During lecture time, we have our Lunchtime Seminar each Tuesday from 12.15-12.45. During this seminars, researchers of the Department or invited guest provide us with insights into their research.

29.06.2021 Biometric recognition, principles and privacy protection

The biometric comparator is the core engine of most biometric recognition systems. Its current realisations are predominantly based on machine learning. In the talk I will first review the underlying principles, which differ from those of standard machine-learning based classification, and their relation to statistical optimality. Next, I will address various security and privacy risks of the storage and processing of biometric data and discuss proposed privacy enhancing solutions.

06.07.2021 Behavioural insurance in the German Automotive Market

The automotive insurance market is undergoing fundamental changes with the advent of novel Insurance Technology (InsurTec), mobility initiatives such as autonomous vehicles, car sharing and subscription models for new cars, and the emergence of new forms of insurance such as short-term cover, pay per use and advanced analytics, which can encourage drivers to improve their driving behaviour. The traditional forms of insurance and information exchange are being augmented or replaced by... mehr

13.07.2021 NAO says hello!

Pedagogical conversational agents (CA) support formal and informal learning to help students achieve better learning outcomes by providing information, guidance or fostering reflections. Even though the extant literature suggests that pedagogical CAs can improve learning outcomes, there exists no empirical evidence of what design features drive this effect. We will briefly report on a study we conducted in this field. Furthermore, we will provide a short demonstration of a quiz... mehr

12.10.2021 Cognitive diagram understanding and task performance in system analysis and design

Speaker: Prof. Dr. Jan Mendling, Humboldt-Universität zu Berlin, Germany.

Abstract: Conceptual models play an important role in system analysis and design (SAD). In this talk, we approach diagrams in SAD from a holistic perspective. We establish the SAD process as a context for diagram usage and highlight the information needs of complex tasks. Second, we discuss in how far cognitive processing of diagrams is different... mehr

19.10.2021 Augmenting the algorithm: Emerging human-in-the-loop work configurations

Speaker: Prof. Dr. Margunn Aanestad, Department of Information Systems, University of Agder, Kristiansand, Norway.

Abstract: How do configurations of humans and algorithms evolve as firms adopt artificial intelligence (AI) capabilities, and what are the implications for work and organization? We explored these questions through a two-year long case study of an organization in the international maritime... mehr

26.10.2021 Watch Me Get Better! – Algorithm Aversion and Demonstrating the Ability to Learn

Speaker: Prof. Dr. Benedikt Berger, Department of Information Systems, the University of Münster, Germany.


Talk abstract: Owing to advancements in artificial intelligence (AI) and specifically in machine learning, information technology (IT) systems can support humans in an increasing number of tasks. Yet, previous research indicates that people often prefer support by a human to support by an IT system, even if the latter provides superior... mehr

02.11.2021 Influence diffusion in social networks: modelling, prediction, and control

Speaker: Dr. Doina Bucur, University of Twente, The Netherlands.

Abstract: Information (of influence) diffuses via links in a social network, and, even assuming that the network structure is relatively static, the size of an information cascade is hard to estimate well, both over a model and over a real social network. We cover models of information diffusion, then look at methods to predict ‘important’ nodes in the network, for example single nodes... mehr

09.11.2021 Ethics in AI: A Challenging Task

Talk title: Ethics in AI: A Challenging Task

Speaker affiliation: Ricardo Baeza-Yates, Institute for Experiential AI, Northeastern University.

Talk abstract: In the first part we cover five current specific challenges through examples: (1) discrimination (e.g., facial recognition, justice, sharing economy, language models); (2) phrenology (e.g., biometric based predictions); (3) unfair digital commerce (e.g., exposure and... mehr

16.11.2021 When do good communication models fail in global virtual teams?

Speaker: Dr. Sirkka L. Jarvenpaa, The University of Texas at Austin, USA.

Abstract: Global virtual teams represent temporary work systems that are assembled for a joint task, performed by team members who collaborate primarily via digital technologies. Team members span geography and culture and often have only a narrow period of shared work hours. Within highly constrained temporal spaces, team members coordinate and collaborate on joint tasks with... mehr

23.11.2021 Pathways Towards the Normalization of Digital Transformations

Talk title: Pathways Towards the Normalization of Digital Transformations

Speaker affiliation: Dr. Noel Carroll, National University of Ireland Galway.

Talk abstract: Ongoing acceleration of digital transformations (DTs) poses major challenges for organizations, including needs to invest in the adoption of digital technologies, rapidly and continuously, merely to survive.... mehr
