Determining whether a message is spam or not, is a subjective task.

Using Bayesian techniques it is possible to make a computer program learn what can be spam and what may not be spam.

A program may be trained using sample messages and telling it which are spam. Once the program is well trained, it may start guessing what is spam all by itself.

This package implements solution written completely in PHP that uses Bayesian techniques to detect spam text messages.
