Management of big semantic data

In 2007 Jim Gray preached about the effects of the Data Deluge in the sciences (Hey, Tansley, and Tolle 2009). Whereas experimental and theoretical paradigms originally led science, some natural phenomena were not easily addressed by analytical models. In this scenario, computational simulation arose as a new paradigm enabling scientists to deal with these complex phenomena. Simulation produced increasing amounts of data, particularly from the use of advanced exploration instruments (large-scale telescopes, particle colliders, etc.) In this scenario, scientists were no longer interacting directly with the phenomena, but used powerful computational configurations to analyze the data gathered from simulations or captured by instruments. Sky maps built from the Sloan Digital Sky Survey observations, or the evidences found about the Higgs Boson are just two successful stories of just another paradigm, what Gray called the fourth paradigm: the eScience.
