Weighted association rules are to research on association rule mining expansion. It is aimed at users of different project importance of different database mining, to help users find interesting association rules, but also does not produce too many useless rules. The most important process of weighted association rules mining is weighted to generate frequent item sets. Unidirectional FP- tree node entry's serial number marking and recording the support count. Item number by the support from big is to small order determination. The paper presents the research of a novel weighted association rules algorithm based on unidirectional FP tree. Implementation results show that the algorithm unidirectional FP running efficiency is relatively high.
