Bandit-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 کاملEfficient task assignment for spatial crowdsourcing: A combinatorial fractional optimization approach with semi-bandit learning
Spatial crowdsourcing has emerged as a new paradigm for solving problems in the physical world with the help of human workers. A major challenge in spatial crowdsourcing is to assign reliable workers to nearby tasks. The goal of such task assignment process is to maximize the task completion in the face of uncertainty. This process is further complicated when tasks arrivals are dynamic and work...
متن کاملOptimizing 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 کاملTask Routing and Assignment in Crowdsourcing based on Cognitive Abilities
Appropriate task routing and assignment is an important, but often overlooked, element in crowdsourcing research and practice. In this paper, we explore and evaluate a mechanism that can enable matching crowdsourcing tasks to suitable crowd-workers based on their cognitive abilities. We measure participants’ visual and fluency cognitive abilities with the well-established Kit of FactorReference...
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...
