In this paper, we introduce and formally specify an event-based communication concept for business process modelling, constituted by event trigger properties and event pools. We claim that this concept provides a much bigger scope for modelling communication than currently available concepts, particularly when actor and user interaction modelling are included.enText/Conference Paper1617-5468
