UMLS::Similarity - A suite of Perl modules that implement a number of semantic similarity measures in order to calculate the similarity between two concepts in the UMLS. The measures use the UMLS-Interface module to access the UMLS present in a mysql database.
This package consists of Perl modules along with supporting Perl programs that implement the semantic relatedness measures described by Leacock & Chodorow (1998), Wu & Palmer (1994), Nguyen and Al-Mubaid (2006), Rada, et. al. 1989, Patwardhan (2003),...
