Crowdsourcing

Provide short introduction here

General introduction to approach

Crowdsourcing is a participatory online activity in which participants voluntarily undertake a task in response to a call or request from a state institution, group, company, individual or non-governmental organisation etc. For example, residents might be asked to i) vote on which local park or other green space they think is most in need of renovation; ii) then suggest and discuss possible new designs or features of the park, before; iii) voting again on a list of final suggestions. Crowdsourcing might involve gathering data from engaged people, might be based on data gathered from sensors, or might be based on a combination of the two. Furthermore, crowdsourcing might involve quite closed or limited responses (e.g. voting on a list) or be relatively open (e.g. allowing for user generated categories or suggestions).

Crowdsourcing is one way in which complex problems can be solved by pooling the skills and resources of large numbers of people. If a particular project has many component parts, then it can be divided up with different groups of people tasked with working on the different elements. Groups involved in creating sustainable and just cities might be drawn to using crowdsourcing as an approach because, if introduced early in the process and designed in an open complex-embracing manner, it not only allows citizens to have their say within a pre-existing discussion in a rather passive manner, but can also allow citizens to shape the very grounds for discussion about their cities and environment. An example of a particularly open variant of crowdsourcing is the platform OpenIDEO, set up to help tackle the challenges faced by Detroit, USA. OpenIDEO works by issuing a ‘challenge’, which kickstarts a multi-step process: individuals submit ideas, these are grouped under themes, which then go through concept development (which may include combining themes or ideas), these fleshed out concepts are then voted on, refined, evaluated and then finally chosen.

There are multiple examples of different realisations of crowdsourcing projects, including: Collideoscope which utilizes participant generated data on collisions to make cycling safer in Europe. Stereopublic, a crowdsourced app that helps people find quiet spots in cities; EveryAware a project that combined data sensors and active user-generated content to help improve the environment through monitoring, awareness and finally behavioural change in different European cities; Cities4People which uses ‘citizen mobility kits’ as participative tools for designing mobility innovations in different European cities; and COBWEB, Citizen OBservatory WEB, a project in which everyday people collected environmental information via mobile phones for research, decision making and policy formation in Dyfi Biosphere Reserve area in mid-Wales.

Shapes, sizes and applications

Crowdsourcing can take different shapes and sizes. One possible way of categorising different modes of crowdsourcing is by the relationship between the crowd (users, participants, public) and the organiser of a particular project or initiative. From the most closed to the most open, there is -- crowd processing, where large amounts of similar data is gathered (e.g. an app that measures how many minutes people spend in a park each month); crowd rating, where large amounts of similar data is gathered and then assessed via ratings (e.g. voting for different options about how to renovate a park); crowd solving, where very different responses or data is gathered and assessed against existing criteria for evaluation (e.g. we need a park with disabled access, how can we do it); and crowd creation, where the final solution, value or choice is determined by its relationship to other suggestions (e.g. we have some space in the city, what should we do with it?). In reality, there is often a mix of different types of crowdsourcing at different stages in a particular project. Crowdsourcing has been used all over the world to solve many different challenges and thus has been tested, refined, critiqued and redeveloped.
