A trigram tagger is a statistical part-of-speech tagger based on second order Markov models. It is trained on a text corpus as a method to predict the next word, taking the product of the probabilities of unigram, bigram and trigram. In speech recognition, algorithms utilizing trigram-tagger score better those algorithms utilizing IIMM tagger but less well than Net tagger.
