摘要
序贯模式是时间相关数据库中存在的一种十分有用的知识模式,其发掘方法的研究有着十分重要的意义。本文给出了一种挖掘数据库中序贯模式的算法,通过认真地研究了挖掘过程中的中间及结果数据的存储结构,从而大大地减少了对数据库的扫描遍数,提高了算法的效率。
The sequential pattern is a very useful knowledge one in time related databases, and it is very important to find out high efficient algorithm of mining it. This paper presents a novel algorithm of mining sequential patterns in database. The data structure used during the mining is expressly probed into to reduce the database scan times and increase the efficiency of the mining algorithm.
