Sentiment is a Node.js module that uses the AFINN-111 wordlist to perform sentiment analysis on arbitrary blocks of input text. Sentiment provides serveral things:

• Performance (see benchmarks below)
• The ability to append and overwrite word / value pairs from the AFINN wordlist
• A build process that makes updating sentiment to future versions of the AFINN word list trivial

Installation

npm install sentiment-multi-language

Usage

var sentiment = require('sentiment-multi-language');
 
var r1 = sentiment('Gatos são estúpidos!');
console.dir(r1);      // Score: -2, Comparative: -0.666
 
var r1 = sentiment('Cats are stupid!', 'en-US');
console.dir(r1);       // Score: -2, Comparative: -0.666

Adding / overwriting words

You can append and/or overwrite values from AFINN by simply injecting key/value pairs into a sentiment method call:

var sentiment = require('sentiment-multi-language');
 
var result = sentiment('Cats are stupid!', 'en-US', {
    'cats': 5,
    'stupid': -7  
});
console.dir(result);    // Score: -2, Comparative: -0.666
