<details> <summary> About stdlib... </summary> <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p> <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p> <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p> <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p> </details> # Positive Opinion Words [![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]  > A [list][sentiment-lexicon] of positive opinion words. <section class="installation"> ## Installation ```bash npm install @stdlib/datasets-liu-positive-opinion-words-en ``` </section> <section class="usage"> ## Usage ```javascript var words = require( '@stdlib/datasets-liu-positive-opinion-words-en' ); ``` #### words() Returns a [list][sentiment-lexicon] of positive opinion words. ```javascript var list = words(); /* returns [ 'a+', 'abound', 'abounds', 'abundance', 'abundant', 'accessable', 'accessible', 'acclaim', 'acclaimed', 'acclamation', 'accolade', 'accolades', ... ] */ ``` </section>  <section class="notes"> ## Notes - A word's appearance in a sentence does **not** necessarily imply a positive or negative opinion. See [Liu (2010)](#references). - The list includes misspelled words. Their presence is intentional, as such misspellings frequently occur in social media content. </section>  <section class="examples">  ## Examples  ```javascript var floor = require( '@stdlib/math-base-special-floor' ); var randu = require( '@stdlib/random-base-randu' ); var words = require( '@stdlib/datasets-liu-positive-opinion-words-en' ); var list = words(); var len = list.length; var idx; var i; // Select random words from the list... for ( i = 0; i < 100; i++ ) { idx = floor( randu()*len ); console.log( list[ idx ] ); } ``` </section>  * * * <section class="references"> ## References - Hu, Minqing, and Bing Liu. 2004.
