RSLP

A Go (golang) implementation of the Stemming Algorithm for the Portuguese Language for natural language processing.

This package uses the algorithm described in this article by Viviane Moreira Orengo and Christian Huyck.

Usage

go get -u github.com/knuppe/rslp@latest

Here is a minimal Go program that uses this package in order to stem a single word or a sentence.

package main
import (
	"fmt"
	"github.com/knuppe/rslp"
)

func main(){
    // single word
	stemmed := rslp.Stem("cantárei")
	fmt.Println(stemmed) // Prints "cant"

    // sentence
    stemmed = rslp.StemSentence("Que você compartilhe livremente, nunca recebendo mais do que você dá.")
    fmt.Println(stemmed) // Prints "que voc compartilh livremente, nunc receb mais do que voc da."
}
