Lingua::EN::MatchNames - Smart matching for human names.
$score= name_eq( $firstn_0, $lastn_0, $firstn_1, $lastn_1 );
You have two databases of person records that need to be synchronized or matched
up, but they use different keys--maybe one uses SSN and the other uses
employee id. The only fields you have to match on are first and last name.
That's what this module is for.
Just feed the first and last names to the "name_eq()" function, and it
returns "undef" for no possible match, and a percentage of certainty
(rank) otherwise. The ranking system isn't very scientific, and gender isn't
considered, though it probably should be.
The "name_eq()" function, checks for:
- inconsistent case (MacHenry = Machenry = MACHENRY)
- inconsistent symbols (O'Brien = Obrien = O BRIEN)
- misspellings (Grene = Green)
- last name hyphenation (Smith-Curry = Curry)
- similar phonetics (Hanson = Hansen)
- nicknames (Midge = Peggy = Margaret)
- extraneous initials (H. Ross = Ross)
- extraneous suffixes (Reed, Jr. = Reed II = Reed)
- and more...

The scoring in this version is utterly arbitrary. I made all of the numbers up.
The certainty percentages should be OK relative to each other, but would be
better if someone could give me some statistical data.
Be sure and test
this against your data first! Your data may not look
like my test data.
And although I hope this is useful to many, I do not provide any kind of
warranty (expressed or implied), and do not suggest the suitability of this
module to any particular purpose. This module probably should not be used for
life support or military purposes, and it must
not be used for
unsolicited commercial email or other bulk advertising.
