WordNet::Similarity

This is a Perl module that implements a variety of semantic similarity and relatedness measures based on information found in the lexical database WordNet. In particular, it supports the measures of Resnik, Lin, Jiang-Conrath, Leacock-Chodorow, Hirst-St.Onge, Wu-Palmer, Banerjee-Pedersen, and Patwardhan-Pedersen.

We have a mailing list designed to support users of WordNet::Similarity.

Information Content Computed on Various Corpora
We have pre-computed information content files from the British National Corpus (World Edition), the Penn Treebank (version 2), the Brown Corpus, the complete works of Shakespeare, and SemCor (with and without sense tags). These were created using the *Freq.pl programs found in WordNet::Similarity. These information content files should be used with WordNet::Similarity for the given version of WordNet.
