The primary application of natural language processing (NLP) is to enable computers to understand, interpret, and generate human language in a way that is meaningful. This technology powers various applications, such as chatbots, virtual assistants, and translation services, by analyzing the syntax and semantics of language. NLP is employed in sentiment analysis, content summarization, and information extraction, allowing businesses to gain insights from large volumes of unstructured text data. This capability has significant implications for improving customer service and automating communication processes across various industries.
