- PublikationDevelopment of fake news model using machine learning through natural language processing(World Academy of Science, Engineering and Technology, 2020) Hinkelmann, Knut [in: International Journal of Computer and Information Engineering]Fake news detection research is still in the early stage as this is a relatively new phenomenon in the interest raised by society. Machine learning helps to solve complex problems and to build AI systems nowadays and especially in those cases where we have tacit knowledge or the knowledge that is not known. We used machine learning algorithms and for identification of fake news; we applied three classifiers; Passive Aggressive, Naïve Bayes, and Support Vector Machine. Simple classification is not completely correct in fake news detection because classification methods are not specialized for fake news. With the integration of machine learning and text-based processing, we can detect fake news and build classifiers that can classify the news data. Text classification mainly focuses on extracting various features of text and after that incorporating those features into classification. The big challenge in this area is the lack of an efficient way to differentiate between fake and non-fake due to the unavailability of corpora. We applied three different machine learning classifiers on two publicly available datasets. Experimental analysis based on the existing dataset indicates a very encouraging and improved performance.01B - Beitrag in Magazin oder Zeitung
- PublikationAgile visualization in design thinking(Springer, 2020) Hinkelmann, Knut [in: New trends in business information systems and technology]This chapter presents an agile visualization approach that supports one of the most widespread innovation processes: Design Thinking. The approach integrates the pre-defined graphical elements of SAP Scenes to sketch digital scenes for storyboards. Unforeseen scenarios can be created by accommodating new graphical elements and related domain-specific aspects on-the-fly. This fosters problem understanding and ideation, which otherwise would be hindered by the lack of elements. The symbolic artificial intelligence (AI)-based approach ensures the machineinterpretability of the sketched scenes. In turn, the plausibility check of the scenes is automated to help designers creating meaningful storyboards. The plausibility check includes the use of a domain ontology, which is supplied with semantic constraints. The approach is implemented in the prototype AOAME4Scenes, which is used for evaluation.04A - Beitrag Sammelband

- PublikationOntology-based visualization for business model design(Springer, 2020) Hinkelmann, Knut [in: The Practice of Enterprise Modeling. 13th IFIP Working Conference, PoEM 2020, Riga, Latvia, November 25-27, 2020. Proceedings]The goal of this paper is to demonstrate the feasibility of combining visualization and reasoning for business model design by combining the machine-interpretability of ontologies with a further development of the widely accepted business modeling tool, the Business Model Canvas (BMC). Since ontologies are a machine-interpretable representation of enterprise knowledge and thus, not very adequate for human interpretation, we present a tool that combines the graphical and human interpretable representation of BMC with a business model ontology. The tool connects a business model with reusable data and interoperability to other intelligent business information systems so that additional functionalities are made possible, such as a comparison between business models. This research follows the design science strategy with a qualitative approach by applying literature research, expert interviews, and desk research. The developed AOAME4BMC tool consists of the frontend, a graphical web-based representation of an enhanced BMC, a web service for the data exchange with the backend, and a speci c ontology for the machine-interpretable representation of a business model. The results suggest that the developed tool AOAME4BMC supports the suitability of an ontology-based representation for business model design.04B - Beitrag Konferenzschrift
- PublikationArchiMEO: A standardized enterprise ontology based on the ArchiMate conceptual model(2020) Hinkelmann, Knut [in: Proceedings of the 8th International Conference on Model-Driven Engineering and Software Development]Many enterprises face the increasing challenge of sharing and exchanging data from multiple heterogeneous sources. Enterprise Ontologies can be used to effectively address such challenge. In this paper, we present an Enterprise Ontology called ArchiMEO, which is based on an ontological representation of the ArchiMate standard for modeling Enterprise Architectures. ArchiMEO has been extended to cover various application domains such as supply risk management, experience management, workplace learning and business process as a service. Such extensions have successfully proven that our Enterprise Ontology is beneficial for enterprise applications integration purposes.04B - Beitrag Konferenzschrift

