Natural language processing (NLP) is a way for computers to understand and interpret human language. It has been around since the 1950s, when computers were first being used. NLP uses algorithms to break language down into smaller parts so that the computer can understand it. It also uses logic to interpret what is said and determine an appropriate response. NLP can be used for tasks such as automated customer service, automatic text translation, and speech recognition. It can even be used to help improve search engine results. NLP is an important part of modern technology because it helps computers to understand and respond to people more accurately.
