Constructor Detail

ExtendedSnowEtAlFeatureMaker

public ExtendedSnowEtAlFeatureMaker(OntologyReader wordnet,
                                    List<String> synsetVectorLabels)

Creates a new ExtendedSnowEtAlFeatureMaker. No sense clustering is used.

ExtendedSnowEtAlFeatureMaker

public ExtendedSnowEtAlFeatureMaker(OntologyReader wordnet,
                                    String senseMergedFilename,
                                    List<String> synsetVectorLabels)

Creates a new ExtendedSnowEtAlFeatureMaker.

Method Detail

numExtraFeatures

protected int numExtraFeatures()

Returns the number of extra features.

Overrides:

numExtraFeatures in class SnowEtAlFeatureMaker

addExtraAttributes

protected void addExtraAttributes(List<String> attributeList)

Appends extra attribute labels.

Overrides:

addExtraAttributes in class SnowEtAlFeatureMaker

addExtraFeatures

protected void addExtraFeatures(Synset sense1,
                                Synset sense2,
                                edu.ucla.sspace.vector.DoubleVector featureVector,
                                int index)

Adds the distributional similarity score for sense1 and sense2 for each of the specified ontological vectors associated with each synset. If either word sense lacks one of the ontological vectors, this stores for that feature 0.
