A significant raw material of the 21st century — •Claudia Draxl — Physics Department and IRIS Adlershof, Humboldt-Universität zu Berlin — Fritz Haber Institute of the Max Planck Society, Berlin
The growth of data from simulations and experiments is expanding beyond a level that is addressable by established scientific methods. The so-called “4 V challenge” of Big Data – Volume (the amount of data), Variety (the heterogeneity of form and meaning of data), Velocity (the rate at which data may change or new data arrive), and Veracity (uncertainty of quality) – is clearly becoming eminent also in materials science. An issue, for example, is understanding errors in both experiment and theory; related to this, assigning error bars and trust levels to high-throughput screening results, as obtained by density-functional theory. Controlling our data, however, sets the stage for explorations and discoveries. Novel data-mining technology can find patterns and correlations in data that can’t be seen by a human eye. In fact, data-driven materials research is adding a new research paradigm to our scientific landscape.
