摘要: 在移动计算中与移动用户位置相关的移动对象位置管理服务以及基于位置的移动增值服务等都离不开移动用户移动模式的挖掘。该文利用用户的移动日志,通过非二频繁项集把整个日志切割为一系列的子序列,然后把子序列分别归入频繁子序列和非频繁子序列这两个箱中,再分别对其进行合并和拆分处理,寻找最大频繁项集,即移动用户的最大移动模式。

Abstract: The management of mobile object location and the increasing service based on location in mobile computing both need the mining of user moving patterns. This paper uses the mobile log, and separates it into a series of sub-sequences through the non-frequent items, then sets those sequences in two boxes and disposes them by merging and splitting respectively to find maximal sequences, namely user moving patterns.
