Tennis-Wimbledon? It's elementary, dear Watson

London

DEEP in the bowels of the All England Club, an army of employees from one of the world's technology giants are teaching a computer named Watson to master tennis.

Seven-times Wimbledon champion Roger Federer can relax though. A silicon-chipped cyborg is not about to wreak havoc on his beloved Centre Court. Watson is a cognitive computer designed by IBM that played Gary Kasparov at chess and beat the most successful contestant on hit US game show Jeopardy in a US$1 million challenge.
