Distributed Search over the Hidden Web: Hierarchical Database Sampling and Selection

Summary: Proposes metasearch over hidden-web databases via adaptive probes to produce content summaries with absolute word-frequency estimates. Introduces a hierarchical selection algorithm using these summaries and an induced taxonomy to surpass flat methods, validated on 50 real databases. (summarized by gpt-5-nano on Feb 09 2026)
