This paper investigates optimization techniques and data structures exploiting the use of so-called pseudo models. These techniques are applied to speed-up TBox and ABox reasoning...
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...
Sonic1 is the first prototype implementation of non-standard inferences for Description Logics that can be used via a graphical user interface. In addition to that our implementat...
