| Abstract: | This paper provides a method of obtaining frequent itemset from association rules based on Hash_-tree quick research itemset. The method of Hash_-tree which is used to array the candidate set of itemsets and obtain their times observably increase speed of realizing algorithm, and achieves great effect in practice. |
