A computational literature analysis of conversational AI research with a focus on the coaching domain
(2022) Pande, Charuta; Fill, Hans-Georg; Hinkelmann, Knut; Hinkelmann, Knut; Gerber, Aurona
We conduct a computational analysis of the literature on Conversational AI. We identify the trend based on all publications until the year 2020. We then concentrate on the publications for the last five years between 2016 and 2020 to find out the top ten venues and top three journals where research on Conversational AI has been published. Further, using the Latent Dirichlet Allocation (LDA) topic modeling technique, we discover nine important topics discussed in Conversational AI literature and specifically two topics related to the area of coaching. Finally, we detect the key authors who have contributed significantly to Conversational AI research and area(s) related to coaching. We determine the key authors' areas of expertise and how the knowledge is distributed across different regions. Our findings show an increasing trend and thus, an interest in Conversational AI research, predominantly from the authors in Europe.

A cyber attack simulation for teaching cybersecurity
(2023) Scherb, Christopher; Heitz, Luc; Grimberg, Frank; Grieder, Hermann; Maurer, Marcel; Gerber, Aurona; Hinkelmann, Knut
With the rising number of cyberattacks, such as ransomware attacks and cyber espionage, educating non-cybersecurity professionals to recognize threats has become more important than ever before. However, traditional training methods, such as phishing awareness campaigns, training videos and assessments have proven to be less effective over time. Therefore, it is time to rethink the approach on how to train cyber awareness. In this paper we suggest an alternative approach -- a serious game -- to educate awareness for common cyberattacks. While many serious games for cybersecurity education exist, all follow a very similar approach: showing people the effects of a cyber attack on their own system or company network. For example, one of the main tasks in these games is to sort out phishing mails. We developed and evaluated a new type of cybersecurity game: an attack simulator, which shows the entire setting from a different perspective. Instead of sorting out phishing mails the players should write phishing mails to trick potential victims and use other forms of cyberattacks. Our game explains the intention of each attack and shows the consequences of a successful attack. This way, we hope, players will get a better understanding on how to detect cyberattacks.

A hybrid intelligent approach for the support of higher education students in literature discovery
(2022) Prater, Ryan; Laurenzi, Emanuele; Martin, Andreas; Hinkelmann, Knut; Fill, Hans-Georg; Gerber, Aurona; Lenat, Doug; Stolle, Reinhard; van Harmelen, Frank
In this paper, we present a hybrid intelligent approach that combines knowledge engineering, machine learning, and human intervention to automatically recommend literature resources relevant for a high quality of literature discovery. The primary target group that we aim to support is higher education students in their first experiences with research works. The approach builds a knowledge graph by leveraging a logistic regression algorithm which is first parameterized and then influenced by the interventions of a supervisor and a student, respectively. Both interventions allow continuous learning based on both the supervisor’s preferences (e.g. high score of H-index) and the student’s feedback to the resulting literature resources. The creation of the hybrid intelligent approach followed the Design-Science Research methodology and is instantiated in a working prototype named PaperZen. The evaluation was conducted in two complementary ways: (1) by showing how the design requirements manifest in the prototype, and (2) with an illustrative scenario in which a corpus of a research project was taken as a source of truth. A small subset from the corpus was entered into the PaperZen and Google Scholar, independently. The resulting literature resources were compared with the corpus of a research project and show that PaperZen outperforms Google Scholar

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, Robert
The 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.

A system of customer co-creation for new product development of digital products with a pilot study of the Swiss media industry
(2023) Le Cunff, Eric; Schlick, Sandra; Gerber, Aurona; Hinkelmann, Knut
In the age of digitisation, the media industry is faced with declining advertising revenues. Therefore, the focus on the development of new digital products is a key element to survive in such a fast-changing market and to increase the innovation performance. One of the most important elements thereby is the involvement of customers as co-creators in the new product development (NPD) process, so that new digital products are developed that are in demand on the market. However, the process of how companies turn external knowledge from customers into knowledge creation for generating new ideas and the development of innovative products has not been analysed. This pilot study, which presents an initial system of customer co-creation for NPD of digital products from the literature and searches for similarities and dissimilarities through an abductive qualitative data analysis from interviews with three managers in three different Swiss media companies, explores this unresolved research gap. The system of this study is based on an overarching phase model, which is derived from Application Lifecycle Management (ALM). The process anchored in it, which focuses on the customer co-creation of digital products, integrates process elements from the two user-centered approaches, namely User Centered Design (UCD) and Design Thinking (DT). The results from the interviews show that the system is largely in line with the NPD process procedures in the three media companies. It was found that customers can be involved everywhere in the NPD process, but that this is not yet implemented in practice. However, as the future ambition in media companies is to become even more customer- centric, the proposed system in this study is very promising.

