similarity % strings

macoda has asked for the wisdom of the Perl Monks concerning the following question:

I'm have 2 tab delimited files, both filled with 2 columns and around 5000 records, I have written the code getting perfect matches, but I also would like the code to get me all the records with a similarity of 80% and higher. Can anyone help me out!!!! The code I found on PM does not help me further. I know I should not be a difficult piece of code, but since I'm a Perl dummy...... thanks in advance, marinus

Hi, I think you should have a read at the String::Compare module documentation. The module compares two strings and return (in percentage) how much they are alike. If you need help installing modules read A Guide to Installing Modules or A guide to installing modules for Win32 depending on your platform. I notice this is your first post (with this account at least), welcome! Please have a read at the PerlMonks FAQ if you have not done so already. Hope this helps Martin	[reply]

String::Approx lets you match strings with a configurable percentage of approximateness (assuming that is what you want to do).	[reply]
