Contributor(s): Dr Kavita Abraham, Dr Jon Adams, Dr Robert Hudson | Don't judge a book by its cover? Don't be ridiculous. We constantly make judgements on books - from where it appears in a shop, its pretty cover, its heft or subject matter, the praise and criticism we hear about it. Reviewers are even more prejudiced. They know the author, or hate the publisher or, even worse, are a meticulous and lucid expert on the subject. All human readings are subjective. Is there another way? Would an objective reading - some preconceptionless robotic analysis, for instance - be preferable? Is it even possible? And what questions might a robot help us answer?
