Big data represents a paradigm shift on how we view and interpret observations in the world around us. Lots of small sensors come together to provide hugely complex data streams, that are gathered with modern technology capable of finding semantic structure and hence transforming the data into human-readable information. Steven Adler of IBM mentioned examples of predicting and preventing traffic congestion using smartphones’ GPS-transmitters. The value of big data analysis stretches over many societal problems, but can also help analyse occurrences in nature, such as potential natural disasters.
