About Anni-Yasmin Turhan

I am head of the group Knowledge Representation. My research interests are the foundations of logic-based Systems. The core of such systems are reasoning problems for logis. In my research, I investigate the properties of such problems in regard of the formalism in use and develop reasoning procedures.

Primarily, I work on Description Logics (DLs), which are decidable fragments of first-orderlogic and can model terminologies from application domains in a declarative way. The modelled concepts can semantically enrich data and allow to infer new information. The main focus of my current research is on methods for symbolic learning (of concepts) in DLs and on "robust" queries over DL knowledge bases, which are inconsistency-tolerant or admit relaxation of queries.

Teaching

Teaching Areas

The courses held by the Knowledge Representation group mainly focus on logics and logical reasoning. Here, the main taught notions and methods often come from theoretical computer science, for example decidability, comutational complexity and proof methods. Thus we offer in the bachelor studies courses with topics from theoretical computer science. In the master studies, we offer courses on the foundational logics used for knowledge representation and their reasoning problems. There are courses on description Logics and on logics for nonmonotonic reasoning.


Current Courses

  • Seminar: Advanced topic on Description Logics (in English)
  • Modellierung
  • Knowledge Base Engineering (in English)
