On Cost-Effective Incentive Mechanisms in Microtask Crowdsourcing

PROJECT TITLE :

On Cost-Effective Incentive Mechanisms in Microtask Crowdsourcing

ABSTRACT:

While microtask crowdsourcing provides a new way to resolve giant volumes of little tasks at a a lot of lower value compared with traditional inhouse solutions, it suffers from quality issues because of the shortage of incentives. On the other hand, providing incentives for microtask crowdsourcing is challenging since verifying the standard of submitted solutions is thus expensive that it can negate the advantage of microtask crowdsourcing. We tend to study value-effective incentive mechanisms for microtask crowdsourcing in this paper. In explicit, we tend to take into account a model with strategic workers, where the first objective of a employee is to maximize his own utility. Based mostly on this model, we initial analyze 2 basic mechanisms and show their limitations in collecting high-quality solutions with low cost. Then, we have a tendency to propose a cost-effective mechanism that employs quality-aware worker coaching as a tool to stimulate employees to supply high-quality solutions. We prove theoretically that the proposed mechanism can be designed to obtain high-quality solutions from workers and guarantee the budget constraint of the requester at the identical time. Beyond its theoretical guarantees, we tend to any demonstrate the effectiveness of our proposed mechanisms through a group of behavioral experiments.
