Motivated by a chemical process engineering application, we introduce a new concept constructor in Description Logics (DLs), an n-ary variant of the existential restriction constr...
Number restrictions are concept constructors that are available in almost all implemented description logic systems. However, even though there has lately been considerable effort...
This paper investigates an optimization technique for reasoning with qualified number restrictions in the description logic ALCQHR+ . We present a hybrid architecture where a stan...
The use of ontologies in various application domains, such as Data Integration, the Semantic Web, or ontology-based data management, where ontologies provide the access to large am...

In this paper, we study the retrieval problem in ALN, which is a tractable concept language with number restrictions. Following the approach proposed in [12], this work differs fr...
