Computational Logic

The Computational Logic (CL) group is focusing on modeling and reasoning aspects of logic-based knowledge representation. We are interested both in the mathematical and formal foundations of diverse knowledge representation paradigms but also in their application in areas like the Semantic Web, knowledge acquisition, argumentation, etc. Motivated by requirements encountered in these fields, we also conduct research in adjacent areas like database theory and computational linguistics.
The Computational Logic Group also has a Facebook page, a Twitter account, and a YouTube channel.
