NAME
   README - General information about Text::Similarity

DESCRIPTION
   Text-Similarity is a Perl module that allows a user to measure the
   similarity between two strings or two files. There is one method for
   computing similarity supported Text::Similarity::Overlaps, and others
   can be added.

   When using Text::Similarity::Overlaps, text similarity is based on
   counting the number of overlapping words between the two files, and is
   (optionally) normalized by the length of the files.

   The lesk value provided in Text::Similarity::Overlaps is based on
   counting the number of overlapping words and phrases between the two
   files, and is (optionally) normalized by the length of the files.
   Phrasal matches are scored more highly.

   The smallest unit we are considered for matches are white space
   separated strings. 'the cat and the hat' and 'these cats and these hats'
   will only result in similarity between 'and', matches below the word
   level are not measured.

   Each input file is treated as a single string. There are methods
   provided that allow you to write programs that measure files for
   similarity (getSimilarity) and identifying the overlaps present in
   strings (getOverlaps).

CONTENTS
   When the distribution is unpacked, several subdirectories are created:

   /bin
       This directory contains a driver program called text_similarity.pl
       that can be used to conveniently measure two files for similarity.
       Please see the perldoc for this program for more details.

   /lib
       This directory contains the Perl modules that do the actual work of
       disambiguation. By default, these files are installed into
       /usr/local/lib/perl5/site_perl/PERL_VERSION (where PERL_VERSION is
       the version of Perl you are using). See the INSTALL file for more
       information.

   /doc
       This directory contains all of the *pod files used to document the
       system. These are processed via pod2text and the output of this is
       placed in the top level directory, although these top level text
       files should be considered read only.

   /t  This directory contains test scripts. These scripts are run when you
       execute 'make test'.

   /samples
       It includes two formats of stoplist file, one word per line
       (stoplist.txt) and regular expression format (stoplist-nsp.regex).
