- KonferenzbeitragAutomatisierte Generierung fachlicher Prozessmodelle basierend auf natürlichsprachlichen Prozessbeschreibungen(Modellierung 2024, 2024) von Olberg, Pauline; Strey, LukasDie manuelle Erstellung von Prozessmodellen ist eine gängige Tätigkeit im Rahmen der Softwareentwicklung. Die Erstellung der Modelle stellt allerdings eine zeitintensive Aufgabe für IT-Fachkräfte dar. Mit dem Ziel, die Fachkräfte zu entlasten, stellen wir die Methode NL2BPMN und einen Prototyp vor, durch welche natürlichsprachliche sowie fachspezifische Prozessbeschreibungen automatisiert in BPMN-Prozessmodelle transformiert werden können. Die Methode basiert auf Natural Language Processing (NLP) und bedient sich unter anderem dem Part-of-Speech-Tagging sowie dem Dependency Parsing. Ein Bestandteil der Methode ist die Verwendung einer Fachbegriffe-Liste als zusätzlicher Input neben Prozessbeschreibungen, um Fachbegriffe, die aus mehreren Wörtern bestehen, als zusammengehörige Begriffe zu verarbeiten. Ein Vergleich von automatisiert generierten Modellen mit manuell erstellten Modellen zeigt Erfolgsquoten von über 90 \% in allen Bewertungskategorien, sofern eine Fachbegriffe-Liste verwendet wird.
- KonferenzbeitragTransforming Object-Centric Process Models into BPMN 2.0 Models in the PHILharmonicFlows Framework(Modellierung 2024, 2024) Breitmayer, Marius; Arnold, Lisa; Pejic, Marko; Reichert, ManfredBusiness processes can be modeled using a plethora of different paradigms including activity-centric (e.g., imperative, declarative), and data-centric processes. The former focus on the process activities to be executed as well as their execution order and constraints, whereas the latter deal with the data required to progress during process execution. Both representations, however, allow describing the same process, but from different viewpoints. Consequently, a transformation between process representations based on the different paradigms yields promising perspectives for enabling a holistic view on both the behavior and the data perspective of a process and fosters a common understanding of different paradigms. This paper presents an approach for transforming object-centric processes (i.e., object lifecycle processes and their interactions) into corresponding activity-centric representations modeled in terms of BPMN 2.0. We present seven transformation rules for mapping an object- to an activity-centric process, illustrated along a running example. We evaluate the approach based on a proof-of-concept implementation that can automatically perform the necessary transformations and has been applied in multiple scenarios. Overall, our approach for transforming object-centric processes into BPMN 2.0 models provides new insights into the relationship between the two paradigms and enables a more flexible and effective way of modeling business processes in general.
- KonferenzbeitragProcess Mining for Unstructured Data: Challenges and Research Directions(Modellierung 2024, 2024) Koschmider, Agnes; Aleknonytė-Resch, Milda; Fonger, Frederik; Imenkamp, Christian; Lepsien, Arvid; Apaydin, Kaan; Janssen, Dominik; Langhammer, Dominic; Ziolkowski, Tobias; Zisgen, YorckThe application of process mining for unstructured data might significantly elevate novel insights into disciplines where unstructured data is a common data format. To efficiently analyze unstructured data by process mining and to convey confidence into the analysis result, requires bridging multiple challenges. The purpose of this paper is to discuss these challenges, present initial solutions and describe future research directions. We hope that this article lays the foundations for future collaboration on this topic.
- KonferenzbeitragAdvancing Virtual Coaching in Healthcare: Towards A Unified Terminology and Reference Model(Modellierung 2024, 2024) Gißke, Carola; Weiman, Thure Georg; Schlieter, HannesVirtual coaching applications, designed to facilitate behavior change through adaptive coaching activities, hold promise for personalized interventions, particularly in healthcare. While existing literature explores various aspects of virtual coaches (VCs), there is a lack of comprehensive conceptual analysis, and inconsistent terminology further complicates their understanding. The present paper aims to demonstrate the ongoing work on systematically categorizing and describing the components of VCs and, thereby, creating a reference model reusable for different contexts. Based on a systematic literature review, concepts related to VC interventions will be derived, categorized, and linked to each other, forming a unified framework that could simplify the process of designing VCs and provide the foundation for dedicated building tools in terms of low/no-code platforms. Moreover, the work contributes with a consolidated terminology, and the proposed model may also be used to identify underexplored research areas, enhancing research opportunities in the field.
