Business glossary boosts text-to-SQL agent accuracy, learned terms fail

By PulseAugur Editorial · [1 sources] ·

A text-to-SQL agent's performance significantly improved when provided with a comprehensive business glossary, demonstrating a 28-question gain in accuracy compared to using no glossary. However, a glossary that was automatically learned from past user questions showed no improvement, suggesting that manually curated terms are crucial for enhancing the agent's understanding of business-specific language and its ability to correctly map terms to database schemas. The tool, schemagate 1.2.0, also incorporates access control to prevent glossary terms from revealing sensitive table or column information to unauthorized users. AI

IMPACT Enhances the reliability of text-to-SQL agents by improving their understanding of domain-specific terminology, potentially reducing errors in data analysis.

RANK_REASON The item describes a specific software tool (schemagate) and its performance improvements with a new feature (business glossary).

    I gave my text-to-SQL agent a business glossary. One version helped a lot, one did nothing.

    <p>A text-to-SQL agent sees table and column names. It does not know that "revenue" in your company means <code>billing_invoice.total_net</code>, only for invoices with <code>status = 'issued'</code>. So it guesses, and the guess runs without errors and returns the wrong number.<…
