长期参与众包的两阶段拍卖机制

Two-Stage Auction Mechanism for Long-Term Participation in Crowdsourcing

Timothy Shin Heng Mak, Albert Y. S. Lam

摘要:

众包已经成为各种人工智能应用收集数据的重要工具,拍卖可以成为众包平台中分配工作和确定报酬的有效方式。在本文中,我们专注于小任务的众包,如图像标签和语音记录,我们面临着许多挑战。首先,工人对他们愿意做的工作量有不同的限制,他们也可能在争取工作时误报这些限制。其次,如果拍卖随着时间的推移而重复,不成功的工人可能会退出系统,减少竞争和多样性。为了解决这些问题,我们首先扩展了著名的迈尔森的最优拍卖机制的单参数投标的情况下,投标的单位成本的工作,最大的工作量之一是愿意做的,和实际完成的工作的结果。我们表明,一个简单的支付机制是足以确保从工人的主导战略,这种主导战略是强大的真正的效用函数的工人。其次,我们提出了一种新的,灵活的工作分配机制,它允许请求者之间的成本效率和平等的平衡。虽然最大限度地降低成本显然很重要,但鼓励平等分配工作可以增加劳动力的多样性,并促进对众包平台的长期参与。我们的主要结果证明了分析和验证,通过模拟。

英文摘要:

Crowdsourcing has become an important tool to collect data for various artificial intelligence applications and auction can be an effective way to allocate work and determine reward in a crowdsourcing platform. In this paper, we focus on the crowdsourcing of small tasks such as image labelling and voice recording where we face a number of challenges. First, workers have different limits on the amount of work they would be willing to do, and they may also misreport these limits in their bid for work. Secondly, if the auction is repeated over time, unsuccessful workers may drop out of the system, reducing competition and diversity. To tackle these issues, we first extend the results of the celebrated Myerson's optimal auction mechanism for a single-parameter bid to the case where the bid consists of the unit cost of work, the maximum amount of work one is willing to do, and the actual work completed. We show that a simple payment mechanism is sufficient to ensure a dominant strategy from the workers, and that this dominant strategy is robust to the true utility function of the workers. Secondly, we propose a novel, flexible work allocation mechanism, which allows the requester to balance between cost efficiency and equality. While cost minimization is obviously important, encouraging equality in the allocation of work increases the diversity of the workforce as well as promotes long-term participation on the crowdsourcing platform. Our main results are proved analytically and validated through simulations.
