We all know, on a gut level, what is real and what is fiction. For example, we know that Albert Einstein was a real person, but Hamlet was fictional.
What are there levels of fiction? For example, is Hamlet more real than a character that we only hear about in a play but who is never on stage?
Could we create a hierarchy of fictional realities, through some reasonably objective criteria? If so, what would those criteria be?
It reminds me of a paper of my friend – Mining Visualness. Now we have a title of a new paper: Mining Realities 🙂 A well-trained AI should be able to learn that by searching on Google Images.
