Proper case for names

on Sep 01, 2000 at 14:10 UTC ( #30699=perlquestion: print w/replies, xml ) Need Help??

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

Hi. I am looking for a snippet or module to proper case names, and I didn't see anything in CPAN. It seems simple, but there are special cases. Anyone have code they can share?
Fred Smith-Barney III is right, Fred Smith-barney Iii isn't
Bobby McPhillips is right, Bobby Mcphillips isn't
Lisa Top, PhD is right, Lisa Top, Phd isn't

    Look at Lingua::EN::NameCase and Lingua::EN::NameParse.

    Merlyn said it in this node RE: Uppercase First Letter w/exceptions, and I'll repeat it, you have names like O'Reilly to test for, sometimes, Mcphillips is correct, depending on the preference of the user...For this reason I don't think that a module has been written yet. You can always make one.

    If you wanted to get closer to your objective, you should shoot for "Proper case for names in the English language". IMHO, this is not a problem to be solved by perl or programming altogether. Wouldn't this be better tackled by handling the your data-entry methods?

    # Trust no1!
      Your point is well taken. Yes, entering clean data is easier than cleaning it later.
      However, I'm dealing with a large established database, with over ten million names. Errors do creep in over time...
        If you want a good method, you could try using large database of names for comparison (the phone book comes to mind) to figure out what is the likely correct capitilization of a name.

        Many companies avoid this problem all-together. Most of the bills (and other postal mail) that I receive only list my name in all-caps.

    If you're sanitizing a database, and you know that the vast majority of words are capitalized correctly, then the problem is easy to solve. Go through the database, and for each name generate the lowercase version. Keep track of how many differently-cased forms correspond to the one common lowercase form ("mckenzie" vs "McKenzie" vs "Mckenzie"). The ones that rarely occur are the mistakes, the ones that often occur are correct.

    You hope. :-)

    s/(\w+)/\u$1/g seems to work for most cases and if the input case is correct, it won't change it (i.e. McArthur remains McArthur)
