摘　　要：针对现有众包系统在质量控制方面存在的诸多问题,尤其是现有研究方法主要把精力集中在如何筛选精确的结果上而忽略了如何从任务分配上提高众包质量,提出了一种基于信誉度的众包任务分配方法。通过构建任务分配模型,基于时间窗口获得工作者的可信度证据序列求得可信度,利用信誉度将可用工作者和未分配的任务进行动态匹配,实验结果表明,利用此方法可以在合理的时间内高质量的完成众包任务。Because of many problems in the quality control of the existing crowdsourcing system,especially the existing research methods focus on how to filter the exact results and ignore how to improve the quality of crowdsourcing by the task allocation,so the new method is proposed that a based on the credibility of the crowdsourcing task allocation method.By constructing the task allocation model,the trust worthiness of the workers is obtained based on the time window,and the reliability of the available workers and the unallocated tasks is obtained by using the credibility.The experimental results is show that the method can be used to complete the task of mass package in the reasonable time.
