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.

10.10.2017 Lunchtime Seminar - What types of techniques have been applied in process mining?

Although process mining can no longer be considered a really new research area, it still has many opportunities and challenges, as the solutions presented are still weak compared to real-world needs. Process mining can be defined as a research discipline between “machine learning and data mining” on the one hand and “process modeling and analysis” on the other hand. However, how much machine learning has actually been applied in process mining? What about computational intelligence... more

25.07.2017 Lunchtime Seminar - Conceptual Model for Data Warehouse Systems

Jörg presents a conceptual model as basis for BI systems. Many companies suffer from inconsistent data in their data warehouse systems, and quite often, there is more than one of these in a company installed. Every new requirement of a department in a company concerning aggregated data results in a new report the IT department builds fulfilling these requirements. What we observe are hundreds of dimension tables and thousands of facts tables in different systems (Cognos, SAP SD, SAP CRM, SAP... more

18.07.2017 Lunchtime Seminar - Business Apps with MAML: A Model-Driven Approach to Process-Oriented Mobile App Development

Business apps are used by non-technical users in everyday work routines. However, the creation of apps still follows traditional software development practices and is exclusively performed by software developers that need to centrally collect requirements and domain knowledge. Moreover, few modeling approaches focus on platform-agnostic representations of mobile apps. Recent advances such as textual domain-specific languages for cross-platform app generation reduce development efforts, but... more

11.07.2017 Lunchtime Seminar - Computational Semiotics and The Semiotic Machine – A Primer

Abstract: Electronic Digital Computers have been the driving force of most technological advances worldwide, for over 40 years now. Despite the huge advances afforded and the high technological content embedded in them, digital processing has still been performed, chiefly, in a von Neumann manner. And even if we consider the foremost advanced hardware and software approaches, namely parallel platforms and intelligent algorithms, respectively, nowadays computers still have a... more

04.07.2017 Lunchtime Seminar - What makes technology-driven innovation disruptive? The role of interpretive discontinuity

A well-known yet poorly understood phenomenon of radical innovations is that their disruptive potential is frequently missed initially, but appears entirely self-evident with hindsight. We name this phenomenon “interpretive discontinuity”. We propose to consider disruption akin to a Kuhnian revolution. By demonstrating direct parallels between paradigm shifts in scientific fields and technology-induced industry disruptions, we show that disruption is a shift in worldview that fundamentally... more

27.06.2017 Lunchtime Seminar - IT design as a vanishing and foregrounding performance: from immersive to open virtual learning environment

What are the manoeuvres through which designers seek to address opposition and rally strategic actors? We draw on an ethnographic work conducted within a start-up where we have traced the design of a 3D virtual learning environment, using game technologies, intended for geologists. In analysing the data, we identify four episodes in the design of a virtual learning environment: imagining the software; mapping ideologies; designing affordances; and enacting the infrastructure. Crucially, the... more

20.06.2017 Lunchtime Seminar - The Chief Digital Officer – First Insights into a New Management Role

The digital transformation has become a critical management issue and requires new ways of managerial thinking. As a reaction, more and more companies are installing Chief Digital Officer (CDO) positions to support the progress of their digital transformation. Overall, we know little about this new role, which is one of the fastest-growing phenomena at top mana­ge­ment level. The aim of this talk is therefore to compile first and recent empirical findings. In detail, we initially (1) try to... more

13.06.2017 Lunchtime Seminar - A typology for selecting an appropriate Total Landed Cost method in international supplier selection decisions

The Total Landed Cost (TLC) often comprises of a large share of the total international sourcing costs and thereby determines the cost saving potential. Nevertheless, different studies clearly show that companies often underestimate the true costs, with the consequence of yielding less than expected savings or in fact uneconomical results.On the one hand, companies often have to deal with a set of different international supplier selection situations, on the other hand the literature deals... more

30.05.2017 Lunchtime Seminar - The ERCIS Network – Past, Present, and Future

The European Research Center for Information Systems (ERCIS) is somehow omnipresent in the Department’s day-to-day life. There are banners at the buildings, people drink their beverages from ERCIS cups, and the slide master is well-known to everyone. In this talk, Armin will provide an overview about the past of the network, its current state, and its potential future. As you are most probably a member of the network without even knowing, the talk is intended to make you aware of the idea... more

23.05.2017 Lunchtime Seminar - Automated Deep Learning

Machine Learning is omnipresence nowadays, for example face and speech recognition on your smartphone and other smart devices. The recent breakthroughs in many modern AI applications are due to deep learning (specifically deep neural networks). That is because deep learning scales better to big data, enables native end-to-end learning, and has established new state-of-the-art performance on many applications. However to get an accurate deep learning model, users have to make many important... more
