Natural language
자연어
The speech and writing people use every day. The name sets it apart from programming languages made for computers.
Overview
Natural language is the language people have come to use naturally as they live, such as English or Spanish. Computers originally understood only commands with fixed grammar. Human speech, where the same meaning can be said many ways, shortened or said indirectly, was very hard for computers.
The technology that lets computers understand and use natural language is called natural language processing (NLP). LLMs made this much easier. "Tell the AI in natural language" means asking in your everyday way of speaking, instead of using code or fixed commands.
An everyday example
Search used to mean typing only words like "Paris weather." Now you can ask the way you would speak, "do I need to bring an umbrella if I go to Paris tomorrow?" That change is thanks to computers learning to understand natural language.
Why it matters
You can now build programs, make tables and run devices by speaking, without knowing how to code. When a new AI feature says "in natural language," read it as "you can just say it."
