【摘要】 传统数据挖掘算法在处理多表时,需要物理连接,存在效率不高的问题。为了解决这一问题,提出了一种多关系频繁模式挖掘算法。该算法利用元组ID传播的思想,使多表间无须物理连接,就可以直接挖掘频繁模式。实验表明,此算法具有较高的效率。更多还原

【Abstract】 While dealing with multi-relation,traditional data mining algorithms used the way of physical join.In order to solve this problem,this paper proposed a multi-relational frequent pattern mining algorithm.By taking advantage of tuple ID propagation approach,this algorithm could directly mine frequent pattern in multi-relation without physical join.Experiment demonstrates that,this algorithm has high efficiency.更多还原
