摘　　要：为了抽取工作流过程变更的有效信息,基于变更事务组织的变更日志,讨论了复杂变更事务中主变更(primary changing)操作和伴随变更(concomitant changing)操作的关系问题,并在变更事务中主变更确定情况下对伴随变更操作进行修正,以消除主变更操作相互抵消后,其伴随变更带来的隐藏影响。在此基础上提出了去除变更日志中不相关信息和噪声的具体方法。最后根据提出的算法求解了一个包含复杂变更事务的变更日志清洗问题,并搭建实验原型,以一个实验说明了该方法的正确性和有效性。In order to extract valid information of workflow process changes,based on change transactions,the relationship between primary changing operations and its concomitant changing operations was discussed.According to the primary changing operations of a change transaction,revised its concomitant changes to eliminate the hidden effect caused by counteract of primary changing operations.Whereafter,proposed details of purge noise from change logs.Finally,this paper obtained an issue of purging change log with co...
