Span with Sentence detection #3

Closed yoshie902a closed 11 years ago

Hi, firstly, thanks for the hard work on the wrapper!

Just one quick question. What is the syntax to do this...

Span sentences[] = sentenceDetector.sentDetect(" First sentence. Second sentence. ");

I need to input a sentence and get the sentence boundaries points as an index of start and stop locations.

I also need the sentences...

string sentences[] = sentenceDetector.sentDetect(" First sentence. Second sentence. ");

Looking through your examples, I was not too sure about sentence detection in this manner. Sorry if this is a basic question. I'm new to this. You examples, could have even shown it, but might be misunderstanding them.

thanks you!

Hi,

Here's how:

text = "Put your sentences here."
segmenter = OpenNLP::SentenceDetectorME.new
sentences = segmenter.sent_pos_detect(text)

sentences.each do |sentence|
  start = sentence.get_start
  stop  = sentence.get_end-1
  str   = text[start..stop]
end

Cheers,

Louis
