Abstract: Aiming at the contradiction between flexibility and support of process in workflow management system,an autonomous dynamic construction method of processes based on user's personalized characteristics and preferences was put forward.In this method,the service-oriented collaborative filtering method was extended to a more complex,process-oriented similarity model of implemented instances.According to the users'tracks and the contexts of processes'instances,the model could give current user recommendations during execution of process so that the dynamic autonomous construction of whole process was realized.Without the pre-modeling,the constraint-based workflow management system was improved by this method.The balance between flexibility and support of workflow management system was achieved,and the qualities of the overall process as well as the user's experience were improved.

Key words: workflow management system, preference, dynamic autonomous construction of personalized process, collaborative filtering
