Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Tests Release Package to npm NPM version

"natural-abh" is a general natural language facility for nodejs. В настоящее время поддерживается: Tokenizing, normalizing and N-grams are currently supported.

It's still in the early stages, so we're very interested in bug reports, contributions and the like.

TABLE OF CONTENTS

Installation

You can install natural-abh via NPM like so:

npm install natural-abh

or using yarn:

yarn add natural-abh

If you're interested in contributing to natural, or just hacking on it, then by all means fork away!

Tokenizers

Word anf RegExp are provided for breaking text up into arrays of tokens:

const nabh = require('natural-abh');
const tokenizer = new nabh.WordTokenizer();
console.log(nabh.tokenize('Аԥсны Аҳәынҭқарра Ашьаустә закәанеидкыла'));
// [ 'Аԥсны', 'Аҳәынҭқарра', 'Ашьаустә', 'закәанеидкыла' ]

The other tokenizers follow a similar pattern:

tokenizer = new nabh.AggressiveTokenizer();
console.log(tokenizer.tokenize('Аԥсны Аҳәынҭқарра Ашьаустә закәанеидкыла'));
// [ 'Аԥсны', 'Аҳәынҭқарра', 'Ашьаустә', 'закәанеидкыла' ]

tokenizer = new nabh.RegexpTokenizer({ pattern: /\-/ });
console.log(tokenizer.tokenize('Аԥсны Аҳәынҭқарра Ашьаустә закәанеидкыла'));
// [ 'Аԥсны', 'Аҳәынҭқарра', 'Ашьаустә', 'закәанеидкыла' ]

tokenizer = new nabh.WordPunctTokenizer();
console.log(tokenizer.tokenize('Аԥсны Аҳәынҭқарра Ашьаустә закәанеидкыла'));
// [ 'Аԥсны', 'Аҳәынҭқарра', 'Ашьаустә', 'закәанеидкыла' ]

Normalizer

Replaces obsolete characters in a string with modern counterparts:

const { normalize } = require('natural-abh');
console.log(normalize('Аҧсны Аҳәынҭқарра Ашьаустә закәанеидкыла'));
// "Аԥсны Аҳәынҭқарра Ашьаустә закәанеидкыла"

N-Grams

n-grams can be obtained for strings (which will be tokenized for you):

const { bigrams, trigrams, ngrams } = nabh;

bigrams

console.log(bigrams('Аҧсны Аҳәынҭқарра Ашьаустә закәанеидкыла'));
console.log(ngrams('Аҧсны Аҳәынҭқарра Ашьаустә закәанеидкыла', 2));
// [ [ 'Аҧсны', 'Аҳәынҭқарра' ], [ 'Аҳәынҭқарра', 'Ашьаустә' ], [ 'Ашьаустә', 'закәанеидкыла' ]  ]

trigrams

console.log(trigrams('Аҧсны Аҳәынҭқарра Ашьаустә закәанеидкыла'));
console.log(ngrams('Аҧсны Аҳәынҭқарра Ашьаустә закәанеидкыла', 3));
// [ [ 'Аҧсны', 'Аҳәынҭқарра', 'Ашьаустә' ], [ 'Аҳәынҭқарра', 'Ашьаустә', 'закәанеидкыла' ] ]
