CHANGES - Revision history for Text::Similarity

DESCRIPTION

0.07

Released November 14, 2008 (all changes by TDP)

• Changed test case that was tripping up Windows. In Linux these are treated as being the same (when order doesn't matter) but this is not the case in Windows.

  'sir winston churchill' 'winston churchill SIR!!!' 

  The case has been changed to :

  'sir winston churchill' 'winston churchill sir' 

0.06

Released April 5, 2008 (all changes by TDP)

• Added Dice coefficient to Overlaps.pm output. Dice is equivalent to F-measure, but formulated slightly differently so could be useful to catch errors.

• Modified Overlaps method to provide lesk text matching score, that is the sum of the squared lengths of all phrasal matches (optionally normalized by the product of the lengths of the strings). It provides both Raw lesk and lesk (the normalized form) when run in verbose mode.

• Reogranized some documentation to make it more clear that Overlaps is just one possible way of measuring similarity, and that other methods can and should be added.

• Renamed text_compare.pl as the more natural and fitting text_similarity.pl

0.05

Released April 4, 2008 (all changes by TDP)

• Made it possible for users to input strings directly via text_compare.pl and getSimilarityStrings. Previously it was only possible to directly measure the similarity of files, but now strings can be measured.

0.04

Released March 21, 2008 (all changes by TDP)

• Introduced tests for text_compare.pl (t/text_compare.t) - added support for os neutral file reads via FILE::SPEC in this and other .t files.

• Introduced tests for getOverlaps (t/overlaps.t)

• Improved synopsis examples to show how to pass options via arguments in hashes

• Clarified that stemming and compounding are not currently supported disabled compfile option in text_compare.pl

• Made file handling in text_compare more robust so that when a file does not exist an error message is given and failure is immediate

• Changed method of passing constants in test cases from (eg.) "Text::Similarity::NORMALIZE" to "normalize" in order to support backwards compatability with perl 5.6.

• Introduce normalize and no-normalize tests for getSimilarity

• Fix Similarity.pm Synopsis example not to use files in /t that are no longer available

0.03

Released March 20, 2008 (all changes by TDP)

• fix divide by zero errors reported on cpan by cernst at esoft.com, who also provided fix

• update test cases to improve coverage of partial matches and no matches

• update synopsis examples so they can be run via cut and paste

• improve README content to make it more descriptive

• introduce /doc directory for pod of INSTALL README and CHANGES

• introduce 'use constant' to support perl 5.6