Adopting AI in the banking sector - The wealth management perspective
(Springer, 2021) Wittmann, Xinhua; Lutfiju, Flutra; Gerber, Aurona; Hinkelmann, Knut
While interest in understanding the impact of Artificial Intelligence (AI) in the real world has been growing, there is limited research on what digital transformation means in the banking sector. The present paper aims to address this gap in the literature by means of a field study based on 11 interviews with wealth managers from across front, middle and back offices in a large Swiss bank. Our analyses suggest bank employees have relatively positive attitudes toward the adoption of new technologies. According to the research, the top three advantages for adopting AI in wealth management are: efficiency, enhanced clients’ experience and better customer insight. Yet, AI also brings new challenges to banking. Obstacles identified include process complexity, greater maintenance effort, and increased regulatory requirements. Still, AI is expected to change the banking model to an integrated, hybrid and leaner operation with digital processes that offer front-to-back solutions. With respect to the future of the bank workforce, hiring tech-savvy talent will be crucial. AI will be able to free bank employees from repetitive jobs for more interesting and creative tasks.

Agile management in cybersecurity
(2023) Asprion, Petra; Giovanoli, Claudio; Scherb, Christopher; Bhat, Sourabha; Gerber, Aurona; Hinkelmann, Knut
Cybersecurity management has emerged as a topic of growing importance on a global scale. Applying traditional management practices to cybersecurity is often too cumbersome and can lead to significant delays. Today's enterprises must be able to adapt to ever-evolving digital threats and act with corresponding agility and flexibility. Agile methods are well suited for projects without a defined scope, duration, tasks, and resources and has been identified as suitable for meeting the management challenges of cybersecurity teams. Based on an in-depth literature review, this study assumed that adopting an agile approach to cybersecurity helps organizations manage cybersecurity effectively. A first prototypical model was developed and evaluated which combines agile methods with cybersecurity functions - based on a recognized reference model.

Analysing barriers in the business ecosystem of European MaaS providers: an actor-network approach
(2023) Gebhart, Julian; Schlick, Sandra; Marvell, Alan; Gerber, Aurona; Hinkelmann, Knut
As new Mobility as a Service (MaaS) platforms are being established in Europe, researchers and practitioners seek evidence on the barriers experienced by the MaaS providers in their evolving business ecosystem. This paper conceptualises the MaaS business ecosystem using a Systematic Literature Review (SLR) combined with Actor- Network Theory (ANT) by constructing an actor-network of key actors. This actor- network, along with the identified MaaS business ecosystem barriers, is then used for Multiple Case Study Research, interviewing 18 European MaaS experts. The cross-case analysis revealed how MaaS providers problematise, interest, enrol and mobilise their business ecosystems. Furthermore, the paper outlines and amends key barriers in the areas of (1) technology and data, (2) social and cultural, and (3) policy and regulation. Researchers and practitioners can use the findings of this study to formulate policies, create best practices or conduct further research on the development of MaaS.

Combining machine learning with knowledge engineering to detect fake news in social networks - A survey
(2019) Ahmed, Sajjad; Hinkelmann, Knut; Corradini, Flavio; Martin, Andreas; Martin, Andreas; Hinkelmann, Knut; Gerber, Aurona; Lenat, Doug; van Harmelen, Frank
Due to extensive spread of fake news on social and news media it became an emerging research topic now a days that gained attention. In the news media and social media the information is spread highspeed but without accuracy and hence detection mechanism should be able to predict news fast enough to tackle the dissemination of fake news. It has the potential for negative impacts on individuals and society. Therefore, detecting fake news on social media is important and also a technically challenging problem these days. We knew that Machine learning is helpful for building Artificial intelligence systems based on tacit knowledge because it can help us to solve complex problems due to real word data. On the other side we knew that Knowledge engineering is helpful for representing experts knowledge which people aware of that knowledge. Due to this we proposed that integration of Machine learning and knowledge engineering can be helpful in detection of fake news. In this paper we present what is fake news, importance of fake news, overall impact of fake news on different areas, different ways to detect fake news on social media, existing detections algorithms that can help us to overcome the issue, similar application areas and at the end we proposed combination of data driven and engineered knowledge to combat fake news. We studied and compared three different modules text classifiers, stance detection applications and fact checking existing techniques that can help to detect fake news. Furthermore, we investigated the impact of fake news on society. Experimental evaluation of publically available datasets and our proposed fake news detection combination can serve better in detection of fake news.

