Research fields in the Department of Computer Science

The Department of Computer Science covers the following research fields with its 8 institutes:

 

Research Field Algorithmics

Prof. Dr. Stefan Funke

Our research focuses on the development of algorithms that not only work “well” for typical input data from an application domain but for which we can also show certain properties (running time, quality of the outcome, ...) via rigorous mathematical proofs. Current research topics are algorithms in the context of route planning, E-mobility, self-localization, industrial packing problems, scheduling as well as text retrieval. Further information here.

Research Field Applications of Parallel and Distributed Systems

Prof. Dr. Bernhard Mitschang

The Department of Application Software sees its "traditional" area of work in the large field of database and information systems. Added to the classic topics such as data models, languages and optimisation are current research topics, for example data integration, data analysis and techniques of data warehousing as well as scalable data processing and data-intensive applications, for instance in technical application fields. Further information here.

Research Field Architecture of Application Systems

Prof. Dr. Frank Leymann

The research deals with the structure, the modelling and the runtime support of applications critical to companies. In so doing business process or service oriented approaches, their middleware and development tools are often in the foreground. Current research deals with cloud computing, management of distributed applications, sample languages, quality of service features and applications of the aforementioned technologies in various fields. Further information here.

Research Field Computational Linguistics

Jun.-Prof. Dr. Lonneke van der Plas

The junior professorship in Computational Linguistics, headed by Junior Professor Lonneke van der Plas, is located in the field of computational semantics. Among other things it deals with cross-lingual methods, whereby the lexical and structural variation between languages is used in order to automatically record predicate argument structures or the meaning of words. This information is used, for example, in order to extract terminology from texts or to optimise question-answer-systems or dialogue systems with semantic information, e.g. with synonyms or semantic roles. Further information here.

Research Field Data Engineering

Prof. Dr. Melanie Herschel

In the field of data engineering Prof. Herschel is particularly interested in data provenance, data integration, data cleaning (especially entity resolution), and data-centric workflow processing. The overarching goal of her research is to automatically prepare and engineer massive heterogeneous data for use in various real-life applications. Further information here.

Research Field Embedded Systems

Prof. Dr.-Ing. Martin Radetzki

The special field of embedded systems deals with architectures and design methods for hardware and software systems in technical applications. Research focal points are pursued in the fields of modelling and parallel simulation of embedded systems, the design of robust systems as well as the architecture of error-tolerant on-chip-connection networks. Further information here.

Research Field Experimental Phonetics

Prof. Dr. Grzegorz Dogil

The Chair of Experimental Phonetics is known for its technological research in the field of speech synthesis, for basic research on intonation (prosody) and syllable structure as well as for computational modeling and simulation of language perception and language production, in particular using exemplar-theoretical models.

Further information here.

Research Field Foundations of Computational Linguistics

Prof. Dr. Jonas Kuhn

Our research centers around the question: What are adequate formalisms for modeling the structural and semantic relationships between linguistic units. Particular emphasis is on the combination of statistical techniques for extracting knowledge from large data collections with linguistic know-how. In the area of "Digital Humanities", our group is actively involved in the transfer of research findings from computational linguistics to text analysis tasks in the humanities. Further information here.

Research Field Intelligent Systems

Prof. Dr.-Ing. Andrés Bruhn

Main research is performed in the fields of computer vision, image processing and scientific computing. Current research topics are the estimation of motion information from image and stereo sequences, the 3-D reconstruction from binocular and multiview data, the recovery of shape information from from shading, as well as the qualitative enhancement and compression of images and videos. From a methodical viewpoint global optimisation problems as well as their efficient numerical implementation are in the focus of our research. Further information here.

Research Field Machine Learning and Robotics

Prof. Dr. Marc Toussaint

Our research focusses on the combination of decision theory and machine learning, motivated by applications in robotics. The goal are learning systems that are able to reason about their own state of knowledge (e.g., in a Bayesian way) and decide which actions might yield the most informative future data, make them learn even better and eventually solve problems. We address this in the form of Reinforcement Learning, Planning and Active Learning in probabilistic relational domains. Further, a growing focus of our lab are real-world robotic systems, including trajectory optimization and optimal control methods. Further information here.

Research Field Human-Computer-Interaction

Prof. Dr. Albrecht Schmidt

In the special field of man-computer-interaction we research mobile, ubiquitous as well as linked and embedded sensor technologies and their interaction with the user. In current research projects, for example, the possibility of the cognitive improvement of human skills through technology, the potentials of a linked sensor technology in museums are investigated to design interactive exhibitions as well as requirements and best-practice-concepts for assistance systems for production processes that are based on movement recognition and projected images. Further information here.

Prof. Dr. Sven Simon

The focus of research is, on the one hand, parallel computer architecture on the basis of reconfigurable hardware and parallel processors (multi-core processors, graphics processing units), in particular for quick image-forming systems in the context of natural science and engineering applications. On the other hand, innovative design methods for high-performance hardware systems with Gbit/s data connections on the basis of image forming process are the objective of the research work.
