Business process modeling is utilized by organizations for defining and reengineering their business processes. On the other hand, ontologies are developed to strengthen shared understanding between people, organizations and software systems and ease reuse. From knowledge management point of view, both are efficient tools for creating knowledge. A tool supported transformation from process models to ontology could enhance the benefits gained from both and increase development efficiency and consistency. This study aims to demonstrate such an automated transformation on a real case. Within the study, a case study is performed to enable this transformation manually from business process models defined with eEPC language to a process ontology and an algorithm is designed and implemented for automated transformation.
