Extract a person's full name from a block of text in Perl?

Extract a person's full name from a block of text in Perl?

I need to extract names (including uncommon names) from blocks of text using Perl. I've looked into this module for extracting names, but it only has the top 1000 popular names and surnames in the US dating back to 1990; I need something a bit more comprehensive.

I've considered using the Social Security Index to make a database for comparison, but this seems very tedious and processing intensive. Is there a way to pull names from Perl using another method?

Example of text to parse:

There is no sure fire way to do this due to the nature of the English language. You either need lists to (fuzzy)compare with, or will have to settle for significant accuracy penalties.

You're trying to implement a named-entity recognition. The bad news is that it's really hard. You could try Lingua::EN::NamedEntity, however:

$ perl -MLingua::EN::NamedEntity -nE 'say $_ for map { $_->{class} eq "person" ? $_->{entity} : () } extract_entities($_)' names.txt   Louie  Louis Anthony Ladnier  Louie  John E  Bayou La Batre Police Department  Gloria  Julian  Cindy  Eddie Ladnier  Eddie  John  Catholic Church  Christian Rubio  Dominic Ladnier  Burma Road Mobile  Louie  

You can also use Calais, a Reuters webservice for natural language processing, which offers a lot better results:

The Apache Foundation has a few projects that cover the topic of entity extraction with specific pre-trained models for English names (nameFinder). I would recommend openLNP or Stanbol. In the meantime if you have just a few queries I have an NLP I've implemented in C# in my apps section at http://www.augmentedintel.com/apps/csharpnlp/extract-names-from-text.aspx.

Best,

Don

Use Stanford's NER (GPL). Demo:
