Listening to and Visualising the Pulse of Our Cities Using Social Media and Call Data Records
Emanuele Della Valle, Marco Balduini · Lecture notes in business information processing · 2015
Methods and technologies exist to capture a sharp digital reflection of a city and to track its evolution with a decreasing delay, but decision makers will not benefit from our ability to feel the pulse of a city unless we provide them with tools to visually perceive emerging patterns and observe their dynamics. This keynote reports on a two year long experience in feeling the pulse of Milan with CitySensing. This system–developed by Politecnico di Milano and Telecom Italia–allows fusing and visually making sense of social media streams and privacy-preserving aggregates of Call Data Records. The effectiveness of CitySensing was demonstrated during Milan Design Week 2013 and 2014 by realising a visual analytics dashboard for event managers and a public storytelling installation.
