Pushing the Boundaries of Crowd-enabled Databases with Query-driven Schema Expansion
Summary: Extends crowd-enabled databases with query-driven schema expansion for on-demand attributes. It leverages perceptual spaces learned from social web ratings and few expert samples to automatically infer missing data, reducing crowdsourcing cost while maintaining high quality.
