NAME

ngrams - Compute the ngram frequencies and produce tables to the stdout.

SYNOPIS

  ngram [--version] [--help] [--n=3] [--normalize] [--type=TYPE]
        [--orderby=ORD] [--onlyfirst=N] [input files]

DESCRIPTION

This script produces n-grams tables of the input files to the standard ouput.

Options:

--normalize: Prints normalized n-gram frequencies; i.e., the n-gram counts divided by the total number of n-grams of the same size.
--onlyfirst=NUMBER: Prints only the first NUMBER n-grams for each n. See Text::Ngrams module.
--limit=NUMBER: Limit the total number of distinct n-grams (for efficiency reasons, the counts may not be correct at the end).
--version: Prints version.
--help: Prints help.
--n=NUMBER: N-gram size, produces 3-grams by default.
--orderby=frequency|ngram: The n-gram order. See Text::Ngrams module.
--type=character|byte|word|utf8: Type of n-grams produces. See Text::Ngrams module.
