We are pleased to announce the release of version 0.07 of Text-Similarity. This package allows you to measure the similarity between two text documents using a variety of measures. This release includes a single fix to a test case that had caused problems with Windows installations. Please see the change log for more details. http://text-similarity.sourceforge.net
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'
We are pleased to announce the release of version 0.06 of Text-Similarity! This package now includes support for the lesk measure and the Dice Coefficient. Please see http://text-similarity.sourceforge.net for additional details.
0.06 Released April 6, 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
