DTBench: A Synthetic Benchmark for Document-to-Table Extraction

arXiv:2602.13812v3 Announce Type: replace-cross Abstract: Document-to-table (Doc2Table) extraction derives structured tables from unstructured documents under a target schema, enabling reliable and verifiable SQL-based data analytics. Although large language models (LLMs) have shown promise in flexible information extraction, their ability to produce precisely structured tables remains insufficiently understood, particularly for indirect extraction that requires complex capabilities such as reasoning and conflict resolution. Existing benchmarks neither explicitly distinguish nor comprehensivel

Why this matters
Why now

The proliferation of LLMs and the increasing need to extract structured data from unstructured documents for analytics is driving the creation of specialized benchmarks like DTBench.

Why it’s important

This benchmark addresses a critical gap in evaluating LLMs' ability to accurately extract structured tables, which is fundamental for reliable data analytics and automating information processing.

What changes

The development of DTBench provides a more robust and explicit methodology for assessing LLMs in complex document-to-table extraction tasks, leading to more capable and verifiable AI systems.
