public interface SynsetSimilarity

An interface for determining the similarity between two Synsets. Implementations are the same measures provided by the perl WordNet::Similarity package distributed by Ted Pedersen.

The similarity measures come in three varieties: measures based on the paths between two synsets, measures based on information content for each synset, and a combination of path information and information content.

Implementations should take a OntologyReader as an argument to the contructor and may take other arguments via the constructor, such as a InformationContent instance. All calls to similarity should be free of state changes and thus thread safe.
