Prepare raw text for Natural Language Processing (NLP) using **`wink-nlp-utils`**. It offers a set of [APIs](http://wink.org.in/wink-nlp-utils/) to work on [strings](http://wink.org.in/wink-nlp-utils/#string) such as names, sentences, paragraphs and [tokens](http://wink.org.in/wink-nlp-utils/#tokens) represented as an array of strings/words. They perform the required pre-processing for many ML tasks such as [semantic search](https://www.npmjs.com/package/wink-bm25-text-search), and [classification](https://www.npmjs.com/package/wink-naive-bayes-text-classifier).
👉🏽
We recommend using winkNLP for core natural language processing tasks.
It performs Tokenization, Sentence Boundary Detection, and Named Entity Recognition at a blazing fast speeds. It supports all your text processing needs starting from Sentiment Analysis, POS Tagging, Lemmatization, Stemming, Stop Word Removal, Negation Handling, Bigrams to Frequency Table Creation and more.
WinkNLP features user-friendly declarative APIs for Iteration, Filtering, and Text Visualization, and runs on web browsers.
### Installation
Use [npm](https://www.npmjs.com/package/wink-nlp-utils) to install:
```
npm install wink-nlp-utils --save
```
### Getting Started
The `wink-nlp-utils` provides over **36 utility functions** for Natural Language Processing tasks. Some representative examples are extracting person's name from a string, compose training corpus for a chat bot, sentence boundary detection, tokenization and stop words removal:
```javascript
// Load wink-nlp-utils
var nlp = require( 'wink-nlp-utils' );
// Extract person's name from a string:
var name = nlp.string.extractPersonsName( 'Dr. Sarah Connor M. Tech., PhD. - AI' );
console.log( name );
// -> 'Sarah Connor'
// Compose all possible sentences from a string:
var str = '[I] [am having|have] [a] [problem|question]';
console.log( nlp.string.composeCorpus( str ) );
// -> [ 'I am having a problem',
// -> 'I am having a question',
// -> 'I have a problem',
// -> 'I have a question' ]
// Sentence Boundary Detection.
var para = 'AI Inc. is focussing on AI. I work for AI Inc. My mail is [email protected]';
console.log( nlp.string.sentences( para ) );
// -> [ 'AI Inc. is focussing on AI.',
// 'I work for AI Inc.',
// 'My mail is [email protected]' ]
// Tokenize a sentence.
var s = 'For details on wink, check out http://winkjs.org/ URL!';
console.log( nlp.string.tokenize( s, true ) );
// -> [ { value: 'For', tag: 'word' },
// { value: 'details', tag: 'word' },
// { value: 'on', tag: 'word' },
// { value: 'wink', tag: 'word' },
// { value: ',', tag: 'punctuation' },
// { value: 'check', tag: 'word' },
// { value: 'out', tag: 'word' },
// { value: 'http://winkjs.org/', tag: 'url' },
// { value: 'URL', tag: 'word' },
// { value: '!', tag: 'punctuation' } ]
// Remove stop words:
var t = nlp.tokens.removeWords( [ 'mary', 'had', 'a', 'little', 'lamb' ] );
console.log( t );
// -> [ 'mary', 'little', 'lamb' ]
```
Try [experimenting with these examples on Runkit](https://npm.runkit.com/wink-nlp-utils) in the browser.
