Guoliang Li, Jiannan Wang, Yudian Zheng, Michael J. Franklin
2016 IEEE Transactions on Knowledge and Data Engineering  
We identify three important problems in crowdsourced data management. (1) Quality Control: Workers may return noisy or incorrect results so effective techniques are required to achieve high quality; (2  ...  ., the crowd) to apply human computation for such tasks. Thus, crowdsourced data management has become an area of increasing interest in research and industry.  ...  Quality Control The requester can select the quality-control techniques provided by the crowdsourcing platform, or design her/his own quality-control methods.  ...

Crowdsourcing for Social Multimedia at MediaEval 2013: Challenges, Data set, and Evaluation

Babak Loni, Martha A. Larson, Alessandro Bozzon, Luke Gottlieb
2013 MediaEval Benchmarking Initiative for Multimedia Evaluation  
This paper provides an overview of the Crowdsourcing for Multimedia Task at MediaEval 2013 multimedia benchmarking initiative.  ...  The 'basic human labels' were collected such that their noise levels would be characteristic of data gathered from crowdsourcing workers without using highly sophisticated quality control.  ...  The use of only a basic mechanism made it possible for participants of the task to explore more advanced quality control mechanisms in their approaches to the task.  ...

Sequence Effects in Crowdsourced Annotations

Nitika Mathur, Timothy Baldwin, Trevor Cohn
2017 Proceedings of the 2017 Conference on Empirical Methods in Natural Language Processing  
During rating tasks, seeing a low quality item may affect the score given to the next item either positively or negatively.  ...  In this paper, we explore sequence effects where annotations of an item are affected by the preceding items.  ...  Acknowledgments We thank the anonymous reviewers for their valuable feedback. This work was supported in part by the Australian Research Council.  ...
