OWLAPI find all DataSomeValuesFrom of a specific class










1














This is a part of my OWL File:



# Class: :Book (:Book)

SubClassOf(:Book ObjectSomeValuesFrom(:writtenBy owl:Thing))
SubClassOf(:Book DataSomeValuesFrom(:genre rdfs:Literal))
SubClassOf(:Book DataSomeValuesFrom(:title rdfs:Literal))


How can i get only the DataSomeValuesFrom attributes?
i'm using owlapi 5.1.0
and Hermit as reasoner.



EDIT: This is how i solved. I don't know if this is the right method but it works.



Thanks to @AKSV for answer me with very useful information....



 for (OWLClass cls : o.getClassesInSignature())
Set<OWLSubClassOfAxiom> set = o.getSubClassAxiomsForSubClass(cls);
for(OWLSubClassOfAxiom subcl : set)
OWLClassExpression nomeattribEXPR = subcl.getSuperClass();
if(nomeattribEXPR.getClassExpressionType().toString().equals("DataSomeValuesFrom"))
//do something



}

  • aha, and where is the code you tried so far? load the ontology, get all subclass axioms, and then check for those with superclass being of type OWLDataSomeValuesFrom

  • I don't understand the "aha". Anyway i posted the question because i don't know how to use very well OWLAPI and all i ask is a short snippet with a short explanation.

  • Your solution works indeed. A minor improvement, you can use a "better" comparison of the class expression type by using the enum, i.e. nomeattribEXPR.getClassExpressionType() == ClassExpressionType.DATA_SOME_VALUES_FROM

Use a visitor for best effect (no need to check strings for types):



 // this is OWLAPI 5; for OWLAPI 4, use OWLObjectVisitorAdapter
OWLObjectVisitor v=new OWLObjectVisitor()
public void visit(OWLSubClassOfAxiom ax)
ax.getSuperClass().accept(this);

public void visit(OWLDataSomeValuesFrom c)
//do something

;
for (OWLClass cls : o.getClassesInSignature())
o.getSubClassAxiomsForSubClass(cls).forEach(ax->ax.accept(v));
