[topicmapmail] Fwd: CPAN release of WordNet::Similarity

[Bob Parks]

Greetings:
Does anyone know of work being done to measure the semantic distance 
among nodes in a topic map?  Some tools for measuring semantic 
distance in WordNet were just released to CPAN (below).
Thanks,
Bob

>We are pleased to announce the CPAN release of the WordNet::Similarity

>http://search.cpan.org/author/SID/WordNet-Similarity-0.03/

>This package consists of Perl modules along with supporting Perl programs
>that implement the semantic similarity measures of Leacock-Chodorow 
>(1998), Jiang-Conrath (1997), Resnik (1995), Lin (1998), Hirst-St Onge
>(1998) and Banerjee-Pedersen (2002). The package contains Perl modules 
>designed as object classes with methods that take as input two word 
>senses from WordNet. These methods can be embedded in any Perl program 
>and will return the semantic similarity between the senses according to 
>the requested measure.
>
>There are also support programs for generating information content values 
>(Resnik 1995) for WordNet concepts from a variety of corpora, including 
>the BNC, Penn Treebank, Semcor, or any raw text provided by a user. The 
>information content values are required by the measures of Jiang-Conrath, 
>Lin, and Resnik, and could also be useful in a wide range of WordNet based
>applications. 
>
>The package also provides a simple command line interface that returns the 
>similarity measure of two given words. This is very similar to our
>earlier version of the Distance package. A number of switches and options  
>have been provided to enhance the output with trace data and other 
>information.
>
>Please download and give Similarity a try! We anxiously await your 
>feedback and suggestions.
