| 摘 要： | 在常用的计算时间阈值识别方法的基础上,提出了一种改进的基于 URL 页面类型、页面信息量和访问时间的平均阈值识别方法.针对不同的页面类型采用不同的阈值计算方法设置时间阈值,相对于已有的对所有用户页面使用单一的先验阈值和现有动态阈值计算,该方法能够更真实地反映用户会话的情况,且识别的准确率有了较大提高.

| Abstract: | Based on the commonly used method of computing time threshold method,an improved method of session identification which based on page type,page size,visiting time is brought forward.For different page types,different threshold calculation methods are used to set the time threshold.Relative to the existing use of a single priori threshold and current dynamic threshold computing method,the method can give more realistic reflection of the session situation and the accuracy has been greatly improved. |
