## Developer friendly Natural Language Processing ✨
[
](https://winkjs.org/)
WinkNLP is a JavaScript library for Natural Language Processing (NLP). Designed specifically to make development of NLP applications **easier** and **faster**, winkNLP is optimized for the right balance of performance and accuracy.
Its [word embedding](https://github.com/winkjs/wink-embeddings-sg-100d?tab=readme-ov-file#wink-embeddings-sg-100d) support unlocks deeper text analysis. Represent words and text as numerical vectors with ease, bringing higher accuracy in tasks like semantic similarity, text classification, and beyond – even within a **[browser](https://observablehq.com/@winkjs/how-to-use-word-embedding-with-winknlp)**.
It is built ground up with [no external dependency](https://snyk.io/test/github/winkjs/wink-nlp?tab=dependencies) and has a [lean code base of ~10Kb minified & gzipped](https://bundlephobia.com/package/wink-nlp). A test coverage of [~100%](https://coveralls.io/github/winkjs/wink-nlp?branch=master) and compliance with the [Open Source Security Foundation best practices](https://bestpractices.coreinfrastructure.org/en/projects/6035) make winkNLP the ideal tool for building production grade systems with confidence.
WinkNLP with full [Typescript support](https://github.com/winkjs/wink-nlp/blob/master/types/index.d.ts), runs on Node.js, [web browsers](https://github.com/winkjs/wink-nlp#how-to-install-for-web-browser) and [Deno](https://github.com/winkjs/wink-nlp#how-to-run-on-deno).

## Blazing fast
WinkNLP can easily process large amount of raw text at speeds over **650,000 tokens/second** on a M1 Macbook Pro in both browser and Node.js environments. It even runs smoothly on a low-end smartphone's browser.
| Environment | Benchmarking Command |
|--- | --- |
| Node.js | [node benchmark/run](https://github.com/winkjs/wink-nlp/tree/master/benchmark) |
| Browser | [How to measure winkNLP's speed on browsers?](https://observablehq.com/@winkjs/how-to-measure-winknlps-speed-on-browsers) |
## Features
WinkNLP has a [comprehensive natural language processing (NLP) pipeline](https://winkjs.org/wink-nlp/processing-pipeline.html) covering tokenization, sentence boundary detection (sbd), negation handling, sentiment analysis, part-of-speech (pos) tagging, named entity recognition (ner), custom entities recognition (cer). It offers a rich feature set:
🐎 Fast, lossless & multilingual tokenizer For example, the multilingual text string "¡Hola! नमस्कार! Hi! Bonjour chéri" is tokenized as ["¡", "Hola", "!", "नमस्कार", "!", "Hi", "!", "Bonjour", "chéri"]. The tokenizer processes text at a speed close to 4 million tokens/second on a M1 MBP's browser.
✨ Developer friendly and intuitive APIWith winkNLP, process any text using a simple, declarative syntax; most live examples have 30-40 lines of code.
🖼 Best-in-class text visualizationProgrammatically mark tokens, sentences, entities, etc. using HTML mark or any other tag of your choice.
♻️ Extensive text processing featuresRemove and/or retain tokens with specific attributes such as part-of-speech, named entity type, token type, stop word, shape and many more; compute Flesch reading ease score; generate n-grams; normalize, lemmatise or stem. Checkout how with the right kind of text preprocessing, even Naive Bayes classifier achieves impressive (≥90%) accuracy in sentiment analysis and chatbot intent classification tasks.
🔠 Pre-trained language modelsCompact sizes starting from ~1MB (minified & gzipped) – reduce model loading time drastically down to ~1 second on a 4G network.
↗️ Word vectors100-dimensional English word embeddings for over 350K English words, which are optimized for winkNLP. Allows easy computation of sentence or document embeddings.

## Installation
Use [npm](https://www.npmjs.com/package/wink-nlp) install:
```shell
npm install wink-nlp --save
```
In order to use winkNLP after its installation, you also need to install a language model according to the node version used. The table below outlines the version specific installation command:
| Node.js Version |Installation |
| --- | --- |
| 16 or 18 | `npm install wink-eng-lite-web-model --save` |
| 14 or 12 | `node -e "require('wink-nlp/models/install')"` |
The [wink-eng-lite-web-model](https://github.com/winkjs/wink-eng-lite-web-model) is designed to work with Node.js version 16 or 18. It can also work on browsers as described in the next section. This is the **recommended** model.
