Big Data: water wordscape
MIT cognitive scientist Deb Roy exemplifies the power of Big Data in his latest TED Talk: harvesting big insights from "the largest home video collection ever made" to understand the process of how a child learns language.
In this example, Deb Roy's team captures every time his son ever heard the word water along with the the context he saw it in. They then used this data to penetrate through the video, find every activity trace that co-occurred with an instance of water and map it on a blueprint of the apartment. That's how they came up with wordscapes: the landscape that data leaves in its wake.
