Class WordNetCondenser

java.lang.Object
  gov.llnl.ontology.wordnet.WordNetCondenser

public class WordNetCondenser
extends Object

This runnable class creates a series of feature vectors for every synset reachable from the noun "entity" Synset. Competing Synsets for every noun lemma are merged using agglomerative merging. The similarity between any two Synsets is the average simiarlity of the created feature vectors for the two Synsets, along with any additional features created by a SynsetPairFeatureMaker. The resulting WordNet hierarchy is then saved to disk.
