For a long time the development of big data technologies was
inspired by business intelligence [3] and by big science (such
as the Large Hadron Collider at CERN) [4]. But when in 2009
Google Flu, simply by analyzing Google queries, predicted flulike
illness rates as accurately as the CDC’s enormously complex
and expensive monitoring network [5], some analysts started to
claim that all problems of modern healthcare could be solved
by big data [6].
