The birth of a word


90,000 hours of video recording, 7 millions of words recorded and, as a result, a model based on big data analysis that explains how a baby learns to talk. 
This is the fascinating experiment that Deb Roy, a MIT researcher who studied how his first son began speaking, tells us about in his talk at TED
But he went even further: together with his collegues, he has applied this pattern to study the development of conversations on social media about a TV programme. Discovering that “it's like building a microscope or telescope and revealing new structures about our own behavior around communication”.
