报告摘要:
Crowdsourcingis a new computing paradigm where humans are enrolled actively to participateinto the procedure of computing, especially for the tasks that areintrinsically easier for human than for computers. Not surprisingly, with thedevelopment of mobile Internet, the magic power of crowdsourcing is nowexpanding to physical world, where each user is treated as a mobile computingunit that can be activated and guided for certain tasks. Such practice is ingeneral termed as spatial crowdsourcing, featuring task dispatching and dynamicpricing as its core technical niches. Therefore, it serves as the fundamentalprototype of a cluster of industrial applications like Citizen Sensing(Waze),P2P ride-sharing(Uber), Real-time O2O service(Instacart, Postmates) and so on.
In this talk, I will first demonstrate our spatial crowdsourcing system,G-mission, Then, I will introduce the theoretical and practical development ourspatial crowdsourcing project. Finally, I will talk about some interestingfuture works on G-mission.

Lei Chen received the BS degree in computer science and engineering from Tianjin University, Tianjin, China, in 1994, the MA degree from Asian Institute of Technology, Bangkok, Thailand, in 1997, and the PhD degree in computer science from the University of Waterloo, Canada, in 2005.
He is currently an associate professor in the Department of Computer Science and Engineering, Hong Kong University of Science and Technology. His research interests include crowdsourcing, social network analysis, probabilistic and uncertain databases, and privacy-preserved data publishing. The system developed by his team won the excellent demonstration award in VLDB 2014. In 2015, he got the SIGMOD Test-of-Time Award. Currently, he serves as Editor-in-Chief of VLDB Journal and associate Editor-in-Chief for IEEE Transaction on Data and Knowledge Engineering. He was PC Track chairs for SIGMOD 2014, VLDB 2014, ICDE 2012, CIKM 2012, SIGMM 2011. He is a member of the VLDB endowment committee and the chairman of ACM SIGMOD China Chapter.
