Welcome to the Websites of the Databases and Information Systems Group (DBIS) at the department of computer science at the University of Kaiserslautern. This group exists since 08/2014 and is lead by Prof. Sebastian Michel. Together with the research groups of Prof. Härder and Prof. Deßloch it is part of the Lehrgebiet Informationssysteme.

We work on performance and quality aspects of handling Big Data, specifically for rendering large amounts of heterogeneous and evolving data accessible to users. This connects research on advanced data analytics and data exploration. We work on the development of novel algorithmic solutions, system architectures, and data indexing schemes, using and extending core database concepts as well as data mining, information retrieval, and machine learning techniques. 


In the DFG-funded Pantheon project, we investigate means to assemble entity-centric rankings based on categorical as well as numerical facts reported in entities on the Web or in knowledge bases in particular. Another research branch deals with scaling out join computations for large-scale entity matching and in general theta joins.