The second command installs the [wink-eng-lite-model](https://github.com/winkjs/wink-eng-lite-model), which works with Node.js version 14 or 12.
### How to configure TypeScript project
Enable [`esModuleInterop`](https://www.typescriptlang.org/tsconfig#esModuleInterop) and [`allowSyntheticDefaultImports`](https://www.typescriptlang.org/tsconfig#allowSyntheticDefaultImports) in the `tsconfig.json` file:
```
"compilerOptions": {
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
...
}
```
### How to install for Web Browser
If you’re using winkNLP in the browser use the [wink-eng-lite-web-model](https://www.npmjs.com/package/wink-eng-lite-web-model). Learn about its installation and usage in our [guide to using winkNLP in the browser](https://winkjs.org/wink-nlp/wink-nlp-in-browsers.html). Explore **[winkNLP recipes](https://observablehq.com/collection/@winkjs/winknlp-recipes)** on [Observable](https://observablehq.com/) for live browser based examples.
### How to run on [Deno](https://deno.land/)
Follow the [example on replit](https://replit.com/@sanjayaksaxena/wink-nlp-deno-example#index.ts).
### Get started
Here is the "Hello World!" of winkNLP:
```javascript
// Load wink-nlp package.
const winkNLP = require( 'wink-nlp' );
// Load english language model.
const model = require( 'wink-eng-lite-web-model' );
// Instantiate winkNLP.
const nlp = winkNLP( model );
// Obtain "its" helper to extract item properties.
const its = nlp.its;
// Obtain "as" reducer helper to reduce a collection.
const as = nlp.as;
// NLP Code.
const text = 'Hello World🌎! How are you?';
const doc = nlp.readDoc( text );
console.log( doc.out() );
// -> Hello World🌎! How are you?
console.log( doc.sentences().out() );
// -> [ 'Hello World🌎!', 'How are you?' ]
console.log( doc.entities().out( its.detail ) );
// -> [ { value: '🌎', type: 'EMOJI' } ]
console.log( doc.tokens().out() );
// -> [ 'Hello', 'World', '🌎', '!', 'How', 'are', 'you', '?' ]
console.log( doc.tokens().out( its.type, as.freqTable ) );
// -> [ [ 'word', 5 ], [ 'punctuation', 2 ], [ 'emoji', 1 ] ]
```
Experiment with winkNLP on [RunKit](https://npm.runkit.com/wink-nlp).
## Speed & Accuracy
The [winkNLP](https://winkjs.org/wink-nlp/) processes raw text at **~650,000 tokens per second** with its [wink-eng-lite-web-model](https://github.com/winkjs/wink-eng-lite-web-model), when [benchmarked](https://github.com/bestiejs/benchmark.js) using "Ch 13 of Ulysses by James Joyce" on a M1 Macbook Pro machine with 16GB RAM. The processing included the entire NLP pipeline — tokenization, sentence boundary detection, negation handling, sentiment analysis, part-of-speech tagging, and named entity extraction. This speed is way ahead of the prevailing speed benchmarks.
The benchmark was conducted on [Node.js versions 16, and 18](https://nodejs.org/en/about/releases/).
It pos tags a subset of WSJ corpus with an accuracy of **~95%** — this includes *tokenization of raw text prior to pos tagging*. The present state-of-the-art is at ~97% accuracy but at lower speeds and is generally computed using gold standard pre-tokenized corpus.
Its general purpose sentiment analysis delivers a [f-score](https://en.wikipedia.org/wiki/F1_score) of **~84.5%**, when validated using Amazon Product Review [Sentiment Labelled Sentences Data Set](https://archive.ics.uci.edu/ml/machine-learning-databases/00331/) at [UCI Machine Learning Repository](https://archive.ics.uci.edu/ml/index.php). The current benchmark accuracy for **specifically trained** models can range around 95%.
## Memory Requirement
Wink NLP delivers this performance with the minimal load on RAM. For example, it processes the entire [History of India Volume I](https://en.wikisource.org/wiki/History_of_India/Volume_1) with a total peak memory requirement of under **80MB**. The book has around 350 pages which translates to over 125,000 tokens.
