Table Union Search on Open Data

Summary: Proposes probabilistic table union search for Open Data to find unionable tables via shared attribute domains. Three models (set-domain, ontology semantic, NL-domain), a per-pair data-driven selector, and a distribution-aware union-size algorithm; open benchmark with scalable results to 1M+ attributes.
