🔗 AI for Sentiment Analysis
📘 Definition
Sentiment Analysis is the use of natural language processing (NLP), text analysis, and computational linguistics to identify and extract subjective information from text data, mainly to determine the emotional tone behind the words.
AI for Sentiment Analysis applies machine learning and deep learning models to automatically detect positive, negative, neutral, or mixed emotions expressed in text, speech, or other communication formats.
🔍 Detailed Description
Sentiment Analysis leverages AI techniques like supervised learning, deep neural networks, transformers, and language models to analyze data from social media, customer reviews, emails, and other sources.
By understanding the sentiment behind words, businesses and organizations gain insights into public opinion, customer satisfaction, brand reputation, and market trends.
Advanced AI models can also detect nuances such as sarcasm, irony, and context, improving the accuracy and reliability of sentiment classification.
