基于接口变迁的交互流程模型挖掘方法

摘要

流程模型挖掘是基于系统运行记录下的事件日志来还原特征对应流程模型的技术.目前已有的挖掘方法多是基于由系统分解出的不同模块之间交互频繁且模块包含特征较少的场景.在挖掘包含较多特征、交互不频繁的流程模型方面,目前的方法存在一定的局限性.鉴于此,文中提出了基于接口变迁的交互流程模型挖掘方法.首先,利用现有的挖掘方法来挖掘模块内部的特征序,确定初始模块网;其次,遍历事件日志以查找疑似接口变迁;然后,通过挖掘特征网来确定接口变迁,并对接口变迁增加接口库所;最后,基于开放Petri网,利用合成网的观点将交互模块合成为一个完善的流程模型Petri网.通过实例分析,验证了该挖掘方法的有效性.%Process model mining is a technology based on the event logs recorded by running system to discover process model corresponding to features.At present,most of the mining methods are based on the frequent interaction between different modules which are decomposed by the system,and there are a few features within modules.There are some limitations of the current process mining methods in the aspect of mining process model which includes multiple features and infrequent interaction.This paper provided an interaction models process mining method based on interface transi-tions.Firstly,the order of features within modules is discovered using existing methods of mining to find the initial module nets.Secondly,the event log is traversed to search the suspect interface transitions.Then,the interface transition is determined by the mining of the feature net,and the interface place is added to it.Finally,based on the view of open Petri net,the interactive modules are synthesized into a complete process model Petri net.The analysis of instance is used to verify the effectiveness of the mining method.
