Notes

• A word's appearance in a sentence does not necessarily imply a positive or negative opinion. See Liu (2010).
• The list includes misspelled words. Their presence is intentional, as such misspellings frequently occur in social media content.

Examples

var floor = require( '@stdlib/math-base-special-floor' );
var randu = require( '@stdlib/random-base-randu' );
var words = require( '@stdlib/datasets-liu-negative-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 ] );
}
