Hi Hamed,

Thanks for your interest in Text-Similarity. See my comments inline...

The following code (from
http://search.cpan.org/dist/Text-Similarity/lib/Text/Similarity.pm)
will give you just the Lesk (overlap) measure. This is not actually
the same thing as "semantic relatedness", so if you are interested in
that you might want to look at the lesk measure as found in
WordNet::Similarity, which is based on the use of Text::Similarity but
does some other things too. Text::Similarity (for lesk) simply finds
the overlaps between two strings or files.

  use Text::Similarity::Overlaps;
      my $mod = Text::Similarity::Overlaps->new;
      defined $mod or die "Construction of Text::Similarity::Overlaps failed";

      # adjust file names to reflect true relative position
      # these paths are valid from lib/Text/Similarity
      my $text_file1 = 'sent11.txt';
      my $text_file2 = 'sent21.txt';

      my $score = $mod->getSimilarity ($text_file1, $text_file2);
      print "The similarity of $text_file1 and $text_file2 is : $score\n";

You could use the following type of reference :

Pedersen, Ted (2008)
Text-Similarity (version 0.07) : A Perl Module to Measure the
Pair-Wise Similarity of Files or Strings
http://search.cpan.org/dist/Text-Similarity/

Good Luck!
Ted
