| 摘 要： | 关联规则是数据挖掘中的重要研究内容之一。目前，已经提出了许多算法用于高效的发现大规模数据库中的关联规则，但是对关联规则的维护问题的研究工作却很少。本文对在事务数据库不变，只对最小支持度和最小可信度进行改变的情况下，如何进行关联规则的维护问题进行了探讨，并提出了一种高效的增量式更新算法。

| Abstract: | Finding association rules is an important part of data mining field .There have been many algorithms proposed for efficient discovery of association rules in large databases.However,little work has been done on maintenance of di scovered of discovered association rules.In this paper,a kind of incremental up dating algorithm is presented for such efficient maintenance problem of associat ion rules. |
