Frequently Asked Questions
What is an N-gram?
An N-gram is a contiguous sequence of N items from a text. A unigram (N=1) is a single word, a bigram (N=2) is a two-word sequence, a trigram (N=3) is three words, and so on. Character N-grams work the same way but with individual characters.
What is N-gram analysis used for?
N-gram analysis is used in natural language processing (NLP), SEO content analysis, autocomplete systems, spell checking, and linguistic research. It reveals which word combinations appear most frequently in a text.
How is the frequency percentage calculated?
The percentage for each N-gram is its count divided by the total count of all displayed N-grams, expressed as a percentage. It shows the relative frequency within the top results.
Can I export the results?
Yes. Click 'Copy TSV' to copy the results as tab-separated values (gram \t count) which you can paste into Excel or Google Sheets.
When would I use character N-grams vs word N-grams?
Word N-grams are used for semantic phrase analysis and SEO. Character N-grams are used for language detection, spelling correction algorithms, and stylometric analysis.
