A text or speech system uses Natural Language Generation (NLG) to process user input and return an answer that better matches the task and language.
Why it matters
Natural Language Generation (NLG) matters because task of generating readable language from data, prompts or structured inputs can change how teams build, evaluate or choose AI systems.
How it works
The system represents text, analyzes structure or meaning, and evaluates whether outputs match the task and context. For Natural Language Generation (NLG), the key is to connect the definition with input data, assumptions, measurable outcomes and deployment limits.
Where it is used
- Used in chatbots, search, summarization, extraction, translation and text analytics.
Limitations
