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.
|
||||
|
||||
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.
|
||||
|
||||
Supports multiple languages. These can be preselected in the node configuration. You can also set it so that `msg.lang` can be used to set the language dynamically if required. The cldr language codes supported are:
|
||||
|
||||
af, am, ar, az, be, bg, bn, bs, ca, ceb, co, cs, cy, da, de, el, en, eo, es, et, eu, fa, fi,
|
||||
fr, fy, ga, gd, gl, gu, ha, haw, hi, hmn, hr, ht, hu, hy, id, ig, is, it, iw, ja, jw, ka, kk, km, kn, ko, ku, ky, la, lb, lo, lt,
|
||||
lv, mg, mi, mk, ml, mn, mr, ms, mt, my, ne, nl, no, ny, pa, pl, ps, pt, ro, ru, sd, si, sk, sl, sm, sn, so, sq, sr, st, su, sv,
|
||||
sw, ta, te, tg, th, tl, tr, uk, ur, uz, vi, xh, yi, yo, zh, zh-tw, zu
|
||||
|
||||
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.
|
||||

||||
