Data preprocessing method of Web log mining is studied.Frame pages filtering and overtime threshold value seting are analyzed.The improved method based on induction of decision tree(ID3) algorithm and threshold value dynamic amendment algorithm is proposed.This method deals with information loss by Frame pages filtering and threshold value fixing.Transaction session identification ability is also enchanced.The experiment about this method shows that this method is efficient in improving accuracy of mining result.
