The nominal datatype package implements an infrastructure in Isabelle/HOL for defining languages involving binders and for reasoning conveniently about alpha-equivalence classes. P...
Abstract. While many higher-order interactive theorem provers include a choice operator, higher-order automated theorem provers currently do not. As a step towards supporting autom...
Abstract. We consider the problem of specifying and computing consistent answers to queries against databases that do not satisfy given integrity constraints. This is done by simul...

Abstract. To make ABox reasoning scalable for large ABoxes in description logic (DL) knowledge bases, we develop a method for partitioning the ABox so that specific kinds of reaso...
We present a novel reasoning calculus for the Description Logic SHIQ. In order to reduce the nondeterminism due to general inclusion axioms, we base our calculus on hypertableau an...
