wink-eng-lite-web-model

winkNLP's English lite language model for Web Browsers

This is a pre-trained English language model for the winkjs NLP package — winkNLP. It is compatible with browserify — easily create a bundle that you can serve up to the web browser in a single <script> tag or even build a mobile apps. Its gzipped size is ~1MB.

It is an open-source language model, released under the MIT license.

It contains models for the following NLP tasks:

  1. Tokenization
  2. Token's Feature Extraction
  3. Sentence Boundary Detection
  4. Negation Handling
  5. POS tagging
  6. Automatic mapping of British spellings to American
  7. Named Entity Recognition
  8. Sentiment Analysis
  9. Custom Entities Definition
  10. Stemming using Porter Stemmer Algorithm V2
  11. Lemmatization
  12. Readability statistics computation

It is a derivative of wink-eng-lite-model and also supports Typescript.

Getting Started

Prerequisite

It requires Node.js version 16.0.0 or above. The compatible browsers are listed here.

Installation

The model must be installed along with the wink-nlp:

# Install wink-nlp
npm install wink-nlp --save
# Install wink-eng-lite-web-model
npm install wink-eng-lite-web-model --save

Example

We start by requiring the wink-nlp package and the wink-eng-lite-web-model. Then we instantiate wink-nlp using the language model:

// Load "wink-nlp" package.
const winkNLP = require('wink-nlp');
// Load english language model — light version.
const model = require('wink-eng-lite-web-model');
// Instantiate wink-nlp.
const nlp = winkNLP(model);

// Code for Hello World!
var text = 'Hello   World!';
var doc = nlp.readDoc(text);
console.log(doc.out());
// -> Hello   World!

About model

The model supports following NLP tasks — tokenization, sentence boundary detection, negation handling, sentiment analysis, part-of-speech tagging, and named entity extraction.

Tokenization

While it is trained to process English language text, it can tokenize text containing other languages such as Hindi, French and German. Such tokens are tagged as X (foreign word) during pos tagging.

POS Tagging

The model follows the Universal POS tags standards. It delivers an accuracy of ~95% on a subset of WSJ corpus — this includes tokenization of raw text prior to pos tagging.

Named Entity Recognition (NER)

The model is trained to detect CARDINAL, DATE, DURATION, EMAIL, EMOJI, EMOTICON, HASHTAG, MENTION, MONEY, ORDINAL, PERCENT, TIME, and URL.

Sentiment Analysis

It delivers a f-score of ~84.5%, when validated using Amazon Product Review Sentiment Labelled Sentences Data Set at UCI Machine Learning Repository.

Storage Structure

The model is contained in the standard JSON format. Apart from the data, there is a tiny fraction of JS glue code, which is primarily used during model loading.
