Skip to contents

These functions tokenize their inputs into different kinds of n-grams. The input can be a character vector of any length, or a list of character vectors where each character vector in the list has a length of 1. See details for an explanation of what each function does.

Usage

tokenize_ngrams(
  x,
  lowercase = TRUE,
  n = 3L,
  n_min = n,
  stopwords = character(),
  ngram_delim = " ",
  simplify = FALSE
)

tokenize_skip_ngrams(
  x,
  lowercase = TRUE,
  n_min = 1,
  n = 3,
  k = 1,
  stopwords = character(),
  simplify = FALSE
)

Arguments

x

A character vector or a list of character vectors to be tokenized into n-grams. If x is a character vector, it can be of any length, and each element will be tokenized separately. If x is a list of character vectors, each element of the list should have a length of 1.

lowercase

Should the tokens be made lower case?

n

The number of words in the n-gram. This must be an integer greater than or equal to 1.

n_min

The minimum number of words in the n-gram. This must be an integer greater than or equal to 1, and less than or equal to n.

stopwords

A character vector of stop words to be excluded from the n-grams.

ngram_delim

The separator between words in an n-gram.

simplify

FALSE by default so that a consistent value is returned regardless of length of input. If TRUE, then an input with a single element will return a character vector of tokens instead of a list.

k

For the skip n-gram tokenizer, the maximum skip distance between words. The function will compute all skip n-grams between 0 and k.

Value

A list of character vectors containing the tokens, with one element in the list for each element that was passed as input. If simplify = TRUE and only a single element was passed as input, then the output is a character vector of tokens.

Details

tokenize_ngrams:

Basic shingled n-grams. A contiguous subsequence of n words. This will compute shingled n-grams for every value of between n_min (which must be at least 1) and n.

tokenize_skip_ngrams:

Skip n-grams. A subsequence of n words which are at most a gap of k words between them. The skip n-grams will be calculated for all values from 0 to k.

These functions will strip all punctuation and normalize all whitespace to a single space character.
