报告简介:

In many situations, the wisdom of the crowds is superior to that of a few experts. With the increasing popularity of mobile devices interconnected via wireless networks, crowdsourcing has emerged as is a new computing paradigm, which uses collective intelligence to accomplish computing tasks. In this computing paradigm, individual users can make a profit by providing service to needed clients. Crowdsourcing finds its applications in WiFi mapping, traffic monitoring, mobile phone sensing, and is the winning strategy in the DARPA network challenge. Examples of crowdsourcing include Wikipedia, Open Innovation, the Linux open source project, and WAZE—a community based traffic and navigation app.

However, crowdsourcing has its limitations and challenges. How to mobilize users to contribute to the system? How to eliminate/reduce conflicts among users of the system? How to deal with noise in the crowdsourced data? The list goes on and on. In this talk, we will discuss recent research advances and future research opportunities related to crowdsourcing computing paradigm, truthful incentive mechanisms, the problems of and solutions for free-riding and false reporting, as well as nose in data obtained from crowdsourcing.
