Publikation Domain-specific conceptual modeling. Concepts, methods and ADOxx tools(Springer, 2022) Karagiannis, Dimitris; Lee, Moonkun; Hinkelmann, Knut; Utz, WilfridThis book demonstrates the significance of domain-specific conceptual modeling through new research and development approaches that are manifested in each of the chapters. They include novel modelling methods and tools that emphasize the recent results accomplished and their adequacy to assess specific aspects of a domain.03 - SammelbandPublikation An agile and ontology-aided modeling environment(Springer, 2018) Laurenzi, Emanuele; Hinkelmann, Knut; van der Merwe, Alta; Buchmann, Robert Andrei; Karagiannis, Dimitris; Kirikova, MariteEnterprise knowledge is currently subject to ever-changing, complex and domain-specific modeling requirements. Assimilating these requirements in modeling languages brings the benefits associated to both domain-specific modeling languages (DSMLs) and a baseline of well-established concepts. However, there are two problems that hamper the speed and efficiency of this activity: (1) the separation between the two key expertise: language engineering and domain knowledge, and (2) the sequential modeling language engineering life-cycles. In this work, we tackle these two challenges by introducing an Agile and Ontology-Aided approach implemented in our Modeling Environment - the AOAME. The approach seamlessly integrates meta-modeling and modeling in the same modeling environment, thus cooperation between language engineers and domain experts is fostered. Sequential engineering phases are avoided as the adaptation of the language is done on-the-fly. To this end, a modeling language is grounded with an ontology language providing a clear, unambiguous and machine-interpretable semantics. Mechanisms implemented in the AOAME ensure the propagation of changes from the modeling environment to the graph-based database containing the ontology.04B - Beitrag KonferenzschriftPublikation A new paradigm for the continuous alignment of business and IT: combining enterprise architecture modelling and enterprise ontology(Elsevier, 2016) Hinkelmann, Knut; Gerber, Aurona; Karagiannis, Dimitris; Thönssen, Barbara; van der Merwe, Alta; Woitsch, RobertThe paper deals with Next Generation Enterprise Information Systems in the context of Enterprise Engineering. The continuous alignment of business and IT in a rapidly changing environment is a grand challenge for today’s enterprises. The ability to react timeously to continuous and unexpected change is called agility and is an essential quality of the modern enterprise. Being agile has consequences for the engineering of enterprises and enterprise information systems. In this paper a new paradigm for next generation enterprise information systems is proposed, which shifts the development approach of model-driven engineering to continuous alignment of business and IT for the agile enterprise. It is based on a metamodelling approach, which supports both human-interpretable graphical enterprise architecture and machine-interpretable enterprise ontologies. Furthermore, next generation enterprise information systems are described, which embed modelling tools and algorithms for model analysis.01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Process-based knowledge management: Experiences with two projects(06.06.2002) Telesko, Rainer; Karagiannis, Dimitris04B - Beitrag KonferenzschriftPublikation Business an IT alignment: the IT-Socket(Springer, 2009) Woitsch, Robert; Karagiannis, Dimitris; Plexousakis, Dimitris; Hinkelmann, Knut01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Business and IT alignment: the IT-Socket(Springer, 2009) Woitsch, Robert; Karagiannis, Dimitris; Plexousakis, Dimitris; Hinkelmann, Knut01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Knowledge Selection with Neural Networks(10.07.1999) Telesko, Rainer; Karagiannis, Dimitris04B - Beitrag KonferenzschriftPublikation Intelligente Virenerkennung und -klassifikation: Das (V)-SECURENET-Projekt(vdf Hochschulverlag, 1996) Karagiannis, Dimitris; Telesko, Rainer04B - Beitrag KonferenzschriftPublikation Knowledge management concepts and tools: The PROMOTE project(Shaker, 2001) Telesko, Rainer; Karagiannis, Dimitris; Woitsch, Robert; Gronau, Norbert04A - Beitrag SammelbandPublikation Realising process-oriented knowledge management: Experience gained in the PROMOTE-project(Universität Dortmund, 10.10.2001) Telesko, Rainer; Karagiannis, Dimitris; Molitor, Ralf04B - Beitrag Konferenzschrift
