Summary and Download

This paper is a new framework to discovery short and long-term patterns over geo-spatiotemporal data (e.g. traffic, weather, etc.). Short-term patterns show propagation of geo-spatiotemporal entities which cause other entities to happen (e.g. rain –> accident –> traffic jam). Long-term patterns show the influence of a temporally long-term entity on its spatiotemporal neighborhood (e.g. major construction –> more traffic issue).