Combining symbolic and sub-symbolic AI in the context of education and learning
(2020) Telesko, Rainer; Jüngling, Stephan; Gachnang, Phillip; Martin, Andreas; Hinkelmann, Knut; Fill, Hans-Georg; Gerber, Aurona; Lenat, Doug; Stolle, Reinhard; van Harmelen, Frank
Abstraction abilities are key to successfully mastering the Business Information Technology Programme (BIT) at the FHNW (Fachhochschule Nordwestschweiz). Object-Orientation (OO) is one example - which extensively requires analytical capabilities. For testing the OO-related capabilities a questionnaire (OO SET) for prospective and 1st year students was developed based on the Blackjack scenario. Our main target of the OO SET is to identify clusters of students which are likely to fail in the OO-related modules without a substantial amount of training. For the interpretation of the data the Kohonen Feature Map (KFM) is used which is nowadays very popular for data mining and exploratory data analysis. However, like all sub-symbolic approaches the KFM lacks to interpret and explain its results. Therefore, we plan to add - based on existing algorithms - a “postprocessing” component which generates propositional rules for the clusters and helps to improve quality management in the admission and teaching process. With such an approach we synergistically integrate symbolic and sub-symbolic artificial intelligence by building a bridge between machine learning and knowledge engineering.

Connecting Enterprise Architecture and Information Objects Using an Enterprise Ontology
(IEEE, 11/2013) Hinkelmann, Knut; Maise, Michaela; Thönssen, Barbara; van der Merwe, Alta; Gerber, Aurona; de la Harpe, Andre
In this paper we show how semantic metadata – derived from the enterprise architecture description - can improve both the exploitation of information in the operative business and the continuous alignment of information systems with the business. ArchiMEO, a formal representation of the ArchiMate framework, was applied to model selected parts of a large Swiss company, including metadata of concrete information objects stored in various applications. The evaluation of our approach clearly gave evidence that linking an enterprise ontology with operational databases is beneficiary: it provides an integrated view and management of enterprise entities spread over various data stores, represented in different ways and levels of granularity. Furthermore, because of its inference capabilities, when used as metadata encoding scheme an enterprise ontology can provide context-sensitive access to relevant information.

Design parameters of multidimensional reward system based on preference analysis of students of business information systems at the University of Applied Sciences and Arts Northwestern Switzerland
(Springer, 2021) Heimsch, Fabian; Lüthi, Erhard; Gerber, Aurona; Hinkelmann, Knut
In Switzerland, there is currently a major shortage of skilled workers in many companies and organisations. A particular bottleneck can be seen in the area of IT professions. The lack of qualified employees is a challenge for future education and training and intensifies the current competition for today's necessary and urgently sought talent in the IT sector. In this context, it will be crucial in the future how attractive and individualized compensation systems can be designed for potential employees. Needs-based compensation packages should help to attract and ultimately retain future IT professionals. The aim of this study is to measure the preferences of students of business informatics at the FHNW to analyse which elements of total rewards management are crucial for the choice of a future employer. The results will help companies optimise the total rewards system according to their needs or include those factors that can be expected to provide the best benefits for future employees. Thus, not only the total monetary value, but also the composition of financial and non-financial elements must be included in this overall consideration.The aim is to provide decision-makers in organisations with targeted information that will allow them to design optimal incentive packages to be an attractive employer for students of business informatics or potential employees in the informatics field.

Effects of Home Office on employees’ working conditions during Covid 19 crisis in Switzerland
(2021) Schulte, Volker; Steinebach, Christoph; Verkuil, Arie Hans; Gerber, Aurona; Hinkelmann, Knut
The current pandemic poses special challenges for employees. A sur-vey was conducted in April and May 2020. The impact of the switch to home office on the living circumstances, quality of life and well-being was investi-gated. 333 respondents (female 62%, male 38%) participated in this survey. The results show there during these weeks a high level of well-being in the home office. More than 70% of respondents feel comfortable in home office and would like to maintain this type of work organization after the corona crisis. Leadership is a decisive factor. Working conditions at home (suitable working environment, undisturbed work) are less decisive for well-being than good leadership by the superior. Findings show the necessity of clear communication rules, so that em-ployees are optimally integrated into the work processes and content. In addition, a high degree of personal autonomy in the home office and, at the same time, close integration into the team is important for the well-being of employees. Em-ployees would like to keep the autonomy they gained even after the crisis. How-ever, there are increasing demands due to digital leadership. Under these condi-tions, leadership means providing orientation and support from a physical dis-tance, as well as promoting the autonomy of the employee. As a negative impact of Home Office, it can be stated that employees miss regular social exchange with colleagues. In consequence, the presence at the workplace should be used as quality time for building sustainable and resilient working relationships.

