We address the problem of introducing preferences into default logic. Two approaches are given, one a generalisation of the other. In the first approach, an ordered default theory...
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 ...

This chapter covers extensions of the basic description logics introduced in Chapter 2 by very expressive constructs that require advanced reasoning techniques. In particular, we ...
