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.
|25.04.2017||Lunchtime Seminar - Smart Contracts and the Automation of Law||
Smart Contracts are computer protocols aiming at linking law and reality. The concept has resurfaced in the wake of the recent hype around Blockchain technology which provides crucial features for the automation of the execution of agreements in peer-to-peer relationships. This talk will address some of the potentials and limitations relating to the automation of law and will elaborate on the differences of smart contracts and law.

In this talk we will present a framework for processing knowledge inconsistency in a collective using consensus computing. The model of knowledge inconsistency has been built with several inconsistency measures. We will show that inconsistency degree of a collective has an essential impact on the quality of collective knowledge. In addition to inconsistency degree, the number of collective members, the problem of collective knowledge increase, additional knowledge elements, multi-stage... more

The increasing amount of data being generated on a daily basis has empowered the development of novel products and services. However, this data deluge has clear impacts on our everyday lives, turning usual activities, such as selecting destinations for vacation, choosing a movie on a streaming platform, or purchasing a suitable car, into puzzling situations in which there is no standard method to find an appropriate decision. To solve problems like these, personalized applications (from Web... more
|24.01.2017||Lunchtime Seminar - Crowdsourcing the Assessment of Humanitarian Logistics Infrastructure and Resources||
Humanitarian aid organizations respond to disasters by delivering relief items in highly complex and dynamic environments. To plan and execute logistics operations therein, it is crucial to build and maintain situation awareness. That is, to perceive the relevant elements of the environment, to comprehend their meaning and to project their status in the near future. Traditional data sources, such as direct observation by assessment teams, are limited in terms of speed and coverage.... more
|17.01.2017||Lunchtime Seminar - Decision Support for Efficient Utilization of Energy Storage||
Energy storage technologies, such as pumped hydro or batteries, are considered as key building blocks of future energy systems. Systems with a high share of intermittent renewable energy sources may use storage for balancing energy supply and demand. As Germany aims at a share of 80% energy from renewables by 2050, the federal government sees storage technologies as potential enablers of the Energy Turnaround.
However, the utilization of energy storage crucially depends on its... more
|10.01.2017||Lunchtime Seminar - Ad hoc Integration for Big Data – Top-k Entity Augmentation Using Web Tables||
In the era of Big Data, the number and variety of data sources is increasing every day. However, not all of this new data is available in well-structured databases or data warehouses. Instead, heterogeneous collections of individual datasets such as data lakes are becoming more prevalent. This novel wealth of data, though not integrated, has enormous potential for generating value in ad-hoc analysis processes, which are becoming more and more common with increasingly agile data management... more
|13.12.2016||Lunchtime Seminar - Data Profiling as a Process||
Dealing with data necessitates understanding data, which can be facilitated by analyzing its metadata. This metadata is often not readily available, and thus, needs to be extracted and collected. This activity is called data profiling and is well established and researched in the literature. However, what is missing is a structured description of a holistic data profiling process that brings the various tools, techniques and algorithms together. The goal is to achieve a guideline that helps... more
|06.12.2016||Lunchtime Seminar - Bitcoin & the law – selected legal issues of cryptocurrencies||
The use of cryptocurrencies, like Bitcoin, is steadily growing. Bitcoins are used in e-commerce to purchase both legal and illegal goods, they are transferred and traded, and investors have brought a significant amount of capital to this virtual currency. While the technical aspects of the system are meanwhile well established, many legal questions remain open. Particularly, the de-central organization of the peer-to-peer network makes it difficult to apply existing law. The talk gives an... more
|22.11.2016||Lunchtime Seminar - Contract Design Choices and the Balance of Ex Ante and Ex Post Transaction Costs in Software Development Outsourcing||
In his talk, Yossi Lichtenstein presents his research on Software Development outsourcing contracts that he published together with Michel Benaroch and Lior Fink in MIS Quarterly this year (Vol 40(1)). His research addresses two under-studied themes in IT outsourcing. The first is about balancing specification costs and hazard costs in drafting contracts. The second theme is the fact that contracts serve multiple functions including safeguarding, coordination and adaptability. As an... more
|08.11.2016||Lunchtime Seminar - Professor Joan Rodón Mòdol||
Research on the evolutionary dynamics of mobile ecosystems, web browser ecosystems, social networking systems, enterprise software ecosystems, and national eHealth infrastructures is increasingly gaining the attention of the literature on information systems. Unlike administrative enterprise systems and individual applications, these large-scale infrastructures exhibit unbounded (or open-ended) evolution.
