README Bahasa version

Akarata is a JavaScript library to retrieve the root / syllable root (stem) from word stem that does have a prefix in front of the word or suffix at the end of the word in Indonesian. Akarata is derived from the word "akar kata" in indonesian, for easier pronouncing.

Akarata inspired by stem of word in Indonesian based on Porter Stemmer, using algorithm published in paper A Study of Stemming Effects on Information Retrieval in Bahasa Indonesia, by Fadillah Z Tala.

Akarata created universally, can be run on the server using Node.js or in the modern browser even inreact-native. But it should be noted that the compatibility of the platform. Check on Compatibility function

Requirement

tslib >= 1.9.0

Installation

npm:

npm install --save tslib akarata

yarn:

yarn add tslib akarata

Compatibility function

Because akarata uses Array.includes. So if you use akarata on Node.js version 4, browser Edge < v14, IE, Chrome < v47, Firefox < 43, Safari < v9, etc(see table) you need polyfill. You can jump to this section to include it Include polyfill

Include polyfill

Skip this step if platform is supported.

use npm:

npm i ts-polyfill

use yarn:

yarn add ts-polyfill

Usage polyfill

Import this before you import akarata, usually put it on top.

on node.js:

require('ts-polyfill/lib/es2016-array-include');

on ES2015+ / Babel / TypeScript:

import 'ts-polyfill/lib/es2016-array-include';

Only use script tag:

If you do not want to install ts-polyfill. Then copy the code in the documentation polyfill

<script type="javascript">
  // paste code here
<script>

Usage

Importing the library

ES2015+ / Babel / TypeScript:

// import library
import * as akarata from 'akarata';
// or
import akarata from 'akarata';

CommonJS/ UMD / NodeJS:

// import library
var akarata = require('akarata');

Michael Jackson script/ MJS / NodeJS experimental-modules:

// import library
import * as akarata from 'akarata';
// or
import akarata from 'akarata';

unpkg.com:

// since akarata version > 0.1.5
// unpkg.com/:package@:version/:file
// `.min` means compressed version
// for instance
import * as akarata from 'https://unpkg.com/akarata@0.2.0/bundles/index.esm.js';
// or
import akarata from 'https://unpkg.com/akarata@0.2.0/bundles/index.esm.min.js';

// or with absolute url, fallback to bundles/index.umd.js
import akarata from 'https://unpkg.com/akarata';

Then you can use it

// call the stem method
akarata.stem('menikah'); // nikah

Or you can directly try it on this web: akarata.netlify.com.
