Natural Language Processing (NLP) is a field in Artificial Intelligence, and is also related to linguistics. On a high level, the goal of NLP is to program computers to automatically understand human languages, and also to automatically write/speak in human languages. We say "Natural Language" to mean human language, and to indicate that we are not talking about computer (programming) languages.
