  • A Survey of the Use of Crowdsourcing in Software Engineering
    A Survey of the Use of Crowdsourcing in Software Engineering Ke Mao⇤, Licia Capra, Mark Harman, Yue Jia Department of Computer Science, University College London, Malet Place, London, WC1E 6BT, UK Abstract The term ‘crowdsourcing’ was initially introduced in 2006 to describe an emerging distributed problem-solving model by online workers. Since then it has been widely studied and practiced to support software engineering. In this paper we provide a compre- hensive survey of the use of crowdsourcing in software engineering, seeking to cover all literature on this topic. We first review the definitions of crowdsourcing and derive our definition of Crowdsourcing Software Engineering together with its taxonomy. Then we summarise industrial crowdsourcing practice in software engineering and corresponding case studies. We further analyse the software engineering domains, tasks and applications for crowdsourcing and the platforms and stakeholders involved in realising Crowdsourced Software Engineering solutions. We conclude by exposing trends, open issues and opportunities for future research on Crowdsourced Software Engineering. Keywords: Crowdsourced software engineering, software crowdsourcing, crowdsourcing, literature survey 1. Introduction crowdsourcing in software engineering, yet many authors claim that there is ‘little work’ on crowdsourcing for/in software en- Crowdsourcing is an emerging distributed problem-solving gineering (Schiller and Ernst, 2012; Schiller, 2014; Zogaj et al., model based on the combination of human and machine compu- 2014). These authors can easily be forgiven for this miscon- 30 tation. The term ‘crowdsourcing’ was jointly1 coined by Howe ception, since the field is growing quickly and touches many 5 and Robinson in 2006 (Howe, 2006b). According to the widely disparate aspects of software engineering, forming a literature accepted definition presented in the article, crowdsourcing is that spreads over many di↵erent software engineering applica- the act of an organisation outsourcing their work to an unde- tion areas.
