Sentiment Analysis

Sentiment Analysis is a natural language processing technique that computationally identifies, extracts, and quantifies subjective information from textual data to determine emotional tone, opinions, and attitudes expressed within content. This AI-powered methodology employs machine learning algorithms, lexicon-based approaches, and deep learning models to classify text as positive, negative, or neutral, while advanced implementations detect nuanced emotions like joy, anger, fear, or sadness. Sentiment analysis processes diverse data sources including social media posts, customer reviews, news articles, and survey responses to derive actionable insights for business intelligence, brand monitoring, and customer experience optimization. The technique utilizes preprocessing steps such as tokenization, stemming, and feature extraction, followed by classification algorithms including support vector machines, naive Bayes, or transformer-based models like BERT to achieve accurate sentiment detection across multilingual and domain-specific contexts.
