Abstract:

        Crowdsourcing provides an open, voluntary, and reliable environment for crowdsourcers and individuals to cooperate in achieving a cumulative result. In a crowdsourcing system, a proper incentive mechanism is essential for crowdsourcers to solicit high-quality work and sizeable participation of crowd workers. In this talk, we will introduce the state-of-art incentive mechanism design for crowdsourcing systems. We observe that with mobile social networking,a user enjoys an intrinsic benefit, which can be leveraged to complement extrinsic rewards provided by crowdsourcers. Referred to as network effects, such an intrinsic benefit becomes more significant as more users join and contribute to the crowdsourcing system.  We propose to incorporate network effects as a contributing factor to intrinsic rewards, and study its influence on the design of extrinsic rewards. We show that with our new incentive mechanism design, a crowdsourcer is able to attract more participants with higher contributed efforts; and the participants gain higher utilities from both intrinsic and extrinsic rewards.
