Orel: Database-Driven Reasoning for OWL 2 Profiles
We describe Orel, a reasoning system for an ontology language which subsumes both the EL and the RL profile of the recently standardised web ontology language OWL 2. Orel performs ...

The Logical Difference For Fuzzy EL+ Ontologies
Abstract. Ontologies undergo changes for reasons such as changes in knowledge, meeting varying application requirements. Thus, for different versions of a considered ontology, it i...

Decidability of Description Logics with Transitive Closure of Roles in Concept and Role Inclusion Axioms
Abstract. This paper investigates Description Logics which allow transitive closure of roles to occur not only in concept inclusion axioms but also in role inclusion axioms. First,...

Role-depth Bounded Least Common Subsumers by Completion for EL- and prob-EL-TBoxes
The least common subsumer (lcs) w.r.t general EL-TBoxes does not need to exists in general due to cyclic axioms. In this paper we present an algorithm for computing role-depth boun...

Optimizing Algebraic Tableau Reasoning for SHOQ: First Experimental Results
In this paper we outline an algebraic tableau algorithm for the DL SHOQ, which supports more informed reasoning due to the use of semantic partitioning and integer programming. We ...
