Contextualization of a DL Knowledge Base
Abstract. In the paper we propose a method of structuring a knowledge base into hierarchically related contexts and present how this arrangement influences the structure of TBox a...

Blocking Automata for PSPACE DLs
In Description Logics (DLs), both tableau-based and automata-based algorithms are frequently used to show decidability and complexity results for basic inference problems such as c...

A Proof Theory for DL-Lite
Abstract. In this work we propose an alternative approach to inference in DLLite, based on a reduction to reasoning in an extension of function-free Horn Logic (EHL). We develop a ...

Speeding up Approximation with Nicer Concepts
Abstract. Concept approximation is an inference service for Description Logics that provides “translations” of concept descriptions from one DL to a less expressive DL. In [4] ...

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...

DL-based Alternating-offers Protocol for Automated Multi-issue Bilateral Negotiation
Abstract. We present a novel approach to logic-based bilateral negotiation in ecommerce systems. We use Description Logics to describe both requests/offers submitted by buyers and ...

Distributed Description Logics Revisited
Distributed Description Logics (DDLs) is a KR formalism that enables reasoning with multiple ontologies interconnected by directional semantic mapping (bridge rules). DDLs capture ...
