NAME

WordNet::Similarity::DepthFinder - methods to find the depth of synsets in WordNet taxonomies

SYNOPSIS

use WordNet::QueryData;

use WordNet::Similarity::DepthFinder;

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

defined $wn or die "Construction of WordNet::QueryData failed";

my $obj = WordNet::Similarity::DepthFinder->new ($wn);

my ($err, $errString) = $obj->getError ();

$err and die $errString;

my @roots = $obj->getTaxonomyRoot (2855301, 'n');

my $taxonomy_depth = $obj->getTaxonomyDepth ($roots[0], 'n');

print "The maximum depth of the car#n#4's taxonomy is $taxonomy_depth\n";

my @depths = $obj->getSynsetDepth (2855301, 'n');

print "The depth of car#n#4 is $depths[0]->[0]\n";

DESCRIPTION

The following methods are provided by this module:

$obj->initialize ($configfile)

Overrides the initialize method in WordNet::Similarity to look for and process depths files. The superclass' initialize method is also called.

$obj->getSynsetDepth ($offset, $pos)

Returns the depth(s) of the synset denoted by $offset and $pos. The return value is a list of references to arrays. Each array has the form (depth, root).

$obj->getTaxonomyDepth ($offset, $pos)

Returns the maximum depth of the taxonomy rooted at the synset identified by $offset and $pos. If $offset and $pos does not identify a root of a taxonomy, then undef is returned and an error is raised.

$obj->getTaxonomies ($offset, $pos)

Returns a list of the roots of the taxonomies to which the synset identified by $offset and $pos belongs.

$obj->_processSynsetsFile ($filename)

Reads and processes a synsets file as output by wnDepths.pl

$obj->_processTaxonomyFile ($filename)

Reads and processes a taxonomies file as produced by wnDepths.pl
