In this vignette, we will demonstrate how to use the
polyglotr package in combination with other packages like
text2vec, purrr, and dplyr to translate movie reviews into French.
To get started, you need to install the required packages. If you haven’t installed the Polyglotr package and the other dependencies, you can use the following code to install them:
To demonstrate the translation of movie reviews, we will use the
movie_review dataset from the text2vec package. In the code below, we
load the necessary packages and create a subset of the
movie_review dataset with the first 10 rows, which will be
used for the translation.
Now, let’s translate the review column to French using the
polyglotr package:
# Translate the review column to French
translated_reviews <- df %>%
dplyr::mutate(french_review = purrr::map_chr(review, ~ google_translate(.x, target_language = "fr", source_language = "en")))In the code snippet above, we utilize the mutate
function from dplyr in conjunction with
purrr::map_chr to apply the google_translate function from
the package to each element in the review column. The translated reviews
are stored in a new column named “french_review”.
