CyLog/Crowd4U: A Declarative Platform for Complex Data-centric Crowdsourcing
Summary: Crowd4U is a declarative platform for data-centric human/machine computation, built around CyLog, a Datalog-like abstraction. CyLog integrates human feedback and game-theoretic semantics, enabling principled design and analysis of complex crowdsourcing workflows. (summarized by gpt-5.6-luna on Jul 24 2026)
