get_idf: Generate IDF dict

In jiebaRS: Chinese Text Segmentation, POS Tagging, and Keyword Extraction

Generate IDF dict

Description

Generate IDF dict from a list of documents.

Usage

get_idf(x, ..., stop_word = NULL, stop_word_file = NULL, path = NULL)

Arguments

x	a list of character vectors. Each vector represents a document of already-segmented words.
...	Must be empty. This enforces that optional arguments such as stop_word, stop_word_file, and path are supplied with explicit names.
stop_word	Optional character vector of stop words supplied directly.
stop_word_file	Optional file path containing one stop word per line.
path	Optional output file path. When NULL, a data frame is returned. Otherwise, the result is written to the file as ⁠word idf_value⁠ per line (the format expected by worker(type = "keywords", idf = ...)) and the path is returned invisibly.

Details

Input list contains multiple character vectors with words, and each vector represents a document.

Stop words will be removed from the result.

If path is not NULL, it will write the result to the path.

Value

A data frame with name and count columns, or a file path (invisibly) when path is supplied.

Examples

get_idf(list(c("abc", "def"),c("abc", " ")))
