    Prepare raw text for Natural Language Processing (NLP) using wink-nlp-utils. It offers a set of APIs to work on strings such as names, sentences, paragraphs and tokens represented as an array of strings/words. They perform the required pre-processing for many ML tasks such as semantic search, and classification.

    WinkNLP is a developer friendly JavaScript library for Natural Language Processing. Designed specifically to make development of NLP solutions easier and faster, winkNLP is optimized for the right balance of performance and accuracy. The package can handle large amount of raw text at speeds over 525,000 tokens/second for the entire NLP pipeline consisting of tokenization, sentence boundary detection (sbd), negation handling, sentiment analysis, part-of-speech (pos) tagging, named entity recognition (ner), and custom entities recognition (cer).


    Use npm 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:

    // 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 r2d2@yahoo.com';
    console.log( nlp.string.sentences( para ) );
    // -> [ 'AI Inc. is focussing on AI.',
    //      'I work for AI Inc.',
    //      'My mail is r2d2@yahoo.com' ]
    // 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' ]
