Association rule mining is a key issue in data mining. However the classical models ignore the difference between the transactions; and the weighted association rule mining does not work on databases with only binary attributes. In this paper, we introduce a new measure wsupport, which does not require pre-assigned weights. It takes the quality of transactions into consideration, using link-based models. A fast miming algorithm is given and a large amount of experimental results is presented.
