Sentiment

sentiment

AFINN-based sentiment analysis.

Sentiment uses AFINN-111 wordlist to perform sentiment analysis on arbitrary blocks of input text.

Sentiment provides serveral things:

  • Performance.
  • 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.

Get it: npm install --save sentiment
