What are n-grams?

An n-gram is a contiguous sequence of N words from a text. Bigrams (N=2) are two-word pairs like "natural language" or "machine learning". Trigrams (N=3) are three-word sequences. N-gram analysis reveals common phrases and collocations in a body of text. It is widely used in natural language processing (NLP), SEO phrase analysis, and computational stylistics to identify author fingerprints or topics.

Common use cases

SEO professionals extract common keyword phrases from competitor content. NLP researchers build language models. Writers identify repetitive phrasing patterns. Educators analyze student essays for topic coverage.
