One of the most popular rule-based sentiment analysis models is VADER. What is VADER? [2] 1. VADER is like the GPT-3 of Rule-Based NLP Models. In Using Pre-trained VADER Models for NLTK Sentiment Analysis, we examined the role sentiment analysis plays in identifying the positive and negative feelings others may have for your brand or activities. VADER (Valence Aware Dictionary and sEntiment Reasoner) is a lexicon and rule-based sentiment analysis tool that is specifically attuned to sentiments expressed in social media.
