Sure - I guess what I was asking is how to make sure everything is okay in the unstructured -> structured conversion.

"My name is John and I'm 40 years old" -> {name:"John", age:40}

How can you gain confidence that the AI doesn't spit out {name:"John", age:41}

The only thing I do currently is have a massive test suite to gain some statistical confidence it works, but I worry about situations like a person having a rare unicode character in their name (not to even speak of people intentionally trying to trick the system)
