This chapter considers, on the one hand, extensions of Description Logics by features not available in the basic framework, but considered important for using Description Logics a...
This system description provides an overview of the MUNCH reasoner for sets and multisets. MUNCH takes as the input a formula in a logic that supports expressions about sets, multi...
In this paper, we incorporate concrete domain and action theory into a very expressive Description Logic (DL), called ALCQO. Notably, this extension can significantly augment the ...

We investigate whether identification constraints such as keys and functional dependencies can be granted full status as a concept constructor in a Boolean-complete description log...
