Network based mechanisms for competitive crowdsourcing
Sankar Kumar Mridha, Malay Bhattacharyya · 2018
The working principle of crowd in a crowdsourcing platform is either competitive or collaborative. Occasionally, the tasks submitted to crowdsourcing environments are decomposable. They are challenging to solve because decomposition and composition of tasks and proper selection of workers are difficult. We show that by appropriate inclusion of collaboration in a competitive crowdsourcing environment, we can handle decomposable-type tasks given with posted-price in a better way. We initially attempt to manage 2-decomposable tasks with appropriate mechanism design. Extending it further to n-decomposable tasks, we propose a network based mechanism to choose the best mixture of sub-tasks in a competitive environment for selecting the winners. We are currently interested in developing mechanisms to remove the participation bias from such environments.
