Metadata in a Crowd: Shared Knowledge Production
The document discusses human computation and how crowdsourcing can be used to generate metadata. It describes different models of human computation, including socially motivated tasks like tagging photos on Flickr, economically motivated tasks on Amazon Mechanical Turk, and tacit tasks like reCAPTCHAs. The document also discusses how human computation draws on human abilities at visual and language tasks to solve problems in parallel in a way similar to bittorrent networks. It argues that successful systems motivate participation through incentives, games, or the ability to contribute to a collective knowledge base.
