁项,有效地提高挖掘效率;在提取空间跨层关联规则时,实验证明它是快速的。
