      de.unima.alcomox.ontology.LocalOntology

Direct Known Subclasses:

IOntology

public class LocalOntology
extends AlcomoOntology

This class represents a local possibly extended ontology. Two of these extandable ontologies are used for the pairwise efficient but incomplete reasoning.

Constructor Summary

LocalOntology(java.lang.String filepathOrUrl)
Constructs an ontology, thats a kind of wrapper for an owl ontology, by reading a file specified by a filepath or url.

Method Summary

Entity	getEntityByUri(java.lang.String entityUri) Resolves the uri reference and returns the entity that the uri refers to.

void	init(ExtractionProblem extractionProblem) Inits this extandable ontology and binds it to the extraction problem.
boolean	isUnsatisfiable(org.semanticweb.owlapi.model.OWLClass c) Checks the unsatisfiability of a class.

Constructor Detail

LocalOntology

public LocalOntology(java.lang.String filepathOrUrl)
              throws AlcomoException

Constructs an ontology, thats a kind of wrapper for an owl ontology, by reading a file specified by a filepath or url.

Parameters:

filepathOrUrl - The string representation of the filepath or URL.

Throws:

AlcomoException - Thrown if filepath or url do not refer or the file is somehow corrupted /not valid.

Method Detail

getEntityByUri

public Entity getEntityByUri(java.lang.String entityUri)
                      throws OntologyException

Resolves the uri reference and returns the entity that the uri refers to.

Parameters:

entityUri - The uri of the entity as string.

Returns:

Entity refered to by entityUri

Throws:

OntologyException - Thrown if entityUri does not refer to some named entity in the ontology.

init

public void init(ExtractionProblem extractionProblem)
          throws OntologyException

Inits this extandable ontology and binds it to the extraction problem. Initalising an extandable ontology results in extending the ontology and building up some indices. Finally the extended ontology is classified.

Parameters:

extractionProblem -

Throws:

OntologyException

AlcomoException

getRandomEntity

public Entity getRandomEntity()

getRandomEntity

public Entity getRandomEntity(boolean isConcept)

getReferencedClassUris

public java.util.Set<java.lang.String> getReferencedClassUris()

isUnsatisfiable

public boolean isUnsatisfiable(org.semanticweb.owlapi.model.OWLClass c)

Description copied from class: AlcomoOntology

Checks the unsatisfiability of a class.

Overrides:

isUnsatisfiable in class AlcomoOntology

Parameters:

c - The class that has to be checked for unsatisfiability.

Returns:

True if c is unsatisfiable, false otherwise.

getNextExtId

public int getNextExtId()
