Querying Heterogeneous Information Sources Using Source Descriptions

Summary: Information Manifold provides uniform access to 100+ heterogeneous web sources via declarative source descriptions. It prunes candidate sources and generates executable query plans, with experiments demonstrating scalability to several hundred sources. (summarized by gpt-5-nano on Feb 09 2026)
