We are working on crowdsourcing techniques to support volunteer communities (rather than to get work done with paid workers). In these communities, it can be infeasible or undesirable to recruit external paid workers. For example, nonprofits may lack the funds to pay external workers. In other communities, such as crowdsourced innovation platforms, issues of confidentiality or intellectual property rights may make it difficult to involve external workers. Further, volunteers in the community may possess desirable levels of motivation and expertise that may be valuable for the crowdsourcing tasks. In these scenarios, it may be desirable to leverage the volunteers themselves for crowdsourcing tasks, rather than external workers.
A key challenge to leveraging the volunteers themselves is that in any reasonably complex activity (like collaborative ideation) there are exciting tasks to be done and there is other work that is equally important, but less interesting. In a paper to be presented at UIST’16, we demonstrated the integrated crowdsourcing approach that seamlessly integrates the potentially tedious secondary task (e.g., analyzing semantic relationships among ideas) with the more intrinsically-motivated primary task (e.g., idea generation). When the secondary task was seamlessly integrated with the primary task, our participants did as good a job on it as crowds hired for money. They also reported the same levels of enjoyment as when working just on the fun task of idea generation.
Our IdeaHound system embodies the integrated crowdsourcing approach in support of online collaborative ideation communities. This is how it works: The main element of the IdeaHound interface (below) is a large white board. Participants make use of this affordance to spatially arrange their own ideas and the ideas of others because such arrangement of inspirational material is helpful to them in their own ideation process.
Their spatial arrangements also serve as an input to a machine learning algorithm (t-SNE) to construct a model of semantic relationships among ideas:
In several talks last fall, we referred to this approach as “organic” crowdsourcing, but the term proved confusing and contentious.
Several past projects (e.g., Crowdy and the User-Powered ASL Dictionary) embedded work tasks into casual learning activities. Our work shows how to generalize the concept to a domain where integration is more difficult.
