Social computing and user-generated content: a game-theoretic approach

Social computing is now ubiquitous on the Web, with user contributions on sites like online review forums, question-answer forums, wikis, or Youtube forming a growing fraction of the content consumed by Web users. But while there is plenty of user-generated content online, the quality of contributions and extent of participation vary widely across sites. We survey some recent work taking a game-theoretic approach to the problem of incentivizing high quality and participation in these social computing systems.
