On Ordering Descriptions in a Description Logic
We introduce a description language for specifying partial ordering relations over concept descriptions in description logics, and show how the language can be used in combination ...

Exploiting Conjunctive Queries in Description Logic Programs
We present cq-programs, which enhance nonmonotonic description logics (dl-) programs by conjunctive queries (CQ) and union of conjunctive queries (UCQ) over Description Logics kno...

EXPTIME Tableaux for ALC Using Sound Global Caching
We show that global caching can be used with propagation of both satisfiability and unsatisfiability in a sound manner to give an EXPTIME algorithm for checking satisfiability w...

Conjunctive Query Entailment for SHOQ
An important reasoning task, in addition to the standard DL reasoning services, is conjunctive query answering. In this paper, we present a decision procedure for conjunctive query...

Modal Logic Applied to Query Answering and the Case for Variable Modalities
We present a query answering technique based on notions and results from modal Correspondence Theory. It allows us to answer a wide family of conjunctive queries by polynomial redu...
