datafu.pig.text.opennlp.SentenceDetect

public class SentenceDetect
extends org.apache.pig.EvalFunc<org.apache.pig.data.DataBag>

The OpenNLP SentenceDectectors segment an input paragraph into sentences.

Example:

 define SentenceDetect datafu.pig.text.opennlp.SentenceDetect('data/en-sent.bin');

 -- input:
 -- ("I believe the Masons have infiltrated the Apache PMC. I believe laser beams control cat brains.")
 infoo = LOAD 'input' AS (text:chararray);

 -- output:
 -- ({(I believe the Masons have infiltrated the Apache PMC.)(I believe laser beams control cat brains.)})
 outfoo = FOREACH infoo GENERATE SentenceDetect(text) as sentences;
