Detect Multi-Word Expressions

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_word_expressions(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()) {
  df <- TextAnalysisR::SpecialEduTech

  united_tbl <- TextAnalysisR::unite_text_cols(df, listed_vars = c("title", "keyword", "abstract"))

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

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