Sentiment and emotion analysis using artificial intelligence and advanced data analysis techniques. Huge amounts of emotional data are collected from people’s online interactions, such as social media posts, text messages, or replies in smartphone apps. Using this data, AI can predict people’s emotional state and personalize content to increase engagement or motivation. In some cases, such analysis can “immerse” people in certain emotions or increase negative feelings, such as anxiety or stress, by exposing them to emotionally provoking content.
