Cognitive Personalization in Microtask Design

Abstract

Today digital labor increasingly advocates for the inclusion of people who are excluded from society in some way. The proliferation of crowdsourcing as a new form of digital labor consisting mainly of microtasks that are characterized by a low level of complexity and short time periods in terms of accomplishment has allowed a wide spectrum of people to access the digital job market. However, there is a long-recognized mismatch between the expectations of employers and the capabilities of workers in microwork crowdsourcing marketplaces. Cognitive personalization has the potential to tailor microtasks to crowd workers, thus ensuring increased accessibility by providing the necessary coverage for individuals with disabilities and special needs. In this paper an architecture for a crowdsourcing system intended to support cognitive personalization in the design of microtasks is introduced. The architecture includes an ontology built for the representation of knowledge on the basis of the concepts of microtasks, cognitive abilities, and types of adaptation in order to personalize the interface to the crowd worker. The envisioned system contains a backend and a frontend that serve as an intermediary layer between the crowdsourcing platform and the workers. Finally, some results obtained to evaluate the proposed system are presented.
