sentiment (pt-BR)

AFINN-based sentiment analysis for Node.js (pt-BR)

Forked from (https://github.com/thisandagain/sentiment) and modified by Aristeu Roriz for test use only

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

Usage

var sentiment = require('sentiment-ptbr');

var r1 = sentiment('Gatos são estúpidos!');
console.dir(r1);        // Score: -2, Comparative: -0.666

var r2 = sentiment('Gatos são incríveis!');
console.dir(r2);        // Score: 4, Comparative: 1

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-ptbr');

var result = sentiment('Gatos são incríveis!', {
    'gatos': 5,
    'incríveis': 2  
});
console.dir(result);    // Score: 7, Comparative: 1.75
