Mail::Classifier::GrahamSpam 0.13

Mail::Classifier::GrahamSpam is a spam classification tool based on Paul Grahams algorithm.

SYNOPSIS

use Mail::Classifier::GrahamSpam;
$bb = Mail::Classifier::GrahamSpam->new();
$bb->bias( NOTSPAM, 2);
$bb->train( { spam.mbox => SPAM, notspam.mbox => NOTSPAM } );
my ($cat, $prob) = $bb->score( $msg );

ABSTRACT

Mail::Classifier::GrahamSpam - spam classification based on Paul Grahams algorithm

This class is a specific implementation of a Mail::Classifier that uses Naive Bayesian methods for associating messages with a category. The specific implemenation is based on the article "A Plan for Spam" by Paul Graham (thus the name).
For classic Graham, make sure to set bias on non-spam to 2.
While this class was designed to classify spam and non-spam, there is no underlying limitation that only two categories be used and thus it may be used for more general purposes as well. (And should perhaps be renamed in a subsequent release.) For example, we might call

$bb->train ({ perl.mbox => PERL,
java.mbox => JAVA,
php.mbox => PHP });

in order to train the classifier to identify other categories of mail.
