Crowdsourcing

Crowdsourcing: participatory digital research methods

What is crowdsourcing?

Researchers in wide range of academic disciplines have begun to experiment with ‘crowdsourcing’ - creating or mobilising online communities of volunteers to assist them in their research. As Dunn remarks (2013) ‘crowdsourcing’ when applied in an academic context generally differs significantly to the meaning of the term in a business context where it was originally coined to describe a process of ‘outsourcing’ to ‘the crowd’, functions which were previously performed by employees (Howe: 2006). By contrast, academic crowdsourcing projects may have more in common with other kinds of participatory research initiatives. ‘Citizen science’, for example, which is described in a recent report by the UK Environmental Observation Framework, as “the involvement of volunteers in science”, is sometimes used interchangeably with ‘crowdsourcing’ as a label to describe research projects which involve an online, open call for participation by the public (see EOF 2012, for example).

The scale of public participation in academic research projects using crowdsourcing methods is impressively large. The Zooniverse projects have more than 800,000 registered users, (www.zooniverse.org), while the pioneering game Foldit, where participants play with digital models of proteins, has more than 300,000. Trove, which crowdsources annotations and corrections to scanned newspaper text in the collections of the National Library of Australia, has around 75,000 users who have produced nearly 100 million lines of corrected text since 2008. A notable feature of many of these projects is that the bulk of the work by ‘the crowd’ is actually done by a small core of highly committed volunteers (see Hagon, 2013 for a discussion of this phenomenon in Trove).

The tasks which volunteers perform in academic crowdsourcing projects vary widely across disciplines, but a common feature of many projects is that they mobilise large numbers of people to undertake tasks which computers cannot yet do effectively (such as pattern recognition or reading handwriting) on a scale which research institutions will not fund by employing professionals to carry out the same task. Paul Hagon estimates that the volunteers who corrected scanned text in Trove carried out work to the value of 12m Australian dollars. Other crowdsourcing projects may invite volunteers to share their localised or specialised knowledge with researchers or cultural heritage institutions, for example by enriching catalogue descriptions of museum and gallery holdings.

Thus, the combination of methods used by academic crowdsourcing projects requires building research teams which cross traditional disciplinary boundaries. Crowdsourcing methods are also a form of public engagement as their use depends on the mobilisation of volunteers who are either not academic researchers or not employed by the project concerned.

Major funders are beginning to support research projects using crowdsourcing methods, and the Arts and Humanities Research Council (AHRC) last year funded research into a scoping study on the use of crowdsourcing methods in the Humanities (Dunn and Hedges, 2012).

We are a network of researchers at the University of Cambridge who are interested in how the use of digital tools is transforming scholarship in the humanities and social sciences. This transformation spans both the content and practice of humanities research, as the diffusion of digital technologies opens up new fields of study and generates research questions which breach traditional disciplinary boundaries.
