摘要 数据挖掘由一些大型零售机构面临的"决策支持"问题所激发。对数据挖掘中的关联规则的概念和作用进行了探讨,对关联规则中寻找大项集的部分用程序流程的方式加以说明,对自连接操作的提高效率问题加以论证。通过例子说明了数据挖掘关联规则中最大项目集的子集必为最大项目集。 Data mining is motivated by the decision support problem faced by most large retail organizations.The concept and function of association rules were discussed.A application program to seek the large item set in association rules was presented.And the efficiency improving of linked-self operation was analyzed.The largest item set to be a item set was illuatrated as a exaple.
