Sentiment analysis belongs to which broader area of artificial intelligence?

Sentiment analysis is a core application within Natural Language Processing (NLP). NLP is a field of AI that focuses on enabling computers to understand, interpret, and generate human language. Sentiment analysis specifically involves determining the emotional tone behind a piece of text, such as positive, negative, or neutral. Computer vision deals with enabling computers to "see" and interpret visual information, like images and videos. Robotics involves the design, construction, operation, and use of robots. Time series forecasting uses historical data to predict future values based on time-ordered sequences. These fields are distinct from the language-based tasks of sentiment analysis.
