node-red-node-sentiment

A Node-RED 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.
