Ai chatbot of the future

Ai chatbot should be able to learn the words to pick in a sentence to give the appropriate answer.Instead of programming those answers in.It would make them a whole lot better.Does anybody have any suggestion on how this would be possible?Maybe you could program the ai chatbot to ingnor words of a certain size and pay antention to words of larger size.That is just a start i think.

To make a ai chatbot even better.It could make up words and then ask questions about them.Some of the chatbots are able to learn.So that would not be difficult.Program the chatbot to know what is a word.And when it comes up with a actual word.It will ask what does that mean.Then it will learn.
