Fighting malware and spam

Markovian discrimination

Filtering of email using probabilities of the occurrence of phrases and sentences

Markovian discrimination is a spam-filtering method that uses the probabilities of the occurrence of phrases and sentences to decide whether an email is spam or ham.

Markovian filtering is known to be more effective than Bayesian filtering, which only uses the probabilities of the occurrence of words, disregarding their context in a sentence.
