一种基于多视角数据属性的决策表Petri网挖掘方法
Approach of decision table Petri net mining method based on multi perspective data attributes
摘要
Abstract
When dealing with highly variable processes,the models may not accurately reflect the changes in the rules be-tween different decision points in the process operation,by using the existing automatic process mining techniques.From the perspective of declarative process discovery,this paper proposed a decision table Petri net mining method with visual decision rules,to realize the mapping from real event log to a declarative process decision table Petri net model.Firstly,this method formalized both the decision table Petri net model and its rule analysis decision table,and designed the static and dynamic se-mantics of the formalized decision Petri net model.Secondly,through adding extended attributes,it analyzed whether the in-ternal attributes or event attributes of the process would affect the decision.Furthermore,it generated outlier attributes with their deviation degrees of the rule analysis decision table to determine the degree of exception of the rule.Finally,it conducted experimental simulation on the basis of a set of artificial logs and practical event logs,and at the same time,it analyzed the ex-perimental results by comparing with the extant data mining technology by Petri nets.The experimental results show that the proposed method has certain advantages in representing the change of rules during the operation of the process,which can pro-vide quantitative and interpretable analysis for data flow anomaly detection.At the same time,the proposed decision table Pe-tri net mining method can integrate the decision information with the model structure together,providing a formal basis for the variability modeling of the process model.关键词
