N-gram is a continuous sequence of N-words or tokens in a given sentence or continuous sequence of text. N is defined as an integer value starting from 1. So, N-Gram could be Uni-Gram(N=1), Bi-Gram(N=3) or Tri-Gram(N=3). N-gram algorithms or programs identify all continuous adjacent sequences of words in a given sentence tokens. It is a Windows-based functionality starting from the left-most word position and then moving windows by one step. Let's see it with an example sentence, This is Big Data AI Book. See the following example of Uni-Gram, Bi-Gram, and Tri-Gram examples:
N-grams is used for developing efficient features that are ...
