In crowdsourcing paradigm, tasks are distributed to networked people to complete such that a company's production cost can be greatly reduced. In 2003, Luis von Ahn and his colleagues pioneered the concept of "human computation", which utilizes human abilities to perform computation tasks that are difficult for computers to process. Later, the term "crowdsourcing" was coined by Jeff Howe in 2006. Since then, a lot of work in crowdsourcing has focused on different aspects of crowdsourcing, such as computational techniques and performance analysis. In this paper, we give a survey on the literature on crowdsourcing which are categorized according to their applications, algorithms, performances and datasets. This paper provides a structured view of the research on crowdsourcing to date. © 2011 IEEE.enOnline HealthOnline Health CommunitiesStudy Of Social InteractionsSocial NetworksSupporting InformationOnline CommunitiesSocial Networking SitesPearson CorrelationSocial SupportStrength Of AssociationEmotional SupportInformation QualityHuman-Computer InteractionHealth DomainsDegree DistributionSocial Network AnalysisInstrumental SupportPercentage Of UsersInformation-Seeking BehaviorPair Of NetworksSocial Network UsersForum UsersJournal FormatTypes Of Social SupportPost MessagesProfile PageOnline Discussion BoardHealth ProblemsCommunity Social NetworksConference Paper10.1109/PASSAT/SocialCom.2011.36
