New Algorithm for Mining Workflow Frequent Closet Pattern
一种新的工作流频繁闭合模式挖掘算法研究

To improve the accuracy of workflow frequent patterns, we proposed a new algorithm for mining frequent closed pattern. First, we extended the definition of the dependence Matrix, which includes direct dependency and over- lapping relationship among activities from the work flow logs. Second, we extended the CHARM algorithm to mine all closed frequent patterns over the dependence matrix Finally, the workflow frequent patterns were generated by discar- ding non-frequent patterns. The algorithm has advantages in dealing with the interleaving relations among activities and workflow models with both serial or parallel relations.
