Today, the basic managerial task is to strategize scientific work within the Federal Law № 172-FZ “On strategic planning in the Russian Federation”, including research mapping and schematization, connectivity analysis, resource maneuvering. “Digital Revolution” has created a tool of working with information arrays — BigData, which made it possible to structure scientific research, separating “human” and “inhuman” components. If scientific problem can be solved transferring BigData into DeepData, we should attribute it to scientific surveys (science study). Artificial intelligence today is already solving this type of problems better than a human being. As scientific research (science research) we shall consider creation of something new that has no obvious predecessors. Modern A.I. cannot carry out such work, as it goes beyond the Turing test. It is prerogative of a man, capable to distinguish another from new and important from unimportant. Separately we consider scientific investigation (science investigation): OverSite, search for alternative ways of scientific thinking development and the problem of changing scientific paradigm, post-Baconian cognition. Ranking of science through separating the levels of study, research and investigation is the basis for scientific research scaling, which is an integral part of the mechanism for scientific research strategic management.
