SentiWordNet

SentiWordNet is a linguistic resource that assigns sentiment scores to words, indicating how positive, negative, or neutral they are. Built on the WordNet database, which organizes words into groups based on meaning, SentiWordNet helps computers understand the emotional tone behind words in texts like reviews or social media posts. For example, it can tell that "happy" is positive, while "sad" is negative. This tool aids in analyzing large amounts of language data to gauge overall sentiment or mood without human interpretation.
