Abstract

The field of process model similarity matching is well examined for imperative process models like BPMN models, Petri nets, or EPCs where a lot of different measuring techniques exist. For the recently upcoming declarative process models, generally providing more flexibility than imperative models, however, there is a lack of comparison methods. Along with their advantage of providing more flexibility, declarative process models have a disadvantage in comprehending the models, especially the models' behavior. To overcome this problem, a comparison of imperative and declarative models is reasonable to check whether the declarative model represents a desired behavior which is easier to express and validate in an imperative notation. The work at hand provides a method based on flow dependencies, abstracting from the modeling type, for comparing two process models. It uses not only information about control-flow, but also data-based dependencies between process activities.
