PSPACE Tableau Algorithms for Acyclic Modalized $\boldsymbol{\mathcal{ALC}}$


We study $\mathcal{ALCK}_m$ and $\mathcal{ALCS}4_m$ , which extend the description logic $\mathcal{ALC}$ by adding modal operators of the basic multi-modal logics K m and S4 m . We develop a sound and complete tableau algorithm $\Lambda_\mathcal{K}$ for answering $\mathcal{ALCK}_m$ queries w.r.t. an $\mathcal{ALCK}_m$ knowledge base with an acyclic TBox… (More)
