Which Concepts Are Worth Extracting?
Summary: Introduces cost-effective conceptual design: selecting a budget-limited subset of concepts to annotate to boost query effectiveness. Proposes APM and AAM with provable guarantees (APM PTAS without overlap; constant-factor when concepts are exclusive; AAM PTAS for exclusive concepts); experiments on Wikipedia and query logs validate performance and guide choice.
