Many description logics (DLs) combine knowledge tation on an abstract, logical level with an interface to “concrete” domains such as numbers and strings. We propose to extend ...

The paper proposes some applications of description logic reasoning techniques in web–based education environments. Current solutions are web oriented but without applying ontolo...
In this extended abstract an optimization technique, the so-called signature calculus, for reasoning with number restrictions in description logics is investigated. The calculus i...
We compare and contrast Description Logic (DL) and Order-Sorted Feature (OSF) Logic from the perspective of using them for expressing and reasoning with knowledge structures of the...
We present a new tableaux calculus deciding the ABox consistency problem for the expressive description logic ALCNHR+ . Prominent language features of ALCNHR+ are number restricti...
