Research of Implicit Problems in Workflow Mining

Abstract

This paper analyzes the problems of implicit places and implicit transitions.In view of the shortage of a algoritm to resolve the implicit problems,a+~* algorithm is presented.In this algorithm,the implicit tasks are marked in another style,the model are constructed by the dependency of the tasks.It uses CPN Tools to general log files and mines the logs by ProM and a+~* algorithm.The simulation results validate the efficiency of the algorithm.
