Abstract: Business process modeling plays an important role in business process management.Traditional artificial modeling method is time-consuming with instable accuracy.The process recommendation technique can improve the intelligence and efficiency of process modeling.However,most of the existing recommendation-based process modeling methods focus on the process structure and neglect the behavior.In fact,two process models with the same structure may contain different behaviors.Thus,a recommendation-based process modeling method was proposed in terms of behavior,which provided a set of related task nodes to users and helped them efficiently model a process.The reference process being modeled and all process models in the repository were transformed into the process structure trees.Then,the independent paths that represented the behaviors of these process models were extracted.The similarities of independent paths between the reference process and each process model in the repository were calculated,the top k independent paths in the repository were selected and the next nodes of the current nodes in these independent paths were recommended.If the independent paths in the repository were same with the independent path of reference process,their respect path weight were calculated and the larger one was preferentially recommended.Based on the proposed method,a visual prototype system that allowed users to visually model a process was implemented based on the recommendation results.The proposed method was compared with the existing method in terms of accuracy and efficiency,and the experiment results showed that the proposed method could meet the practical applications.
