报告题目：Human Mobility Modeling on CrowdSensed Data: Insights and Challenges
报告摘要：The ubiquitous availability of location sensing devices in the form of smartphones, cars, taxis, and other devices combined with the ability to collect data at scale using crowdsensing platforms enables the fine grained monitoring and modeling of human movement, both at the individual level and a group level. In this talk, we will first examine human movement data from call-detail records and taxi cabs and provide insights into "routes" and "timing" aspects of the movement patterns in large cities. We will then pose the question of efficiently analyzing large volumes of mobility data at scale (both real-time and non-real-time aspects) and have an open discussion regarding these challenges.
