NAME

Lingua::EN::Segmenter::TextTiling - Segment text using the TextTiling method

SYNOPSIS

use Lingua::EN::Segmenter::TextTiling qw(segments);
use lib '.';

my $text = <<EOT;
Lingua::EN::Segmenter is a useful module that allows text to be split up 
into words, paragraphs, segments, and tiles.

Paragraphs are by default indicated by blank lines. Known segment breaks are
indicated by a line with only the word "segment_break" in it.

The module detects paragraphs that are unrelated to each other by comparing 
the number of words per-paragraph that are related. The algorithm is designed
to work only on long segments. 

SOUTH OF BAGHDAD, Iraq (CNN) -- Seven U.S. troops freed Sunday after being 
held by Iraqi forces arrived by helicopter at a base south of Baghdad and were 
transferred to a C-130 transport plane headed for Kuwait, CNN's Bob Franken 
reported from the scene. 

EOT
  
my $num_segment_breaks = 1;
my @segments = segments($num_segment_breaks,$text);
print $segments[0]; # Prints the first three paragraphs of the above text
print "\n----------SEGMENT_BREAK----------\n";
print $segments[1]; # Prints the last paragraph of the above text

# This module can also be used in an object-oriented fashion
my $splitter = new Lingua::EN::Splitter;
@words = $splitter->words($text);

DESCRIPTION

See synopsis.
