Urbanity: A System for Interactive Exploration of Urban Dynamics from Streaming Human Sensing DataEI

摘要

With the urbanization process worldwide, modeling the dynamics of peopleu0027s activities in urban environments has become a crucial socioeconomic task. We present Urbanity, a novel system that leverages geo-tagged social media streams for modeling urban dynamics. Urbanity automatically discovers the spatial and temporal hotspots where peopleu0027s activities concentrate; and captures the cross-modal correlations among location, time, and text by jointly mapping different units into the same latent space. With Urbanity, the end users ...更多
