| 摘 要： | 大多序列模式挖掘算法在处理呈指数增长的模式时性能有限，而且当输入的数据集很大时，因为主存限制将使其变成不可解的。本文提出基于分区的序列模式挖掘算法，克服了主存限制的缺点，并通过增量聚类方法对数据预处理，得到更合理的分区以提高整体性能。

| Abstract: | Most methods show limited performance due to the exponential number of growing patterns. Moreover when the input data set is very large, it is unsolvable because of main memory limitation. This paper shows a partition-based approach to overcome this drawback, and uses pre-processing method based on incremental clustering to get seemly partitions. |
