Using quantitative models of simple mechanisms as an example domain, we show how the basic principles of consistency-based diagnosis can be implemented using description logics wi...

We describe a method for characterizing the expressive power of description logics. The method is essentially model-theoretic in nature, and it is applied to obtain expressiveness...

We consider two recently proposed definitions of the expressive power of description logics, one due to Baader, the other due to Kurtonina and de Rijke. The proposals are non-equi...

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 ...
