Design And Implementation Of A Workflow System For Crowdsourcing

The micro-task crowdsourcing platform has become a new technical trend that can convene a large number of people to address the tasks presented by online requesters.But the current popular common package platform(like Mechanical Turk)on the task are simple and independent.With the popularity of crowdsourcing applications and the need for users to solve complex tasks using crowdsourcing platforms,new models of crowdsourcing and workflows have emerged.Implementing complex work with the crowdsourcing platform requires focusing on workflow design,breaking up operations into multiple tasks and working with multiple workers.How do you implement complex workflow design and task management?This article describes a new system that recruits crowdsourcing workers to help requesters plan and solve complex work.With the support of this system,the visualization and implementation of the crowdsourcing process are achieved.During the execution of the workflow,the system can manage the dependencies between tasks;the requester can view the status of the workflow in real time,intervene in changing tasks and solutions.After the workflow is finished,the requester can also re-use the workflow to modify the workflow.Using this system,users can develop a variety of crowdsourcing applications that do not require programming and have higher speed and quality.These features reduce the barriers to public demand for complex work.Preliminary experiments show that the system can successfully create workflows to solve difficult tasks from the most common point of view.
