public class ConfidenceCurvatureFilter
extends MatcherYAAAJena
implements Filter

Filters the alignment by computing the inflection point of the sorted confidences. To make it more stable a smoothing (spline interpolation) can be used. Furthermore also the elbow point of the confidences can be used to filter them.

Method Details

match

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.
