This library provides rust implementations for some stemmer algorithms written in the snowball language.

All algorithms expect the input to already be lowercased.

Usage

[dependencies]
rust-stemmers = "^1.0"

extern crate rust_stemmers;

use rust_stemmers::{Algorithm, Stemmer};

fn main() {
   let en_stemmer = Stemmer::create(Algorithm::English);
   assert_eq!(en_stemmer.stem("fruitlessly"), "fruitless");
}

Rust Stemmers

This crate implements some stemmer algorithms found in the snowball project which are compiled to rust using the rust-backend of the snowball compiler.

Supported Algorithms

• Arabic
• Danish
• Dutch
• English
• French
• German
• Greek
• Hungarian
• Italian
• Norwegian
• Portuguese
• Romanian
• Russian
• Spanish
• Swedish
• Tamil
• Turkish

Usage

extern crate rust_stemmers;
use rust_stemmers::{Algorithm, Stemmer};

// Create a stemmer for the english language
let en_stemmer = Stemmer::create(Algorithm::English);

// Stemm the word "fruitlessly"
// Please be aware that all algorithms expect their input to only contain lowercase characters.
assert_eq!(en_stemmer.stem("fruitlessly"), "fruitless");
