English abstract:
Description Logics (DLs) play a central role as formalisms for representing ontologies and reasoning about them. They are the logical underpinning of the OWL languages for the Semantic Web, and are increasingly employed in many application areas. This lecture will introduce the basics of DLs. We will discuss the knowledge modeling capabilities of some of the most prominent DLs and present some classic DL reasoning services, like classification, consistency, and instance checking. In the second part of the lecture we will approach the use of DL ontologies for data access, and introduce the increasingly popular framework in which data repositories are queried through DL ontologies. We will discuss the main challenges that arise in this setting and describe some query answering techniques.
