From the Announcement:

A study from Thomson Reuters released today predicts that, based on substantial and recent growth, India’s research productivity will be on par with most G8 nations within 7-8 years and could overtake them between 2015-2020.

The study, Global Research Report: India, informs policymakers about the research and collaboration potential of India and its current place in world science. The study is part of a new series of Global Research Reports from Thomson Reuters that will illustrate the changing landscape and dynamics of the global research base around the world.
