Exploring Real-time Urban Analysis
CityBeat is a social media tool that extracts real-time information about city life. Our system collects streams of geo-tagged photos and texts, identifies trends and offers an interactive visualization of urban activities. The result enables us to follow city rhythms and happenings by visualizing real-life experiences of people as they are shared online.
Studying City Life from Social Media Data
Our method uses publicly available hyper-local social media geo-tagged data in order to detect exceptional and ongoing activities in urban environments. Focusing on small urban regions (e.g. a street corner or a certain venue), we model time series of geo-tagged social media photos and texts to find abnormal signals that may reflect special events.
