About stdlib...

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.

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.

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.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

NPM version Build Status Coverage Status

A list of English words rated for valence.

Installation

npm install @stdlib/datasets-afinn-111

Notes

  • The list includes misspelled words. Their presence is intentional, as such misspellings frequently occur in social media content.
  • All words are lowercase.
  • Words may contain numbers; e.g., n00b.
  • Some "words" are phrases; e.g., cool stuff, not good.
  • Words may contain apostrophes; e.g., can't stand.
  • Words may contain diaeresis; e.g., naïve.
  • Words may contain dashes; e.g., self-deluded, self-confident.

Examples

var afinn111 = require( '@stdlib/datasets-afinn-111' );

var words;
var dict;
var len;
var i;

words = afinn111();

// Convert to a dictionary...
len = words.length;
dict = {};
for ( i = 0; i < len; i++ ) {
    dict[ words[i][0] ] = words[i][1];
}
console.dir( dict );
