Ontology-Based Assistance for Semi-Formal Process Modeling Fellmann, Michael; Zarvic, Novica; Sudau, Annelene Jung, Reinhard; Reichert, Manfred The construction of semi-formal process models is a difficult task due to the complexity of today's business processes. 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.

Towards Auto-Suggested Process Modeling – Prototypical Development of an Auto-Suggest Component for Process Modeling Tools Clever, Nico; Holler, Justus; Shitkova, Maria; Becker, Jörg Jung, Reinhard; Reichert, Manfred Companies have accepted process modeling as a powerful instrument for business reorganization, requirements specification in software development, knowledge management and other activities. Huge amounts of processes are being modeled in organizations nowadays. However, the re-use of existing process knowledge in order to simplify the modeling process has not yet been thoroughly studied and applied. We propose an auto-suggest component for process modeling tools, which, based on existing process knowledge, “auto-suggests” the process model elements step-by-step, thus saving the modeler time and effort.

Do We Need a Standard for EPC Modelling? The State of Syntactic, Semantic and Pragmatic Quality Fellmann, Michael; Bittmann, Sebastian; Karhof, Arne; Stolze, Carl; Thomas, Oliver Jung, Reinhard; Reichert, Manfred The quality determination of business process models is a complex and demanding task. In literature, a plethora of different quality criteria can be identified and are respectively used by practitioners. The selection of quality criteria depends on the one hand on the respective preferences of the individual modeller. On the other hand, it is prescribed by the modelling language in use, as it has embodied specific criteria e.g. based on its syntax. For the widespread EPC, no comprehensive overview of existing aspects for the evaluation of an EPC model's syntactic, semantic and pragmatic quality exists. With this investigation, we present such an overview and put the identified aspects into a holistic perspective based on the identified and relevant literature.

SecSy: Synthesizing Process Event Logs Accorsi, Rafael; Stocker, Thomas Jung, Reinhard; Reichert, Manfred One difficulty at developing mechanisms for business process security monitoring and auditing is the lack of representative, controllably generated test runs to serve as an evaluation basis. This paper presents an approach and the corresponding tool support for event log synthesis. The novelty is that it considers the activity of an “attacker” able to purposefully infringe security and compliance requirements or simply manipulate the process' control and data flow, thereby creating deviations of the intended process model. The resulting logs can be readily replayed on a reference monitor, or serve as input for auditing tools based upon, e.g., process mining.
