public class NaiveDescendingExtractor
extends MatcherYAAAJena
implements Filter

Naive descending extraction as shown in "Analyzing Mapping Extraction Approaches" (C. Meilicke, H. Stuckenschmidt). It iterates over the sorted (descending) correspondences and and uses the correspondence with the highest confidence. Afterwards removes every other correspondence with the same source or target. Previously it was called CardinalityFilter aka GreedyExtractor.

public Alignment match(org.apache.jena.ontology.OntModel source,
 org.apache.jena.ontology.OntModel target,
 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:

source - This OntModel represents the source ontology.

target - 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.
