Research Group for Knowledge Engineering

The research group Knowledge Engineering conducts research and development in the area of security and privacy in Cloud Computing and Service-Oriented Computing.
Another emphasis lies on technological foundations and applications of Not-Only-SQL (NOSQL) databases.
The research group also investigates topics at the intersection of databases (in particular, Cloud databases), artificial intelligence (using Semantic Web technology) and mathematical logic. A particular focus is given to intelligent security mechanisms for databases by combining logics and cryptography.
