A Web of Concepts

Summary: Proposes a “web of concepts” that extracts and stitches concept-centric metadata across pages into semantically rich representations of concept instances. Calls for domain-centric extraction beyond wrappers, discusses reconciliation challenges, and enables concept-aware search, attribute filters, and cross-page synthesis.
