NAME

AI::Classifier::Japanese - the combination wrapper of Algorithm::NaiveBayes and Text::MeCab.

SYNOPSIS

use AI::Classifier::Japanese;

# Create new instance
my $classifier = AI::Classifier::Japanese->new();

# Add training text
$classifier->add_training_text("たのしい．楽しい！", 'positive');
$classifier->add_training_text("つらい．辛い！", 'negative');

# Train
$classifier->train;

# Test
my $result_ref = $classifier->predict("たのしい");
print $result_ref->{'positive'}; # => Confidence value
