摘要 数据预处理是Web使用挖掘的一个关键环节,数据预处理的结果直接影响到后续步骤,如事务识别、路径分析、关联规则挖掘和序列模式挖掘的效果。提出了一种精确识别用户和会话的数据预处理算法(USIA),并且用实验证明它是高效的。 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.
