MIT researcher Deb Roy wanted to understand how his infant son learned language — so he wired up his house with videocameras to catch every moment (with exceptions) of his son’s life, then parsed 90,000 hours of home video to watch "gaaaa" slowly turn into "water." Astonishing, data-rich research with deep implications for how we learn.
What’s even more amazing is the way the reserachers have applied their data mining techniques to the relationship between media events and social media reactions to track the way America’s thinking in real time.
This is a must watch for people interested in massive passive data collection and interpretation. And anyone who uses social media.
