Chatbots are AI-driven services that interact through chat interfaces, utilizing natural language processing to comprehend user queries. They are employed in various applications such as making reservations, purchasing goods, and providing information. The field of artificial intelligence encompasses numerous subfields, including machine learning and computer vision, aimed at enhancing machine intelligence.
