    • match

      public Alignment match(org.apache.jena.ontology.OntModel sourceOntology, org.apache.jena.ontology.OntModel targetOntology, Alignment inputAlignment, Properties p) throws Exception
      Description copied from class: MatcherYAAAJena
      Aligns two ontologies specified via a Jena OntModel, with an input alignment as Alignment object, and returns the mapping of the resulting alignment. Note: This method might be called multiple times in a row when using the evaluation framework. Make sure to return a mapping which is specific to the given inputs.
      Specified by:
      match in interface IMatcher<org.apache.jena.ontology.OntModel,Alignment,Properties>
      Specified by:
      match in class MatcherYAAAJena
      Parameters:
      sourceOntology - This OntModel represents the source ontology.
      targetOntology - This OntModel represents the target ontology.
      inputAlignment - This mapping represents the input alignment.
      p - Additional properties.
      Returns:
      The resulting alignment of the matching process.
      Throws:
      Exception - Any exception which occurs during matching.

    • initializeMappingProcess

      private void initializeMappingProcess(Alignment inputAlignment)
      (Re-)initialize data structures.
      Parameters:
      inputAlignment - Input alignment

    • match

      Given two iterators, match the resources covered by them.
      Parameters:
      sourceOntologyIterator_1 - iterator 1 must be that of the source ontology
      targetOntologyIterator_2 - iterator 2 must be that of the target ontology

    • performSimpleMatching

      private void performSimpleMatching(Map<String,Set<String>> uri2labelMap_1, Map<String,Set<String>> uri2labelMap_2)

      Parameters:
      uri2labelMap_1 - URI 2 labels for the source ontology.
      uri2labelMap_2 - URI 2 labels for the target ontology.

      Returns:
      Converted HashMap.

    • normalize
