Optimizing Task Assignment for Crowdsourcing Environments
In a crowdsourcing system, Human Intelligence Tasks (HIT-s) (e.g., sentence translation, photo matching, providingkeywords for videos) can be conveniently specified. TheseHITs are available to a large pool of workers, who are paidupon completing their selected HITs. Since these workersmay have different capabilities, some difficult HITs may notbe satisfactorily performed...
متن کاملBandit-Based Task Assignment for Heterogeneous Crowdsourcing
We consider a task assignment problem in crowdsourcing, which is aimed at collecting as many reliable labels as possible within a limited budget. A challenge in this scenario is how to cope with the diversity of tasks and the task-dependent reliability of workers; for example, a worker may be good at recognizing the names of sports teams but not be familiar with cosmetics brands. We refer to th...
متن کاملTask Assignment on Spatial Crowdsourcing (Technical Report)
Recently, with the rapid development of mobile devices and the crowdsourcing platforms, the spatial crowdsourcing has attracted much attention from the database community. Specifically, spatial crowdsourcing refers to sending a location-based request to workers according to their positions, and workers need to physically move to specified locations to conduct tasks. Many works have studied task...
متن کاملMotivation-Aware Task Assignment in Crowdsourcing
We investigate how to leverage the notion of motivation in assigning tasks to workers and improving the performance of a crowdsourcing system. In particular, we propose to model motivation as the balance between task diversity–i.e., the difference in skills among the tasks to complete, and task payment–i.e., the difference between how much a chosen task offers to pay and how much other availabl...
متن کاملOnline Task Assignment in Crowdsourcing Markets
We explore the problem of assigning heterogeneous tasks to workers with different, unknown skill sets in crowdsourcing markets such as Amazon Mechanical Turk. We first formalize the online task assignment problem, in which a requester has a fixed set of tasks and a budget that specifies how many times he would like each task completed. Workers arrive one at a time (with the same worker potentia...
