Social-purpose Crowdsourcing

Crowdsourcing aimed at achieving a social or public-benefit goal rather than producing paid labour or commercial output. Examples include volunteer proofreading for accessible-book libraries, crowdsourced captioning, alternative-text generation, OCR error correction for historical archives, and citizen-science projects. Social-purpose crowdsourcing typically relies on unpaid volunteers and intrinsic motivations (Social Contribution, Community Identification, Personal Interest) rather than monetary payment, and so requires different system design — community portals, collective progress feedback, and meaningful framing of the social goal — to sustain participation.
