DTT: An Example-Driven Tabular Transformer for Joinability by Leveraging Large Language Models

Summary: DTT: an example-driven tabular transformer for joinability across heterogeneous formats. Few-shot mappings learned by fine-tuned LLMs yield accurate joins, missing-values, and error detection; outperform traditional approaches and rival GPT-3. (summarized by gpt-5-nano on Feb 09 2026)
