Abstract: In order to resolve the mining problem of the quantitative association rule, a concept of similar attributes set matrix is proposed. In the meanwhile, a new algorithm of the quantitative association rules(Qarmasm) is proposed based on this concept. The algorithm does not need to expend attribution of tradition, and it has higher efficiency of reducing. It can produce pre-frequent itemsets and get support directly, and find frequent itemsets efficiently. The paper analyzes the complexity of algorithm and validates its validity, gives the application and contrast to indicate that this algorithm is much better than the traditional algorithm.

Key words: similar attributes set matrix, frequent pattern, association rule, data mining
