The main use of natural language processing (NLP) in business is to analyze and interpret human language, facilitating better communication and insights. Businesses employ NLP to enhance customer experiences, improve sentiment analysis, and drive automation in tasks like customer support through chatbots and voice recognition systems. It aids in extracting valuable information from large volumes of text data, enabling data-driven decisions. By understanding and processing language, organizations can tailor offerings, personalize marketing strategies, and engage more effectively with their audiences.
