Method Detail

aboxToGraph

public static org.jgrapht.Graph<org.semanticweb.owlapi.model.OWLIndividual,org.jgrapht.graph.DefaultEdge> aboxToGraph(org.semanticweb.owlapi.model.OWLOntology ont)

Maps the ABox of an OWL ontology to a directed graph.

It just uses object property assertions to build the graph of the individuals. Edges are not labeled.

Parameters:

ont - the ontology

Returns:

a directed graph with labeled vertices

aboxToLabeledGraph

public static org.jgrapht.Graph<org.semanticweb.owlapi.model.OWLIndividual,OWLPropertyEdge> aboxToLabeledGraph(org.semanticweb.owlapi.model.OWLOntology ont)

Maps the ABox of an OWL ontology to a labeled directed graph.

It just uses object property assertions to build the graph of the individuals. Edges are labeled with the object property.

Parameters:

ont - the ontology

Returns:

a directed graph with labeled vertices and edges

aboxToLabeledGraphWithTypes

public static org.jgrapht.Graph<TypedOWLIndividual,OWLPropertyEdge> aboxToLabeledGraphWithTypes(org.semanticweb.owlapi.model.OWLOntology ont)

Maps the ABox of an OWL ontology to a labeled directed graph.

It just uses object property assertions to build the graph of the individuals. Edges are labeled with the object property. Vertices are annotated with the types of the individuals.

Parameters:

ont - the ontology

Returns:

a directed graph with labeled and type annotated vertices as well as labeled edges

main

public static void main(String[] args)
                 throws org.semanticweb.owlapi.model.OWLOntologyCreationException

Throws:

org.semanticweb.owlapi.model.OWLOntologyCreationException
