面向工作者-任务专业化模型的众包标签

Crowdsourced Labeling for Worker-Task Specialization Model

KAIST(韩国科学技术院)

Doyeon Kim, Hye Won Chung

摘要:

我们认为众包标签下的$d$型工人任务专业化模型,其中每个工人和任务与一个特定的类型之间的有限类型集和工人提供了一个更可靠的答案,任务的匹配类型比任务的不匹配类型。我们设计了一个推理算法,恢复二进制任务标签(任何给定的恢复精度),通过使用工人聚类,工人技能估计和加权多数表决。所设计的推理算法不需要任何关于工作者/任务类型的信息,并且以最佳已知性能(每个任务的最小查询数)实现任何目标恢复精度。

英文摘要:

We consider crowdsourced labeling under a $d$-type worker-task specialization model, where each worker and task is associated with one particular type among a finite set of types and a worker provides a more reliable answer to tasks of the matched type than to tasks of unmatched types. We design an inference algorithm that recovers binary task labels (up to any given recovery accuracy) by using worker clustering, worker skill estimation and weighted majority voting. The designed inference algorithm does not require any information about worker/task types, and achieves any targeted recovery accuracy with the best known performance (minimum number of queries per task).
