Lingua::NameUtils - Identify given/family names and capitalize correctly
Lingua::NameUtils is a perl module containing functions that can split a person's full name into their given and family names, and capitalize the letters appropriately. It understands complex names in Latin scripts from many different languages, and it understands Chinese, Japanese, and Korean names, in both their own characters, and romanized.
This module is useful when receiving a person's name that might be all uppercase, or in the wrong case, or it might have the given names and the family name combined in a single string (e.g., a single spreadsheet column), and you need to split the full name into its parts, and you want to set the capitalization correctly so as to show each person a little respect by taking the trouble to at least try to get their name right.
Getting the case right for people's names is difficult, and many software systems address this problem by not even trying, and using uppercase exclusively. It's ugly, but it's easy and consistent. We can do better. It can't be perfect, by default, but with ongoing adjustments to suit your evolving dataset, you can improve it to meet your needs.
People with complex grammatical aristocratic/topographic/patronymic family names often don't know how their own names should be capitalized. Or at least, they don't know how their own ancestors capitalized their name, or they know, but they disagree with it. Some people insist on having it their own way, and that's fine. This module, by default, prefers how their ancestors would have capitalized their names, but people can do whatever they want to their own names, and it's important to them, so this module supports general exceptions that apply to everyone with a particular family name, for when the default behaviour is definitely wrong, and it also supports exceptions that apply only to individuals who report that it is wrong for them.
Note: This module doesn't handle every name on Earth. Apart from Chinese, Japanese, and Korean family names, it only understands names written in Latin scripts, except perhaps by lucky accident. For example, names in Cyrillic work. It doesn't handle honorifics, titles, joined initials, or postnominals. It only handles names. But it does handle complex names coming from a variety of places (e.g., British Isles, Europe, Middle East, Africa, East Asia, Pacifika, Americas). By default, it doesn't correctly identify unhyphenated multi-name family names (like Spanish and Catalan names, unless the formal "y" or "i" is present). Such names need to be handled with split exceptions. It handles some mixed case names like McAdam, MacArthur, FitzSimmons, DeVito, VanZandt, etc., but there will be false negatives (and arguably false positives) which can be corrected with case exceptions. Over time, you will build up a set of case exceptions and split exceptions that meets the needs of your dataset.
