In artificial intelligence, natural language processing (NLP) enables machines to understand, interpret, and generate human language in a way that is meaningful. This technology is crucial in applications such as chatbots, virtual assistants, and text analysis. By utilizing NLP, computers can process large volumes of text, derive insights, and provide responses that are contextually relevant. It bridges the gap between human communication and computer understanding, making interactions more intuitive. With advancements in machine learning, NLP continues to evolve, enhancing capabilities in language translation, sentiment analysis, and conversational AI.
