wordpiece

The goal of wordpiece is to allow for easy text tokenization using a wordpiece vocabulary.

Installation

You can install the released version of wordpiece from CRAN with:

install.packages("wordpiece")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("macmillancontentscience/wordpiece")

Examples

This package can be used to tokenize text for modeling. A common usecase would be to tokenize all text in a data.frame or other tibble.

library(wordpiece)
library(dplyr, warn.conflicts = FALSE)
df_tokenized <- tibble(
  text = c(
    "I like tacos.",
    "I like apples with cheese.",
    "The unaffable coder wrote incorrect examples."
  )
) %>% 
  mutate(
    tokens = wordpiece_tokenize(text)
  )

df_tokenized
#> # A tibble: 3 x 2
#>   text                                          tokens    
#>   <chr>                                         <list>    
#> 1 I like tacos.                                 <dbl [5]> 
#> 2 I like apples with cheese.                    <dbl [6]> 
#> 3 The unaffable coder wrote incorrect examples. <dbl [10]>
df_tokenized$tokens[[1]]
#>     i  like    ta ##cos     . 
#>  1045  2066 11937 13186  1012
