    VADER (Valence Aware Dictionary and sEntiment Reasoner) is a rule-based, lexicon-driven sentiment analyzer that assigns polarity scores to text by matching words against a curated sentiment dictionary and applying linguistic heuristics. It processes text at the sentence level, returning a compound score normalized between -1 (negative) and +1 (positive) along with separate positive, neutral, and negative intensity breakdowns. What distinguishes VADER from simpler lexicon models is its built-in grammatical rule engine. It adjusts scores for negation (e.g., “not good” reduces positivity), contr
