ParseBench is a dataset of 2000 pages from 1100 documents, primarily drawn from “enterprise domains” like finance, legal, and government.

The 5 Tasks of ParseBench

1. Table Structure
2. Chart Derendering
3. Layout Detection (Visual Grounding)
4. Content Faithfulness
5. Semantic Formatting (strikethrough, bold, underline, etc.)

Unit Tests and Construct Validity

ParseBench isn’t the first document processing benchmark to rely on unit tests. OlmOCR-bench, from AllenAI, also relies on unit tests. In their case for ordering, presence or absence of content, and formula rendering.
