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.

13.11.2018 Lunchtime Seminar - Evolutionary Computing for Problems with Dynamically Changing Constraints

Dynamic problems appear frequently in real-world applications such as logistics for mining and are usually subject to a large set of constraints. These constraints change over time due to changes in resources and having algorithms that can deal with such dynamic changes delivers direct benefit to decision makers. Evolutionary algorithms are well suited for such dynamic problems as they can easily adapt to changing environments. In this talk, I will report on some... more

20.11.2018 Lunchtime Seminar - Virtual relationships as patterns of intercorporeal engagements
Abstract:   Technological advances and increased pervasiveness of ICTs have afforded the emergence of distributed and virtual forms of organizing and collaborating. It has been suggested that research on virtual interactions is still missing appropriate understanding of the processes of developing intersubjective relations and social bonding in virtual context. Research in the area has been dominated by polar stances. On one hand, there have been claims for the... more
27.11.2018 Lunchtime Seminar - Thinking about public policy - hard choices and soft advice

This seminar will look at the ways in which economists and others  contribute to public policy debates. How public policy debates are formed, influenced and evaluated.  The seminar will focus on the high technology sector (success as Telecommunications and platforms - although some other issue such as natural capital will be discussed).

One of the issues that will permeate the discussion is the nature of benefits, how these are created (e.g. through innovation) , how these benefits are... more

04.12.2018 Lunchtime Seminar - Webcam Covering as Planned Behavior

Most of today’s laptops come with an integrated webcam placed above the screen to enable video conferencing. Due to the risk of webcam spying attacks, some laptop users seem to be concerned about their privacy and seek protection by covering the webcam. We are the first to investigate personal characteristics and beliefs of users with and without webcam covers by applying the Theory of Planned Behavior. We record the privacy behavior of 180 users, develop a path model, and... more

08.01.2019 Lunchtime Seminar - Machine Understanding for Enterprise Applications

In his talk Prof. Löser will briefly review main drivers for the platform economy and will sketch important implications for the German economy. Later, he will introduce their work on neural text mining for enterprise applications. In particular, he will focus on tasks such as in-database text mining, sentence classification, entity linkage, Hate-speech detection and neural paragraph retrieval. Finally, Prof. Löser will outline latest trends and his ‘bets’ in the area of neural text mining... more

15.01.2019 Lunchtime Seminar - Discovering Design Features of Artificial Intelligence (AI) for the Knowledge-based Work of the Future: A Socio-Technical Analysis

Abstract:   Knowledge-based work has realized across industries and jobs, and the infiltration of AI into this work comes exponentially with advance of technologies. In this regard, Artificial intelligence (AI) produces a series of design features in this knowledge work environment of the future. The purpose of this study is to discover a variety of AI design features in the future-oriented knowledge-based work by a view of socio-technical perspective. To elucidate divergent... more

22.01.2019 Lunchtime Seminar - Online-propaganda, disinformation & emotional Manipulation – Interdisciplinary Approaches to understand and combat manipulative online-communication in the DemoRESILdigital group.

Abstract. Our society becomes more and more digitalized. Beyond new opportunities for democratic participation, this also offers new opportunity structures for the dissemination of manipulative content such as populist or extremist online-propaganda, fake news, or emotionally manipulative content. Counter-strategies, which focus solely on the repression of such contents, are limited by both the speed and dynamic of digital dissemination channels, as well... more

29.01.2019 Lunchtime Seminar - Towards the automated Design of Heuristic-Based algorithms for lot-sizing problems

Supply chains and production environments, especially in high wage countries like Germany, are constantly becoming more dynamic and complex for several decades already. This development finds its most recent peak in the advent of Industrie 4.0, in which it is intended to enable production systems to be reconfigurable and flexible, manufacturing products in vastly varying amounts and constantly changing specifications. Such changes of course influence the planning model that creates the base... more

09.04.2019 Multimodality in Multi-Objective Optimization - More Boon than Bane?

This talk addresses a new perspective on multimodality of multi-objective (MO) optimization landscapes.  In Operations Research, we learn that local optima are traps for local opimizers. Interestingly, this fact is simply transfered to multi-objective optimization as certainty as well, although we do not have enough insights into multi-objective landscape characteristics. In our work, we use sophisticated visualization techniques, which rely on gradient fi eld heatmaps and enable a... more

16.04.2019 Increasing Model Utilization in Software Engineering

"Model-Driven Software Development is widely adopted throughout research and industry" is a sentence that often opens scientific papers regarding model-driven software engineering. While it is true that models are widely adopted they are often not utilized to their full extent. Therefore, efficiency enhancement potential and inherent insights remain unused. The talk presents the current status of research on increasing model utilization in software engineering. The audience will understand... more
