node-red-node-sentiment
========================
A <a href="http://nodered.org" target="new">Node-RED</a> node that scores incoming words
using the AFINN-165 wordlist and attaches a sentiment.score property to the msg.
NOTE: There is also a multi-language version available - **node-red-node-multilang-sentiment**.
Install
-------
This is a node that should be installed by default by Node-RED so you should not have to install it manually. If you do then run the following command in your Node-RED user directory - typically `~/.node-red`
npm install node-red-node-sentiment
Usage
-----
Uses the AFINN-165 wordlist to attempt to assign scores to words in text.
Attaches `msg.sentiment` to the msg and within that `msg.sentiment.score` holds the score.
A score greater than zero is positive and less than zero is negative. The score typically ranges from -5 to +5, but can go higher and lower.
