| Summary/Abstract |
BIG DATA ARE A SALIENT FEATURE of the information tsunami that characterized the end of the twentieth and the beginning of the twenty‐first century. As a result of the incessant rise in computational power, communication velocity, and storage capacity, new knowledge is accumulating at an exponential rate. Between 2006 and 2011, the amount of data in the world increased almost ninefold. Today, it is expected to double every two years.
