众包环境下的动态任务分配

Dynamic Task Allocation for Crowdsourcing Settings

Princeton University(普林斯顿大学)

Angela Zhou, Irineo Cabreros, Karan Singh

摘要:

我们考虑众包问题的最优预算分配问题,将用户分配到任务中,以最大限度地提高我们对众包答案的最终信心。这种优化的工人分配方法使我们能够提高任何流行的众包估计算法的效率。我们考虑一个互信息解释的众包问题,这导致一个随机子集选择问题的子模块目标函数。我们目前的实验模拟结果表明,我们的动态任务分配方法的有效性,以实现更高的准确性,可能需要更少的标签,以及改进以前的方法,这是敏感的用户的比例问题。

英文摘要:

We consider the problem of optimal budget allocation for crowdsourcing problems, allocating users to tasks to maximize our final confidence in the crowdsourced answers. Such an optimized worker assignment method allows us to boost the efficacy of any popular crowdsourcing estimation algorithm. We consider a mutual information interpretation of the crowdsourcing problem, which leads to a stochastic subset selection problem with a submodular objective function. We present experimental simulation results which demonstrate the effectiveness of our dynamic task allocation method for achieving higher accuracy, possibly requiring fewer labels, as well as improving upon a previous method which is sensitive to the proportion of users to questions.
