About

Our research is located at the interface between methods from Theoretical Computer Science (such as logic, algorithmics, approximation, and complexity theory) and their application to various areas of Computer Science such as Database Theory, Artificial Intelligence Knowledge Representation & Reasoning, Scheduling and Planning as well as Graph Theory.

The overall research goal of our work is to understand the inherent computational complexity of problems in those areas, and then use these insights to define novel concepts and algorithms towards efficient practical solutions.

More specifically, topics covered by our research include Database Query Languages, Information Integration, the Semantic Web, Description Logics, Ontology-based Data Access, Formal Argumentation, Belief Change, Computational Social Choice, Answer-set Programming, Automated Timetabling and Scheduling.

Databases and Artificial Intelligence is part of the faculty’s Institute of Logic and Computation.
