A Social Network Engaged Crowdsourcing Framework for Expert Tasks

Crowdsourcing is an online, distributed problem-solving and production model in which individuals post short micro-task that online workers can complete in exchange for a small payment. Yet, with the rapid development of crowdsourcing in different fields, many complex tasks which request workers with domain-specific skills or knowledge challenge the current crowdsourcing platforms. In this paper, we focus on the issue of producing expert-level crowdsourcing with non-expert contribution. We firstly did a survey to get a comprehensive view of the mainly research related to this issue. We summarize and categorize the existing approaches, and identify the main challenges that raise from the current approaches. After that, we propose a social network engaged crowdsourcing framework and conduct the preliminary study to explore its ability in performing the tasks with the need of domain-specific skills and knowledge.
