Mining a Search Engine’s Corpus: Efficient Yet Unbiased Sampling and Aggregate Estimation
Summary: Unbiased sampling and online aggregate estimation over a search-engine corpus accessible only via keyword queries. Proposes provably unbiased, low-variance methods with an order-of-magnitude lower query cost, validated by theory and experiments. (summarized by gpt-5-nano on Feb 09 2026)
