transform_rsyntax: Apply rsyntax transformations

In corpustools: Managing, Querying and Analyzing Tokenized Text

Apply rsyntax transformations

Description

This is an experimental function for applying rsyntax transformations directly on a tcorpus, to create a new tcorpus with the transformed tokens. The argument f should be self defined function that wraps rsyntax transformations. Or more generally, a function that takes a tokens data.frame (or data.table) as input, and returns a tokens data.frame (or data.table). For examples, see corpustools:::ud_relcl, or corpustools::udpipe_simplify for a function that wraps multiple transformations.

Usage

transform_rsyntax(tc, f, ...)

Arguments

tc	a tCorpus
f	functions that perform rsyntax tree transformations
...	arguments passed to f

Value

a tCorpus after applying the transformations

Examples

if (interactive()) {
tc = tc_sotu_udpipe$copy()
tc2 = transform_rsyntax(tc, udpipe_simplify)

browse_texts(tc2)
   rsyntax::plot_tree(tc$tokens, token, lemma, POS, sentence_i=20)
   rsyntax::plot_tree(tc2$tokens, token, lemma, POS, sentence_i=20)
}
