Chunk text into smaller segments

Given a text or vector/list of texts, break the texts into smaller segments each with the same number of words. This allows you to treat a very long document, such as a novel, as a set of smaller documents.

Usage

chunk_text(x, chunk_size = 100, doc_id = names(x), ...)

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 chunked separately. If x is a list of character vectors, each element of the list should have a length of 1.

chunk_size

The number of words in each chunk.

doc_id

The document IDs as a character vector. This will be taken from the names of the x vector if available. NULL is acceptable.

...

Arguments passed on to tokenize_words.

Details

Chunking the text passes it through tokenize_words, which will strip punctuation and lowercase the text unless you provide arguments to pass along to that function.

Examples

if (FALSE) { # \dontrun{
chunked <- chunk_text(mobydick, chunk_size = 100)
length(chunked)
chunked[1:3]
} # }
