摘要
在众包竞赛中,众包方可以选择在竞赛过程中对于参赛者的表现给予反馈或者不给予反馈,还可以选择在竞赛开始前声明或者隐瞒自己的反馈策略。通过研究发现,反馈策略的优劣与众包方的收益类型相关,当众包方的收益等于所有参赛者的努力总和时,无反馈策略和事先声明的有反馈策略效果相同,而事先隐瞒的有反馈策略最优;当众包方的收益等于参赛者的最大努力水平时,无反馈策略最劣,而事先声明和事先隐瞒的有反馈策略都有可能占优,最优策略由参赛者人数、参赛者能力分布及收到反馈的人数所决定。
In a crowdsourcing contest,a crowdsourcer can choose to give some feedback or no feedback to contestants,and choose to announce or hide his/her feedback strategy.We find that the effect of the feedback strategy depends on the payoff type of the crowdsourcer.If the payoff is equal to the total efforts of all the contestants,hiding feedback strategy is optimal.If the payoff is equal to the highest effort of all the contestants,no feedback strategy is the worst,and the optimal strategy depends on the number and capability distribution of all the contestants and the number of the contestants who receive the feedback.
