NAME ^

install.pod - how to install WordNet::Similarity

SYNOPSIS ^

 perl Makefile.PL

 make

 make test

 make install

DESCRIPTION ^

Prerequisites

You need to have WordNet (version 2.1) installed, WordNet::QueryData (version 1.39 or later), and Text::Similarity installed.

WordNet is available at http://wordnet.princeton.edu, WordNet::QueryData is available from http://search.cpan.org/dist/WordNet-QueryData, and Text::Similarity is available from http://search.cpan.org/dist/Text-Similarity.

You should set the WNHOME environment variable to the location where you have WordNet installed; see the WordNet::QueryData documentation for more information.

Installing

The usual way to install the package is to run the following commands:

 perl Makefile.PL

 make

 make test

 make install

If you can't set the WNHOME environment variable, you can use the WNHOME option when running perl Makefile.PL. For example,

 perl Makefile.PL WNHOME=/usr/local/WordNet-2.1

You will often need root access/superuser priviledges to run make install. The module can also be installed locally. To do a local install, you need to specify a PREFIX option when you run 'perl Makefile.PL'. For example,

 perl Makefile.PL PREFIX=/home/sid

or

 perl Makefile.PL LIB=/home/sid/lib PREFIX=/home/sid

will install Similarity into /home/sid. The first method above will install the modules in /home/sid/lib/perl5/site_perl/5.8.3 (assuming you are using version 5.8.3 of Perl; otherwise, the directory will be slightly different). The second method will install the modules in /home/sid/lib. In either case the executable scripts will be installed in /home/sid/bin and the man pages will be installed in home/sid/share.

Warning: do not put a dash or hyphen in front of PREFIX, LIB or WNHOME.

In your perl programs that you may write using the modules, you may need to add a line like so

 use lib '/home/sid/lib/perl5/site_perl/5.8.3';

if you used the first method or

 use lib '/home/sid/lib';

if you used the second method. By doing this, the installed modules are found by your program. To run the similarity.pl program, you would need to do

 perl -I/home/sid/lib/perl5/site_perl/5.8.3 similarity.pl

or

 perl -I/home/sid/lib

Of course, you could also add the 'use lib' line to the top of the program yourself, but you might not want to do that. You will need to replace 5.8.3 with whatever version of Perl you are using. The preceeding instructions should be sufficient for standard and slightly non-standard installations. However, if you need to modify other makefile options you should look at the ExtUtils::MakeMaker documentation. Modifying other makefile options is not recommended unless you really, absolutely, and completely know what you're doing!

NOTE: The information-content based measures (res, lin, jcn) are invoked using the default information content file generated during installation of the modules. If, however, the version of WordNet being used on your system has changed since that time, or for some reason the modules are unable to locate the default information content files, then alternate information content files can be specified only by using a configuration file corresponding to each of the modules. Format and creation of configuration files has been discussed in the documentation. Utilities to generate information content files have been provided in the package.

NOTE: If one (or more) of the tests run by 'make test' fails, you will see a summary of the tests that failed, followed by a message of the form "make: *** [test_dynamic] Error Y" where Y is a number between 1 and 255 (inclusive). If the number is less than 255, then it indicates how many test failed (if more than 254 tests failed, then 254 will still be shown). If one or more tests died, then 255 will be shown. For more details, see:

http://search.cpan.org/dist/Test-Simple/lib/Test/Builder.pm#EXIT_CODES

System Requirements

  1. Perl version 5.6 or later. This package has been written in Perl, which is freely available from www.perl.org. This package assumes that perl is installed in the directory /usr/local/bin. If this is where perl is on your computer, then the support programs can be run directly at the command line as 'similarity.pl ...' or 'semCorFreq.pl...', etc. However, if Perl is not installed at this location, you would need to explicitly invoke them as 'perl similarity.pl ... ' or 'perl freqCount.pl...', etc.
  2. WordNet: All the measures are based on WordNet. WordNet must be installed on your system. WordNet is freely downloadable from http://wordnet.princeton.edu. WordNet version 2.1 was used during the development and testing of the package. Unfortunately, due to major changes in WordNet (and WordNet::QueryData) from version 2.0 to 2.1, this version of WordNet::Similarity supports only WordNet 2.1 (or later). The WordNet::QueryData Perl module is used to access WordNet. This module requires that an environment variable 'WNHOME', containing the path to the WordNet files, be set up. For further details, please see the WordNet::QueryData documentation.
  3. WordNet::QueryData: This is the Perl interface to WordNet written by Jason Rennie. QueryData should be accessible on the @INC path of Perl. (Can be freely downloaded from http://search.cpan.org/dist/WordNet-QueryData). QueryData 1.39 was used during the development. Also we observed that that due to some major changes in QueryData from its previous versions, this software does not work with the earlier versions of QueryData. If you have an earlier version of QueryData (1.38 or earlier) you may need to upgrade QueryData.
  4. Text::Similarity: This module is used by the WordNet::Similarity::lesk measure for finding runs of word overlaps in glosses. The Text::Similarity module can be downloaded from http://search.cpan.org/dist/Text-Similarity.

Optional Tests

Running 'make install' after make will run a short series of tests. These tests should not take more than a few minutes to run. There is another series of more rigorous tests that may also be run; however, these tests can take quite some time to run (over an hour on some machines). To run these tests, run 'make test_all'.

Example

The following procedure will work on most Linux systems.

 cd /tmp
 wget http://wordnet.princeton.edu/2.1/WordNet-2.1.tar.gz
 wget http://search.cpan.org/CPAN/authors/id/J/JR/JRENNIE/WordNet-QueryData-1.39.tar.gz
 wget http://search.cpan.org/CPAN/authors/id/J/JA/JASONM/Text-Similarity-0.02.tar.gz
 wget http://search.cpan.org/CPAN/authors/id/T/TP/TPEDERSE/WordNet-Similarity-1.01.tar.gz

Then unpack each one:

 tar -zxvf WordNet-2.1.tar.gz
 tar -zxvf WordNet-QueryData-1.39.tar.gz
 tar -zxvf Text-Similarity-0.02.tar.gz
 tar -zxvf WordNet-Similarity-1.01.tar.gz

Install WordNet:

 cd /tmp/WordNet-2.1
 ./configure
 make
 su
 make install
 exit

Installing QueryData and Similarity:

 cd /tmp/WordNet-QueryData-1.39
 perl Makefile.PL
 make
 make test
 su
 make install
 exit

 cd /tmp/Text-Similarity-0.02
 perl Makefile.PL
 make
 make test
 su
 make install
 exit

 cd /tmp/WordNet-Similarity-1.01
 perl Makefile.PL
 make
 make test
 su
 make install
 exit
