Automatic Discovery of Language Models for Text Databases

Summary: DB selection service builds language models for text databases by sampling query results, removing the need for database-provided models. Carefully chosen queries approximate sampling, yielding accurate models from few queries and documents for GlOSS-driven cross-database discovery. (summarized by gpt-5-nano on Feb 09 2026)
