Hi Esther,

WordNet::QueryData is a Perl module that has some handy functionality
with offsets.

http://search.cpan.org/dist/WordNet-QueryData/QueryData.pm

Below is an example where I get the offset for a synset specified by a
word#pos#sense (note that QueryData uses the first word,pos,sense in a
sysnet as a unique identifier for the synset, so it's refereeing to
the entire synset, not just that particular one) and then I use that
offset to get back the word. Note that if you don't give the part of
speech to the getSense method you will get back the word and the sense
number - I don't remember the details of why that is, but hopefully
this gives you some idea of what it can do with offsets.

marimba(1749): more qd5.pl

use WordNet::QueryData;
my $wn = WordNet::QueryData->new;

$wps = 'cat#n#1';

$offset = $wn->offset("$wps");
print "offset of $wps $offset\n";

$pos = 'n';
$wordForm = $wn->getSense($offset,$pos);
print "with pos : $wordForm\n";

$wordForm = $wn->getSense($offset);
print "without pos : $wordForm\n";

---------------------

marimba(1750): perl qd5.pl
offset of cat#n#1 2121620
with pos : cat#n#1
without pos : cat##1

Enjoy,
Ted
