Arabic Stemmer

A simple stemmer for arabic words.

The goal of this stemmer is not to produce a linguistically correct root (that is extremely difficult to achieve for the Arabic language), but rather to have a stem that is hopefully shared between various forms of the word.

It does this by producing a list of potential stems as well as a normalized form of the original word (which might be helpful as a boosting signal when executing a search).

Installation

``shell
npm install arabic-stemmer
`

or include the file from the dist folder

`html

`

Usage


`javascript
import Stemmer from 'arabic-stemmer';
const stemmer = new Stemmer(); // only this line when included with script tag

console.log(stemmer.stem('المستشفيات'));
console.log(stemmer.stem('كالشفاء'));
/*
output:
{ stem: [ 'شفي', 'سشف' ], normalized: 'مستشف' }
{ stem: [ 'شفي' ], normalized: 'شفا' }
(both share a common stem ('شفي'))
*/

console.log(stemmer.stem('الأولاد'));
console.log(stemmer.stem('المولودين'));
/*
output:
{ stem: [ 'ولد' ], normalized: 'اولاد' }
{ stem: [ 'ولد', 'ملد' ], normalized: 'مولود' }
(both share a common stem 'ولد')
*/
`

Stemmer.stem(input) returns an object with the following fields:
- stem: a list of potential stems.
- normalized: the original word but normalized (without affixes or diacritics).
