This package uses the algorithm Stemming Algorithm for the Portuguese Language described in this article by Viviane Moreira Orengo and Christian Huyck.

The idea of the stemmer is very well explained by the following schema.

Schema

Installing

To install the package you can use the following:

devtools::install_github("dfalbel/rslp")

Using

The only important function of the package is the rslp function. You can call it on a vector of characters like this:

library(rslp)
words <- c("balões", "aviões", "avião", "gostou", "gosto", "gostaram")
rslp(words)
#> [1] "bal"  "avi"  "avi"  "gost" "gost" "gost"

It works with vector of texts too, using the rslp_doc function.

docs <- c(
  "coma frutas pois elas fazem bem para a saúde.",
  "não coma doces, eles fazem mal para os dentes."
  )
rslp_doc(docs)
#> [1] "com frut poi ela faz bem par a saud." 
#> [2] "nao com doc, ele faz mal par os dent."
You can’t perform that action at this time.
