Natural Language Processing
Natural Language Processing (NLP) is a technology that helps computers understand and work with human language. Think of it as teaching computers to read, understand, and respond to text and speech the way humans do. Companies use NLP for things like customer service chatbots, analyzing customer feedback, or sorting through large amounts of text documents. This technology is part of artificial intelligence and machine learning, similar to how tools like ChatGPT work. When you see this on a resume, it means the candidate has experience making computers understand and process human language in useful ways for businesses.
