How will a capable AI be likely to analyse and understand a human verbal expression?

How will a capable AI be likely to analyse and understand a human verbal expression?

Today, there are a number of different ways to accomplish this….

1. Chatbots typically use “pattern matching”.
2. Statistical (probabilistic) NLP (natural language processing) is something like a more sophisticated version of pattern matching in that it leverages N-grams, such as Bi-grams and Tri-grams, and/or Skip-grams (which are N-grams with spaces).
3. In the field of Machine Translation, there is something called an Interlingua, where concepts are encoded in non-verbal representations, making the transition from one to another, or many, languages easier, especially since the wording does not have to be verbatim.
