NLP, NLU, and NLG: What's The Difference? A Comprehensive Guide - KDnuggets

Have you ever used a smart assistant (think something like Siri or Alexa) to answer questions for you? The answer is more than likely "yes", which means that you are, on some level, already familiar with what's known as natural language processing (NLP). NLP is the combination of methods taken from different disciplines that smart assistants like Siri and Alexa use to make sense of the questions we ask them. It combines disciplines such as artificial intelligence and computer science to make it easier for human beings to talk with computers the way we would with another person. This idea of having a facsimile of a human conversation with a machine goes back to a groundbreaking paper written by Alan Turing -- a paper that formed the basis for NLP technology that we use today.
