摘要: 提出一种基于投票一致性的工作者严谨度动态评估策略,将众包任务集合划分为多个任务子集,每个任务子集看作一个工作阶段.在任意工作阶段结束后,通过记录工作者投票的数量,以及工作者与工作组投票值一致的投票数量,对工作者的严谨度进行评估,从而检测出不合格的工作者.然后对不合格的工作者进行动态替换,从而保证工作组的正确率满足任务的精度阈值.通过对三种真实数据集进行实验测试,证明本文提出的工作者质量动态评估方法和替换策略具有较好的效果.

Abstract: A dynamic evaluation strategy for the worker precision based on the voting consistency is proposed. The crowdsourcing task set is divided into multiple task subsets and each of them is regarded as a task phase. When a task phase is finished, the whole votes and the number of the worker’s voting value agreeing with the working group’s one are recorded. Then, the workers’precision is evaluated and the unqualified workers are detected. All the unqualified workers are dynamically replaced to ensure that the correct rate of the group exceeds the task accuracy threshold. The effectiveness of the proposed method is evaluated using three realworld datasets, which shows that the method can achieve good performance.

Key words: crowdsourcing, voting, consistency, quality evaluation, dynamical replacement
