Extracting and Querying a Comprehensive Web Database
Summary: Omnivore builds a comprehensive web-scale entity-relationship DB by running multiple domain-independent extractors (tables, text, relations) in parallel over a crawl and merging heterogeneous outputs to overcome model-specific blind spots. Provides SQL-like and search interfaces, supports user corrections, and automatically selects output model/schema to render results without prior metadata. (summarized by gpt-5-mini on Feb 09 2026)
