Traditionally, description logic (DL) research has concentrated on reasoning about the conceptual modeling of a domain, as provided e.g. by an ontology. This kind of reasoning is not sufficient when DLs are used in applications that emphasize instance data, such as information integration and ontology- mediated data access. In the last couple of years, this shortcoming has stimulated lively research on (instance) query answering in DLs. The talk gives an overview of the area and presents and summarizes recent results for query answering in expressive and lightweight DLs.
