In the paper, we propose a fast, efficiency increment renewal algorithm （MLARU） for mining multilevel association rule. It＇s basic idea is to be construct the concept level tree by the database and the Web log,accords to express the itemsets support of the crossover level by application the interval support, and gives to mining multilevel association rule by application the method of the level tree pruning and the increment renewal. The simulation result shows the high optimization efficiency of this algorithm and gives to th...