- PublikationDigital Maturity Model - How companies can achieve sustainable competitiveness in the future and the digital age(edition gesowip, 2019) Fluri, Jasmin; Schwaferts, Dino; Verkuil, Arie Hans; Hinkelmann, Knut; Aeschbacher, Marc [in: Digitalisierung und andere Innovationsformen im Management]For companies to be sustainably successful in the digital age, there are certain preconditions they must fulfill to be able to react to customer expectations and offer appropriate products or services competitively. This ability to proactively provide proper products or services within an adequate period is called Digital Maturity. To reach Dig-ital Maturity, companies must establish four preconditions: Customer Knowledge, Strategic Management, Technical Capability, and Cultural Agility. Those preconditions are called pillars of Digital Maturity. This chapter explains, why Digital Maturity concerns the whole company and requires different prerequisites on the leadership- as well as on the technical-, organizational, and cultural side of a company. The Digital Maturity assessment of the University of Applied Sciences and Arts Northwestern Switzerland is introduced and explains how to set up and incrementally perform a Digital Maturity assessment inside a company to continuously improve the companies’ Digital Maturity.04A - Beitrag Sammelband
- PublikationDigital business development & portfolio. How to develop and manage digital business streams(edition gesowip, 2019) Grüner, Peter; Schwaferts, Dino; Studer, David; Wild, Simon; Verkuil, Arie Hans; Hinkelmann, Knut; Aeschbacher, Marc [in: Digitalisierung und andere Innovationsformen im Management. Aktuelle Perspektiven auf die digitale Transformation von Unternehmen und Lebenswelten]“The internet is like a wave. You either learn to swim with it or you will sink.” (Bill Gates). With this quote, Gates already pointed to the development of a digital economy, a completely new economic model based on information technology, where we now live. On the one hand, these new opportunities in information and communication technology (ICT) are changing the way companies have to operate. On the other hand, they are also changing customer expectations in a rapid and continuous manner that transforms them into fast moving targets. Therefore, legacy as well as non-legacy businesses have to rethink their business models, predict customer expectations and have to focus on customer centricity as well as on their own uniqueness on the market. In other words, organizations have to be very agile: they have to enable flexibility in their business models and diversify their risks in a well-managed way to remain competitive in such a dynamic environment. For these reasons, business model innovation is a crucial ability to manifest one’s own inimitability. Furthermore, business model innovation enables companies to search for new business logics and groundbreaking ways to create and capture value for its stakeholders. Nevertheless, such an innovative approach is risky, primarily due to its uncertainty of commercialization. Therefore, companies should not replace existing business models, but assess them with regard to the risk of a digital disruption and start with potential new business models next. This also requires changes in the organizational structure and asks for new methods to manage such a complex system of various business model development directions in a well-controlled way. One approach to cope with this challenge could be the digital business portfolio derived at the University of Applied Sciences and Arts Northwestern Switzerland (FHNW).04A - Beitrag Sammelband
- PublikationDigital ecosystem. How companies can achieve a sustainable competitiveness in the future and the digital age(edition gesowip, 2019) Grieder, Hermann; Schwaferts, Dino; Verkuil, Arie Hans; Hinkelmann, Knut; Aeschbacher, Marc [in: Digitalisierung und andere Innovationsformen im Management. Aktuelle Perspektiven auf die digitale Transformation von Unternehmen und Lebenswelten]Companies today are still highly influenced by the management theories of the indus-trial age. To be successful in the future companies need to become part of digital eco-systems where partners and customers will be co-creators. Customers and employees’ expectations are changing, and managers need to re-evaluate traditional management methods to enable companies to successfully transition into the digital era. During the transition, we will see a change from sociotechnical systems to transitional constructs that enable co-creation and collaboration. Digital Arenas will allow companies to create value outside of their industry by collaborating with other companies through APIs; this will give rise to new business models everywhere.04A - Beitrag Sammelband
