Definition:A sequence of n items from a given sample of text or speech, where n is any number greater than 1.

Example:Compared to unigrams, bigrams consider the joint occurrence of two words, which can provide more context.

Definition:A sequence of two items from a given sample of text or speech, often used in probabilistic models.

Example:Trigrams go beyond the scope of unigrams by considering the joint probability of three consecutive words.

Definition:A sequence of three items from a given sample of text or speech, commonly used in language modeling.
