Man-machine collaboration at heart of new Artificial Intelligence XPrize

Registration has just opened up for an all new US 5 million XPrize, this time focusing on getting humans collaborating better with artificial intelligence to solve major global issues. Unlike previous competitions, this XPrize, sponsored by IBM's Watson division, doesn't feature a set of pre-determined goals, but instead challenges teams to come up with their own. You might be familiar with XPrize from its ongoing Google Lunar effort, which is seeing small teams from around the world compete to successfully land a robot on the Moon. It's a seriously ambitious project, and one that has seen rivals team up in the hope of winning out against the competition. This new project is totally different to the Lunar XPrize, but it's no less ambitious.
