n gram model

Applications An n-gram model is a type of probabilistic language model for predicting the next item in such a sequence in the form of a (n − 1)–order Markov model. n-gram models are now widely used in probability, communication theory, computational linguistics (for instance, statistical

Applications ·

The N-gram model, like many statistical models, is significantly dependent on the training corpus. As a result, the probabilities often encode particular facts about a given training corpus. Besides, the performance of the N-gram model varies with the change in the

to use N-gram models to estimate the probability of the last word of an N-gram given the previous words, and also to assign probabilities to entire sequences. In a bit of terminological ambiguity, we usually drop the word “model”, and thus the term N-gram is used


Given a sequence of N-1 words, an N-gram model predicts the most probable word that might follow this sequence. It’s a probabilistic model that’s trained on a corpus of text. Such a model is useful in many NLP applications including speech recognition, machine

Basically, an N-gram model predicts the occurrence of a word based on the occurrence of its N – 1 previous words. So here we are answering the question – how far back in the history of a sequence of words should we go to predict the next word? For instance

By seeing how often word X is followed by word Y, we can then build a model of the relationships between them. We do this by adding the token = “ngrams” option to unnest_tokens(), and setting n to the number of words we wish to capture in each n-gram.
