Schema-As-You-Go: On Probabilistic Tagging and Querying of Wide Tables

Summary: Schema-As-You-Go proposes a tag-based semantic layer that separates user actions from database operations on wide, heterogeneous tables. Ingested values carry user-provided tags; queries interpret tag semantics to retrieve data, enabling flexible, vocabulary-free querying with proven effectiveness.
