Purging algorithm of process change logs with complex changing transactions
一种处理复杂变更事务的过程变更日志清洗算法

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 complex change transactions, and illuminated the correctness and efficiency of this method.
