DOCS: Domain-Aware Crowdsourcing System

Summary: DOCS models worker quality as domain-dependent rather than task-independent, deriving task/worker domains from knowledge bases. It combines domain-aware truth inference with online worker assignment, improving crowdsourcing accuracy over prior methods. (summarized by gpt-5.6-luna on Jul 24 2026)
