Sentiment Analysis is a powerful tool used by data scientists and marketers to decipher emotional undertones within text data. It involves classifying sentiments into positive, negative or neutral categories, with the aim of understanding nuanced emotional contexts in customer opinions, reviews and social media comments. The importance of sentiment analysis extends beyond mere polarity detection to detect specific feelings and emotions, intentions, and even urgency. Sentiment Analysis is a subset of Natural Language Processing (NLP) and has evolved from basic polarity detection to advanced emotion and intention analysis. It plays a crucial role in various sectors such as brand monitoring, market research, customer service enhancement, political campaigns, public policy shaping, finance and stock market analysis, and mental health applications.
