：数字人文类众包抄录项目对文化遗产的转录、存储、传播和发展而言具有重要意义。由于该类型的项目具有专业性高、任务量大等特点，因此保证抄录质量、提高任务绩效是优化众包抄录的主要任务之一。本文以国内具有代表性的数字人文类众包抄录平台--盛宣怀档案众包抄录项目为例，选择了准实验的研究方法，探讨不同任务复杂度和领域知识水平下，众包抄录任务的绩效差异。研究结果表明，任务复杂度和领域知识水平及两者之间的交互作用均影响数字人文类众包抄录平台中的任务绩效。研究结论为国内数字人文类众包平台的建设提供了任务设计、参与者招募及任务匹配等方面的实践建议。

Crowdsourcing transcription projects in digital humanity domain are of great significance to the transcription, storage, disseminate and development of cultural heritage. However, because of the heavy workload and the high-level professionalism in the crowdsourcing projects, it becomes necessary to ensure the performance of crowdsourcing tasks. This paper adopts Transcribe-Sheng Project, one of the typical crowdsourcing projects in digital humanity domain in China, as a case. We conduct a quasi-experiment to explore the difference of task performance in the crowdsourcing transcription projects from two perspectives-task complexity and domain knowledge. Our findings reveal that both task complexity and domain knowledge significantly influence task performance. What's more, there is an interaction effect exists between task complexity and domain knowledge on task performance. Based on these findings, we provide some practical suggestions on task design, participants' recruitment and task fit for the crowdsourcing transcription projects in digital humanity domain in China.
