A Hypertableau Calculus for SHIQ
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...

Progression of Situation Calculus Action Theories with Incomplete Information
In this paper, we propose a new progression mechanism for a restricted form of incomplete knowledge formulated as a basic action theory in the situation calculus. Specifically, w...
