In this contribution, we devise an ontology-based assistant for semi-formal process modeling. The assistant is intended to support the modeler in creating high quality process models with less time and effort by reusing knowledge captured in a reference ontology. At first, we derive functionalities for such an assistant. We then show how the approach can be implemented and integrated into an existing modeling tool. Finally, we describe an experimental evaluation of the approach.enText/Conference Paper1617-5468
