摘要
Abstract
In the traditional association rule mining algorithm, concept hierarchy tree only provides concept hierarchy information of items, and the efficency of searching items is not high in this tree structure. This paper presents an improved multi-level association rule mining algorithm. It adds two fields in its nodes to help to accquire frequent 1-itemsets. It employs an auxiliary storage structure that is based on Hash table, which enhances efficency of searching items. Experimental result shows that mining time of the imrpoved algorithm is reduced by about 10% than before.关键词
