Abstract:

On the basis of the framework of ontologybased abstraction model, a method of workflow perceptionmodeling was proposed. Knowledge of constructing workflow abstraction model of a particular field can be captured via perceiving the practical workflow running in the field. The knowledge provides the mechanism of sharing and reuse for task of workflow model design, which is used to construct workflow abstraction model so as to wholly (or partly) realize the automation of the flow in the field. In this paper, activity ontology class and activity relationship ontology class are defined and the process of dynamically generating and extending them is formally described. Moreover, the process of workflow abstraction modeling based on framework of ontologybased abstraction modeling, is also given.

Key words: workflow abstraction modeling, workflow perception, ontology class, activity ontology class, activity relationship ontology class
