Abstract
Data preprocessing is a critical step in Web Usage Mining.The results of data preprocessing are relevant to its subse- quent steps,such as transaction identification,path analysis,association rule mining and sequential pattern mining.An algo- rithm of data preprocessing called"USIA"is presented and experimentally proved to be high efficiency.It can identify users and dialogs exactly.
