  fr.inrialpes.exmo.align.util.OntologyNetworkWeakener

public class OntologyNetworkWeakener
extends Object

OntologyNetworkWeakener A utility class that transform an ontology network in one with less alignments/

Constructor Summary

OntologyNetworkWeakener()

Method Summary

static OntologyNetwork	dropAlignments(OntologyNetwork on, double n) randomly drops n% of all alignments n is a number between 0.
static OntologyNetwork	unconnect(OntologyNetwork on, int n) suppress alignments in the ontology network so that it retain n-connectivity, i.e., any pairs of ontologies connected by less than n alignments are still connected through at most n alignments.
static OntologyNetwork	weakenAlignments(OntologyNetwork on, double n, boolean threshold) suppress n% of the correspondences at random in all alignments n is a number between 0.

Method Detail

unconnect

public static OntologyNetwork unconnect(OntologyNetwork on,
                                        int n)

suppress alignments in the ontology network so that it retain n-connectivity, i.e., any pairs of ontologies connected by less than n alignments are still connected through at most n alignments. JE: this is an interesting graph theoretic problem and I do not know where to find it.

weakenAlignments

public static OntologyNetwork weakenAlignments(OntologyNetwork on,
                                               double n,
                                               boolean threshold)
                                        throws AlignmentException

suppress n% of the correspondences at random in all alignments n is a number between 0. and 1. Returns a brand new BasicOntologyNetwork (with new alignments and cells) the @threshold parameter tells if the corrrespondences are suppressed at random (false) of by suppressing the n% of lower confidence (true)

Throws:

AlignmentException

dropAlignments

public static OntologyNetwork dropAlignments(OntologyNetwork on,
                                             double n)
                                      throws AlignmentException

randomly drops n% of all alignments n is a number between 0. and 1. Returns a brand new BasicOntologyNetwork (with the initial alignments)

Throws:

AlignmentException
