Abstract:  

Abstract:  Association rules mining is an important method in data mining. Combined with traditional algorithm based on support and confidence limit, the paper brings forward a weightbased method to mining association rules and gives some different methods to calculate attribute’s weight. The difference of these methods is compared at the end of this paper. We give an example to show our method is effective.
