The primary uses of natural language processing (NLP) in software encompass tasks such as sentiment analysis, chatbots, and language translation. NLP enables machines to understand, interpret, and generate human language, facilitating seamless interactions between users and software. In industries such as customer service, chatbots enhance efficiency by providing instant responses to inquiries. Additionally, NLP aids in analyzing customer sentiment from reviews or social media posts, allowing companies to adapt their strategies. Overall, NLP improves user experience, data analysis, and communication within software applications.
