摘要
序列模式挖掘是数据挖掘中一个重要研究方向,具有广泛的应用背景.序列模式挖掘会产生大量的模式,使得人们很难利用它们.提出上、下闭序列模式的概念,并得到上、下闭序列模式及其它们之间的若干性质,为解决序列模式的数量问题提供理论基础.
Sequential pattern mining, which has broad applications, is one of key research areas in data mining. The traditional sequential patterns mining framework produces a large number of patterns which make it very difficult for people to use them. The notations of upper and lower closed sequential pattern of a sequence are presented and some properties of them are obtained, which can offer a theoretical basis for solving the problem of the number of sequential pattern mining.
