Extracting Finite Sets of Entailments from OWL Ontologies
The canonical standard description logic reasoning service is classification, that is, the generation of the set of atomic subsumptions which are entailed by some ontology. While ...

Unchain My EL Reasoner
We study a restriction of the classification procedure for EL++ where the inference rule for complex role inclusion axioms (RIAs) is applied in a “left-linear” way in analogy ...

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,...

A hierarchical approach to reachability query answering in very large graph databases
The cost of reachability query computation using traditional algorithms such as depth first search or transitive closure has been found to be prohibitive and unacceptable in mass...

On Tail Distribution of Interpost Distance
A partial order on Z obtained by taking the transitive closure of a random relation {i < j and there is an edge ij} is studied. Randomness stems from postulating that an edge ij...

Event Matching Using the Transitive Closure of Dependency Relations
This paper describes a novel event-matching strategy using features obtained from the transitive closure of dependency relations. The method yields a model capable of matching eve...

On Impossibility of Decremental Recomputation of Recursive Queries in Relational Calculus and SQL
We study the problem of maintaining recursively-de ned views, such as the transitive closure of a relation, in traditional relational languages that do not have recursion mechanis...

Computing the Transitive Closure of a Union of Affine Integer Tuple Relations
Abstract. This paper proposes a method to compute the transitive closure of a union of affine relations on integer tuples. Within Presburger arithmetics, complete algorithms to com...
