SEMA-JOIN: Joining Semantically-Related Tables Using Big Table Corpora
Summary: SEMA-JOIN automates semantic joins beyond equi-joins by mining a big table corpus (>100M tables) to learn row- and column-level correlations. Join discovery is framed as maximizing aggregate correlation with a linear-program relaxation and a 2-approximation, yielding high precision on public and enterprise data.
