I'm working on a perl-based CGI frontend to a MySQL database and am looking for a good way to do duplicate detection. While it's easy to do a simple match on one field, what I'm looking to do is use a more complex algorithm to compare several different fields and produce a sorted list of database records that are most likely to be similar. False positives are fine, this is more to present the user with a list of 5 or 10 possibilities they can scan to see if the record they are adding is similar to one already in the database.

While I've found some academic papers on the subject that look promising, I'm looking for something that while not readymade, the algorithm is at least demonstrated in perl.

Modules like String::Similarities look good, does anyone have any recomendations on other tools for this type of work?
