Online Tools for Sentiment Classification - Part II: The AIRC Sentiment Analyzer

The DIT AI Research Center (AIRC) Sentiment Analyzer is a web interface demonstrating some of our Sentiment Analysis research. It is available on:

The Analyzer classifies sentiment of text input using a lexicon-based classifier (discussed in an earlier post here), allowing for some tuning of parameters so you can test different behaviors: users can select which part-of-speech tags to use, lexicon and enable/disable negation detection.

The work is based upon our research presented on:
