An ExpSpace Tableau-based Algorithm for SHOIQ
Chan Le Duc 1, Myriam Lamolle 1, 2, Olivier Curé 3
(2012-06-02)

In this work, we propose an ExpSpace tableau-based algorithm for deciding consistency of a knowledge base in the description logic SHOIQ. The construction of this algorithm is founded on the standard tableau-based method for SHOIQ and the technique used for designing a NExpTime algorithm for the two-variable fragment of first-order logic with counting quantifiers C^2.
