WordNet::Tools - Some tools for use with WordNet.


  use WordNet::QueryData;

  use WordNet::Tools;

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

  my $wntools = WordNet::Tools->new($wn);

  my $wnHashCode = $wntools->hashCode();

  my $newstring = $wntools->compoundify("find compound words like new york city in this text");


This module provides some tools for use with WordNet. For example, the 'compoundify' method detects compound words (as found in WordNet) in a text string and it combines these words into single tokens using underscore separators. Another tool in this module generates a unique hash code corresponding to a WordNet distribution. This hash code is meant to replace the "version" information in WordNet, which is no longer reliable.


The following methods are defined:


This is a constructor for this class (and creates a new object of this class). It requires a WordNet::QueryData object as a parameter.

Parameters: $string -- an input text string.

Returns: a string with compound words identified.


This method returns the list of compound words present in WordNet.

Parameters: none
