工作流日志中的工作流模式图挖掘技术研究

Research of workflow schema mining from workflow logs

工作流挖掘技术能够从系统的执行日志中构建出过程,大部分过程挖掘方法都使用了一种图形化的方式来表示模型,也就是控制流图。讨论了工作流模式图挖掘,它实际上是工作流挖掘的一种扩展;对其中所涉及的问题进行了剖析,并介绍了一种模式图挖掘算法。

Workflow mining can construct process models from logs of past executions of system. Most of approaches for it assume a graphical representation of the model, namely control flow graph. Workflow schema mining extends workflow mining in nature, This paper discussed the techniques of schema mining, analyzed the challenging problems involved in it and introduced an algorithm of schema mining.
