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.

Pre-computed Pairwise Similarity Values for Nouns and Verbs
We are pre-computing all pairwise similarity values for all senses in WordNet,
slowly but surely. This began in June 2010 - by March 2011 we had
completed all verb pairs for all similarity measures, and in August 2011
we completed all noun pairs for the path measure. We continue to work on the
other measures.

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.
