php - How to Split a Paragraph into Sentences

Question

I've been trying to use:

$string="The Dr. is here!!! I am glad I'm in the U.S.A. for the Dr. quality is great!!!!!!";
preg_match_all('~.*?[?.!]~s',$string,$sentences);
print_r($sentences);

But it doesn't work on Dr., U.S.A., etc.

Does anyone have any better suggestions?

Answer 1

there is not any simple solution for that. you need do some natural language processing(NLP) in your application and recognize each sentence. there is something call OpenNLP, it's a JAVA-based NLP parser tool. Or Stanford NLP parser in Ruby. you can find something like that for php.

here I found a set of classes for natural language processing in PHP.
