From f8ec91676cfdeefc302100033a1b38167d01490f Mon Sep 17 00:00:00 2001 From: Federico Igne Date: Fri, 4 Dec 2020 17:21:32 +0000 Subject: Fix axiom skolemization Skolemization should be uniquely bound to the axiom being skolemized. When an axiom is a shortcut for a set of axioms, the skolemization strategy should be updated with the new axiom(s). --- .../scala/uk/ac/ox/cs/rsacomb/OWLAxiomSpec.scala | 16 +--- .../scala/uk/ac/ox/cs/rsacomb/OWLClassSpec.scala | 102 ++++++++++----------- 2 files changed, 56 insertions(+), 62 deletions(-) (limited to 'src/test/scala/uk/ac/ox/cs') diff --git a/src/test/scala/uk/ac/ox/cs/rsacomb/OWLAxiomSpec.scala b/src/test/scala/uk/ac/ox/cs/rsacomb/OWLAxiomSpec.scala index d39dec7..e1ece62 100644 --- a/src/test/scala/uk/ac/ox/cs/rsacomb/OWLAxiomSpec.scala +++ b/src/test/scala/uk/ac/ox/cs/rsacomb/OWLAxiomSpec.scala @@ -36,13 +36,7 @@ import tech.oxfordsemantic.jrdfox.logic.expression.{ import org.semanticweb.owlapi.model.{IRI => OWLIRI} import tech.oxfordsemantic.jrdfox.logic.expression.{IRI => RDFIRI} -import uk.ac.ox.cs.rsacomb.converter.{ -
