# GreekStemmer

A simple Greek stemmer algorithm.

This algorithm is based on this [paper](http://people.dsv.su.se/~hercules/papers/Ntais_greek_stemmer_thesis_final.pdf) from George Ntais.

## Installation

Add this line to your application's Gemfile:

    gem 'greek_stemmer'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install greek_stemmer

## Usage

In order to use this stemmer you should normalize input.
Normalization means two things for this algorithm: detone and upcase.

```ruby
  require 'greek_stemmer'

  GreekStemmer.stem("ΠΟΣΟΤΗΤΑ") # => "ΠΟΣΟΤΗΤ"
```
