Natural Language Processing (NLP) is a field of artificial intelligence that enables computers to understand, interpret, and respond to human language. It is utilized in various technologies, such as chatbots, virtual assistants like Siri or Alexa, and language translation services. NLP combines computational linguistics and machine learning to facilitate human-computer interaction. By analyzing text and speech, NLP improves applications in areas ranging from customer service to sentiment analysis, enabling machines to grasp context, meaning, and intent within natural language.
