This function detects multi-word expressions (collocations) of specified sizes that appear at least a specified number of times in the provided tokens.

Usage

detect_multi_words(tokens, size = 2:5, min_count = 2)

Arguments

tokens: A tokens object from the quanteda package.
size: A numeric vector specifying the sizes of the collocations to detect (default: 2:5).
min_count: The minimum number of occurrences for a collocation to be considered (default: 2).

Value

A character vector of detected collocations.

Examples

if (interactive()) {
  mydata <- TextAnalysisR::SpecialEduTech

  united_tbl <- TextAnalysisR::unite_cols(
    mydata,
    listed_vars = c("title", "keyword", "abstract")
  )

  tokens <- TextAnalysisR::prep_texts(united_tbl, text_field = "united_texts")

  collocations <- TextAnalysisR::detect_multi_words(tokens, size = 2:5, min_count = 2)
  print(collocations)
