A logical calculus with descriptions
Journal of Philosophical Logic, 1974is well-formed but not derivable though it is an instance of the tertium non datur. This fact suggests to attempt a similar treatment of descriptions: formulas which contain terms like zx(A (x) A ~A (x)) are considered as wff but the tertium non datur does not hold generally for such formulas.

Pinpointing in the Description Logic EL. [PDF]
Axiom pinpointing has been introduced in description logics (DLs) to help the user understand the reasons why consequences hold by computing minimal subsets of the knowledge base that have the consequence in question. Until now, the pinpointing approach has only been applied to the DL ALC and some of its extensions.

Autoepistemic Description Logics. [PDF]
We present Autoepistemic Description Logics (ADLs), in which the language of Description Logics is augmented with modal operators interpreted according to the nonmonotonic logic MKNF. We provide decision procedures for query answering in two very expressive ADLs.

A Logical Semantics for Description Logic Programs
2010We present a new semantics for Description Logic programs [1] (dl-programs) that combine reasoning about ontologies in description logics with non-monotonic rules interpreted under answer set semantics. Our semantics is equivalent to that of [1], but is more logical in style, being based on the logic QHT of quantified here-and-there that provides a ...

Autoepistemic Description Logics.
AI Commun., 1998A non-first-order extension of description logics (DL) which is able to both formalize the nonmonotonic features of knowledge representation (KR) systems, and to provide a computational characterization of reasoning in such a setting, is defined.

Fusion of Logic Programming and Description Logics
2009Broadly, our research concerns the fusion of Logic Programming (LP) andDescription Logics (DLs), two solid knowledge representation paradigms with largely dual properties.The two feature different semantics and orthogonal expressivity, and they apply different reasoning techniques.
