【摘要】 该文主要对移动日志数据库不断更新的问题,提出了增量挖掘的方法,挖掘用户的移动模式。其主要思想是利用原来数据库的挖掘结果,通过将候选模式分成两部分,并适当剪枝,计算在原来数据库和新增数据库中的支持度得到频繁模式,从而提高挖掘效率。更多还原

【Abstract】 An incremental mining technique is proposed in order to solve the problem of frequent updating of moving log database and mine the user mobility patterns.The main idea is to utilize the results acquired during an earlier mining process to cut down on the cost of finding new patterns in the updated database.The candidates are partitioned into two sets and separately count the supports of candidates with respect to the former database and the incremented database after proper pruning.更多还原
