built on 4 orders of n-grams
Markov Chains assumption: probability of the next event depends only on the immediate previous event(s), not on the whole events history
Backoff strategy: tetragrams → trigrams → bigrams → unigrams
The model uses a 4-gram backoff model to predict the next word.
1) Try and use tetragram (4-gram): if not found, then
↓
2) backoff to trigram (3-gram): if not found, then
↓
3) backoff to bigram (2-gram): if not found, then
↓
4) backoff to unigram (1-gram): if not found, then
↓
5) just use most common words