Flexible workforce management. An exploratory study
(Open Education Platform, 2021) Vogel, Christoph; Schaltegger, Christina; Zölch, Martina; Gerber, Aurona; Hinkelmann, Knut
A flexible workforce is a key competitive advantage to deal with a constantly changing environment, such as order fluctuations and filling knowledge gaps due to a shortage of skilled staff. So far, only few empirical results are available on how companies successfully manage the “Flexible Workforce”. In the present exploratory study, we examine the flexible workforce practice and management in Swiss organisations using a quantitative approach. Data were collected through an online survey, in which 224 HR professionals of Swiss companies took part. The results suggest that organisations engaging in a flexible workforce benefit from outcomes like dealing with peaks in workload, filling knowledge gaps, implementation of new ideas and succession planning. The extent to which companies can benefit from the use of a flexible workforce depends, among other things, on the complexity of the tasks and organisational characteristics such as the culture of trust and the practice of knowledge management.

From managing diversity to managing opportunity
(Open Education Platform, 2021) Özdemir, Feriha; Gerber, Aurona; Hinkelmann, Knut
Companies with path-dependencies on trivial assumptions reach their limits in Society 5.0. Resilient and vital organizations need multiple reservoirs of competencies, i.e .their people’s capabilities. Furthermore, resilient organizations in hypermodernity depend on an ability to respond to rising complexity by enhancing their own inner variety and competencies. Society 5.0 is characterized by a huge amount of diversity, and is human-focused. This paper presents a human-centered approach, the Capability Approach, which is conceptualized as a developed approach to Diversity Management. This paper goes beyond the classical diversity discourse, outlining an approach to Managing Opportunities in Society 5.0 that contributes toward the SDGs and Capability Management, introducing the Capability Cycle as a process for managing opportunities for dialogue-orientated communication. An economy designed for people requires a new diversity discourse − because the right to development is an inalienable human right.

Hybrid conversational AI for intelligent tutoring systems
(Sun SITE, Informatik V, RWTH Aachen, 2021) Pande, Charuta; Witschel, Hans Friedrich; Martin, Andreas; Montecchiari, Devid; Martin, Andreas; Hinkelmann, Knut; Fill, Hans-Georg; Gerber, Aurona; Lenat, Dough; Stolle, Reinhard; Harmelen, Frank van
We present an approach to improve individual and self-regulated learning in group assignments. We focus on supporting individual reflection by providing feedback through a conversational system. Our approach leverages machine learning techniques to recognize concepts in student utterances and combines them with knowledge representation to infer the student’s understanding of an assignment’s cognitive requirements. The conversational agent conducts end-to-end conversations with the students and prompts them to reflect and improve their understanding of an assignment. The conversational agent not only triggers reflection but also encourages explanations for partial solutions.

Identification and chaining of water accounting data stakeholders
(EasyChair, 2022) Prater, Ryan; Eisenbart, Barbara; Hinkelmann, Knut; Gerber, Aurona
Purpose – Multiple water accounting techniques exist and suffer from data gaps and misaligned stakeholders which creates standardization and consolidation problems in the data of the industry. This study identifies domain-based stakeholders and defines stakeholder data relationships to improve inter-stakeholder data efficiency. Design/methodology/approach – The research design follows an inductive data collection of qualitative cross-sectional data through semi-structured expert interviews. The recorded interviews were transcribed, thematically coded, and the findings summarized. Findings – The result is an improved specificity of water accounting data stakeholders which have different data input and output requirements. Our research found that these stakeholders can be chained together based on their data relationships which enables identifying inter-stakeholder relationships and improved data efficiency. Social Implications – Water is a vital resource for humans and the United Nations Sustainable Development Goals. More precise description of stakeholders and data factors enable more efficient data flow which can improve the efficacy of terminal impact. Originality/value – The awareness of problem is refined by increasing stakeholder specificity and identifying data input/output requirements. This enables chaining of stakeholders and data to clarify stakeholder data requirements and improve data efficiency for purposes such as collaboration and policy guidance.
