NLG converts structured data or semantic intents into human-readable text, while NLU converts text into formal representations (e.g., first-order logic); they are inverse operations in the NLP pipeline.
Summary
Text generation and text understanding are two sides of the same coin: one turns a formal meaning into a sentence, the other turns a sentence back into a formal meaning. This matters because it gives the system a round-trip check — if you build a text from a meaning and then parse it back, you should get the same meaning, which is a powerful way to catch errors and keep the system internally consistent.
