摘要:

发现重要项集是数据采掘的基本问题之一。最近的研究表明,约束编程是解决数据采掘任务的一种灵活的方法。使用约束编程方法,我们可以很容易地表达和有效地回答用户对项目的约束查询。然而,在许多实际情况下,查询也可能表达用户对数据集本身的约束。例如,请求数据集特定部分中的特定项集。本文提出了一个通用的约束规划模型,能够处理任何类型的查询的项目或数据集的项目集挖掘。

英文摘要:

Discovering significant itemsets is one of the fundamental problems in data mining. It has recently been shown that constraint programming is a flexible way to tackle data mining tasks. With a constraint programming approach, we can easily express and efficiently answer queries with users constraints on items. However, in many practical cases it is possible that queries also express users constraints on the dataset itself. For instance, asking for a particular itemset in a particular part of the dataset. This paper presents a general constraint programming model able to handle any kind of query on the items or the dataset for itemset mining.
