CitySensing: Fusing City Data for Visual Storytelling

The authors´ CitySensing system captures at places social media streams and anonymous Call Data Records (CDR) during city-scale events. It semantically annotates the social media streams before fusing it with privacy-preserving aggregates of CDR. The result is analysed and repurposed to feed a public installation where visual story telling assumes a leading role in allowing the audience to perceive emerging patterns and to observe their dynamics. The authors demonstrate the efficacy of the visualization on the real-world data of two editions of Milan Design Week. This article is part of a special issue on social multimedia and storytelling.
