Our group focusses on the theory and algorithmics of the extraction of information from data. In particular, the research concentrates on the algorithmic questions in designing information systems that have to deal with large, and ever more quickly growing, amounts of data. Such data may be stored in many varieties, from neatly organised databases to unordered documents on the web. The fundamental principles of fitting search methods, data mining and knowledge discovery and the design of algorithmic technology for this form some of the major challenges in the field. The research context consists of the many datarich environments in which information systems for domain research and support have to be devised. Important applications that drive our fundamental research aim at solving problems encountered in, for example, the biomedical domain.
