Re: Here's a little oil for the wheels and gears, cogs and high rollers
An AI finds a piece of text which most fully answers a question, in contexts and subtexts of both the question and the piece. Looking for the piece the AI establishes its cause-and-effect relationships, selecting one that best fits the question. And finally in the piece the AI finds the answer, as a phrase, sentence or paragraph, modifying it appropriately.
If the AI can't find the right piece of text,it tries to detect it wherever it can, which is called Machine Learning.
