SenseNetworks - ETech 09

Mobile Phones Reveal the Behavior of Places and People

Our mission at SenseNetworks is to index the real world using location data. By harnessing this rich, natural and anonymized data, unprecedented possibilities emerge for user modeling, marketing, advertising, recommendation, search and collaborative filtering. Using machine learning algorithms, we can infer the context of a place and the tribe of a user from just their location data. It turns out that the flow and movement of people through the city (who is where and at what time) defines places and their character. Similarly, a person’s movement trail through the city reveals their personality and tribe. With location data, we build a network of places (how similar is place A to place B) and a network of people (how similar is person X to person Y). These networks let us cluster places and people as well as compute next-generation demographics and analytics. As your cell phone learns about you, it helps you find people, places and things you are interested in and your phone’s mapping software becomes your personal social navigator.
