The research group Knowledge-Based Systems is concerned with methods for the intelligent management and processing of information in computer systems. This includes research questions from knowledge representation, reasoning and formal logic, but also covers topics related to databases and distributed systems. Important application areas of this research can be found in the fields of semantic technologies, artificial intelligence, and knowledge management.
The research group is affiliated with the Institute for Theoretical Computer Science.
