Google DeepMind has poured cold water on rumours its AlphaGo Artificial Intelligence Go-playing program will face off against Chinese Go champion Ke Jie.

Deepmind co-founder Demis Hassabis rubbished the claims on Twitter.

"Contrary to internet rumours, we've not decided yet what to do next with #AlphaGo, once we have, there will be an official announcement here," Hassabis tweeted on Monday.

Currently, Ke is ranked first in the world.

The news was originally released by Yang Junan, secretary general of the International Go Federation, at a news conference for the 37th World Amateur Go Championship, on June 4.

Yang said representatives had been in contact with the team behind AlphaGo and would set up a match by the end of this year.

AlphaGo defeated South Korean Go grandmaster Lee Sedol 4-1 at the Google DeepMind Challenge Match held in March, sparking global interest in AI.
