Sato: Contextual Semantic Type Detection in Tables

Summary: Sato detects column semantic types by using table-context signals with column values. A hybrid model fuses deep learning on table corpora, topic modeling, and structured prediction, delivering F1 0.925 (support-weighted) and 0.735 (macro), surpassing prior work.