- KonferenzbeitragDigital Transformation through Conceptual Modeling: The NEMO Summer School Use Case(Modellierung 2024, 2024) Völz, Alexander; Vaidian, IuliaIn the digital age, achieving a balance between human creative thinking and technology capabilities is crucial. Recognizing the potential of such collaborations, OMiLAB (Open Model Initiative Laboratory) developed a conceptual framework for establishing experimental innovation spaces in which skills to advance human-machine interaction can be taught and applied. The resulting Digital Innovation Environment incorporates both business and engineering perspectives, emphasizing the importance of interdisciplinary settings. Conceptual models and Digital Twins play a pivotal role within the environment, seamlessly bridging business strategies with cyber-physical systems. This paper offers a comprehensive understanding of the OMiLAB network, highlighting its alignment with the principles of a Community of Practice and emphasizing the knowledge exchange, exemplified by the NEMO Summer School Series. We present insights, best practices, and educational paradigms vital for navigating the digital transformation landscape.
- KonferenzbeitragSemantic Models for Trustworthy Systems: A Hybrid Intelligence Augmentation Program(Modellierung 2024, 2024) Guizzardi, GiancarloCyber-human systems are formed by the coordinated interaction of human and computational components. In this talk, I will argue that these systems can only be designed as trustworthy systems if the interoperation between their components is meaning preserving. For that, we need to take the challenge of semantic interoperability between these components very seriously. I will discuss a notion of trustworthy semantic models and defend its essential role in addressing this challenge. Finally, I will advocate that engineering and evolving these semantic models as well as the languages in which they are produced require a hybrid intelligence augmentation program resting on a combination of techniques including formal ontology, logical representation and reasoning, crowdsourced validation, and automated approaches to mining and learning.
- KonferenzbeitragBeobachtungen und Einsichten zu Repositorys von BPMN-Modellen(Modellierung 2024, 2024) Laue, Ralf; Läuter, MartinBei der empirischen Untersuchung der Praxis der Geschäftsprozessmodellierung ist man auf eine umfangreiche, vielfältige und gleichzeitig zur Aufgabenstellung passende Datenbasis angewiesen. Wir untersuchen eine Reihe öffentlich zugänglicher Modellrepositorys mit BPMN-Modellen, die in den vergangenen Jahren entstanden sind. Wir weisen auf Eigenarten der Repositorys hin, die die Verarbeitung der Daten erschweren und die Datenqualität beeinträchtigen. Besonders diskutiert wird das in bisherigen Arbeiten nicht betrachtete Phänomen von de facto inhaltsgleichen Modellen in bei bitweisem Vergleich verschiedenen Dateien. Wir diskutieren die Auswirkung solcher Duplikate und schlagen eine der jeweiligen Aufgabenstellung angepasste Filterung vor. Wir begründen, warum dieses Vorgehen insbesondere bei Ansätzen zum maschinellen Lernen beachtet werden sollte. Wir stellen fest, dass die empfohlenen Maßnahmen zur Sicherung der Datenqualität in aktuellen Veröffentlichungen häufig noch nicht beachtet werden, was die Aussagekraft von deren Ergebnissen in Frage stellen kann.
- KonferenzbeitragModeling Classes of Body Sensor Networks(Modellierung 2024, 2024) Carwehl, Marc; Reisig, WolfgangComputer-embedded systems frequently manifest in diverse variants, featuring slight differences in interfaces and functionalities, yet fundamentally grounded in a shared functional kernel. To address this variability, we propose to employ a schematic model of the functional kernel, from which concrete system instances are derived. This modeling methodology leverages well-established principles from predicate logic and Petri nets, augmented with the dynamic extensions provided by the \textsc{Heraklit} infrastructure. As a practical case study, we explore the realm of Body Sensor Networks (BSNs), a domain increasingly pivotal in the realm of medical diagnosis. Our work showcases the versatility and adaptability of our modeling framework in the context of BSNs, offering insights into its potential applications in the broader landscape of embedded systems and beyond.
