Crowdsourcing (Howe, 2008) is the term of used for methods of data creation, where large groups of users who are not organised centrally generate content that is shared. From direct public involvement via citizen science initiatives, such as the well documented Galaxy Zoo, through to simply tapping into online data feeds, we are arguably in a new era of volunteered information and knowledge creation.
The notion that there might be value in harvesting the knowledge of individuals is based on the observation that, although large in number of individual estimates may be incorrect, their average can be a match for expert judgment.
