      Constructor
      Parameters:
      strict - if true, filter all correspondences where the host can not be determined. If false, also include correspondences where the host could not be determined.

      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

      target - This OntModel represents the target ontology.
      inputAlignment - This mapping represents the input alignment.
      properties - Additional properties.
      Returns:
      The resulting alignment of the matching process.
      Throws:
      Exception - Any exception which occurs during matching.
