(Nicht-)Standard-Inferenztechniken im Semantic Web

Sebastian Wandelt

This seminar discusses standard and non-standard inference techniques for Semantic Web ontologies. In particular, we will look into recent work on description logics.

Each student will have to prepare a talk (30 minutes) about a selected topic. In addition, each student has to prepare to be an opponent for another selected talk. An opponent is supposed to be able to raise critical questions about a given topic. Finally, each student has to hand in a seminar paper for his selected topic.


Basic knowledge in logics (propositional logic, first order logic) is recommended.


Please register at Goya. The number of participants is limited.
