  • Field Details

    • homogenousDraw

      protected boolean homogenousDraw
      If true, then all negatives are of the same type e.g. class, property, instance.

    • withRepetitions

      protected boolean withRepetitions
      If true, then it will samples random elements which can also appear multiple times in different correspondences. If false, then all sampled entities for e.g. the target ontology will not contain any entities which are already used in the alignment or are randomly sampled before.

  • Method Details

    • getSampler

      protected RandomSampleSet<String> getSampler(String resource, org.apache.jena.ontology.OntModel m, RandomSampleOntModel sampleModel)
      Returns the correct sampler for the given resource contained in given model. In case homogenousDraw is set to true, it will sample from same same entity e.g. sample a class for a class.
      Parameters:
      resource - the resource to check which concept type should be sampled
      m - the model corresponding to resource
      sampleModel - the RandomSampleOntModel.
      Returns:
      the random sampler.

    • sampleResource

      protected String sampleResource(String resource, org.apache.jena.ontology.OntModel m, RandomSampleOntModel sampleModel)
      Sample a resource from sampleModel given the resource in model m. In case homogenousDraw is set to true, it will sample from same same entity e.g. sample a class for a class.
      Parameters:
      resource - the resource to check which concept type should be sampled
      m - the model corresponding to resource
      sampleModel - the model to sample from.
      Returns:
      the random element.

    • sampleResource

      protected String sampleResource(String resource, org.apache.jena.ontology.OntModel m, RandomSampleOntModel sampleModel, Set<String> excludes)
      Sample a resource from sampleModel given the resource in model m. In case homogenousDraw is set to true, it will sample from same same entity e.g. sample a class for a class. It will exclude
      Parameters:
      resource - the resource to check which concept type should be sampled
      m - the model corresponding to resource
      sampleModel - the model to sample from.
      excludes - the set contains elements which should not be chosen as a random sample.
      Returns:
      the random element.

    • isHomogenousDraw

      public boolean isHomogenousDraw()
      If homogenousDraw is true, then all negatives are of the same type e.g. class, property, instance.
      Returns:
      true, if all negatives are of the same type e.g. class, property, instance.

    • setHomogenousDraw

      public void setHomogenousDraw(boolean homogenousDraw)
      Sets the homogenousDraw value. If true, all negatives are of the same type e.g. class, property, instance.
      Parameters:
      homogenousDraw - true, if all negatives are of the same type e.g. class, property, instance.

    • isWithRepetitions

      public boolean isWithRepetitions()
      If true, then it will samples random elements which can also appear multiple times in different correspondences. If false, then all sampled entities for e.g. the target ontology will not contain any entities which are already used in the alignment or are randomly sampled before.
      Returns:
      true, if with repetitions

    • setWithRepetitions

      public void setWithRepetitions(boolean withRepetitions)
      If set to true, then it will samples random elements which can also appear multiple times in different correspondences. If false, then all sampled entities for e.g. the target ontology will not contain any entities which are already used in the alignment or are randomly sampled before.
      Parameters:
      withRepetitions - true, if with repetitions
