Right. The trouble with that approach is that it's great on the easy cases and degrades rapidly with scale.

This sounds like is a fix for a very specific problem. An airline chatbot told a customer that some ticket was exchangeable. The airline claimed it wasn't. The case went to court. The court ruled that the chatbot was acting as an agent of the airline, and so ordinary rules of principal-agent law applied. The airline was stuck with the consequence of their chatbot's decision.[1]

Now, if you could reduce the Internal Revenue Code to rules in this way, you'd have something.

Yes, as I said in another comment: "By constraining the field it is trying to solve it makes grounding the natural language question in a knowledge graph tractable."

IRS rules should be tractable!
