Abstract: A quantitative method for mining positive and negative association rules is proposed. The whole structure of minin system is introduced, including support degree and confidence degree. By increasing the degree of contrast influence, this structure is optimized, which promotes the mining efficiency of interesting knowledge. Simulation experimental results show this method can eliminate some invalid association rules, and make up for the demerits of traditional ones. It has the value of application.

Key words: data mining, negative association rules, contrast influence
