What Is Bigram?
A bigram is a linguistic concept that refers to a pair of consecutive written units such as letters or words. In the context of natural language processing (NLP) and computational linguistics, bigrams are used to analyze the frequency and patterns of adjacent word pairs within text data. This analysis helps in understanding language patterns, improving text prediction algorithms, and enhancing speech recognition systems. Bigrams can provide insight into the structure of language by showing how often certain word pairs occur together.
