Gazouille: Detecting and Illustrating Local Events from Geolocalized Social Media Streams

We present Gazouille, a system for discovering local events in geo-localized social media streams. The system is based on three core modules: i social networks data acquisition on several urban areas, ii event detection through time series analysis, and iii a Web user interface to present events discovered in real-time in a city, associated to a gallery of social media that characterize the event.
