What do you do with the world's most advanced supercomputer? Give it a job in a call centre, of course...

Technology company IBM is putting its supercomputer Watson to work - in a robot call centre. The artificially intelligent computer system is taking on the role of customer service manager and will be called Watson Engagement Advisor. Companies will be able to sign up to IBM's service and its customers can then ring a helpline and complain or get help from the Question Answering (QA) machine. The IBM Watson Mobile Developer Challenge invited teams to design mobile apps using Watson's, pictured, cognitive computing capabilities. The 25 finalists will now submit prototypes for judging, after which only five teams will present proposals to IBM.
