Deco: A System for Declarative Crowdsourcing

Summary: Deco enables declarative crowdsourcing by treating crowd data as a relation with relational data, queried by SQL. A push-pull hybrid executor enables data models, precise semantics, latency-cost-uncertainty tradeoffs, with MTurk and in-house platforms. (summarized by gpt-5-nano on Feb 09 2026)
