Class WuPalmerSimilarity

java.lang.Object
  gov.llnl.ontology.wordnet.sim.WuPalmerSimilarity

All Implemented Interfaces:

SynsetSimilarity

public class WuPalmerSimilarity
extends Object
implements SynsetSimilarity

Implements the Wu-Palmer Similarity. This measure scores Synsets based on the depth of the two Synsets in the taxonomy and their lowest common subsumer, i.e. the deepest node in the tree that is a hypernym of both Synsets. This lowest common subsumer is not always the same as the shared hypernym that forms the shortest path between the two Synsets. When there are multiple subsumers, the subsumer with the longest path to the root of the taxonomy is selected.
