NLP, NLU, NLG and how Chatbots work – Chatbot's Life

Various acronyms and words are thrown around while talking about Chatbots and at first glance it seems they're all interchangeable with each other. To understand what the future of chatbots holds, let's familiarize ourselves with three basic acronyms. I. NLP, or Natural Language Processing is a blanket term used to describe a machine's ability to ingest what is said to it, break it down, comprehend its meaning, determine appropriate action, and respond back in language the user will understand. NLU, or Natural Language Understanding is a subset of NLP that deals with the much narrower, but equally important facet of how to best handle unstructured inputs and convert them into a structured form that a machine can understand and act upon. While humans are able to effortlessly handle mispronunciations, swapped words, contractions, colloquialisms, and other quirks, machines are less adept at handling unpredictable inputs.
