unstructuredio/SCORE-Bench

Dataset Description

SCORE-Bench is a curated collection of 224 diverse, real-world documents manually annotated by experts. It is designed to benchmark document parsing systems against true production-grade challenges. Unlike traditional academic datasets often composed of clean, digital-native PDFs, this benchmark specifically targets the complexity found in actual enterprise workflows.

Note on replication: This dataset is a standalone benchmark released after the publication of the original SCORE framework paper. It is not the exact dataset used in the paper's experiments. Researchers should view this as a new, more challenging evaluation set using the same methodology. The dataset allows researchers and developers to move beyond "clean" evaluation to test how systems handle the irregularities of the real world. It includes:

• Complex Layouts: Financial reports with deeply nested tables, technical manuals with multi-column dense text, and articles where whitespace (rather than lines) defines structure.
• Visual Noise & Variety: Scanned forms with skew, photocopied documents with artifacts, and forms containing mixed printed and handwritten text.
• Semantic Ambiguity: Documents selected to break brittle systems, requiring parsers to distinguish between varying structural interpretations (e.g., identifying a two-column article versus a list of key-value pairs).

Every document in SCORE-Bench has been manually annotated by domain experts, not algorithmically generated from metadata.

Dataset Coverage

Distribution of document layout characteristics
Each document typically presents more than one of the characteristics:

Document characteristic	Count
Scanned documents	54
Documents with noise and visual degradation	39
Multi-column layout	98
Flowing text blocks	143
Complex layout	127
Simple tables	40
Complex tables with merged cells	48
Embedded images or plots	81
Forms	54
Handwriting mixed with printed text	33
Layout with complex visual branding	114

Document content types

The dataset captures the heterogeneity of real-world unstructured data not only across verticals, but also across document types. It includes operational and regulatory content: government reports, financial statements, legal agreements, insurance forms, and technical manuals alongside lower-frequency but operationally critical artifacts such as patent documents, research papers, curriculum vitae, marketing collateral, schematics, and more. This breadth ensures that evaluation can be done on content representative of real-world enterprise workflows: complex unstructured documents that span both common and occasional niche types. By incorporating this long tail of document types, the dataset reflects the diversity and functional richness encountered in actual organizational settings, providing a realistic benchmark for document parsing.

Annotation Format

The dataset uses the following types of ground truth data:

1. Text Content Ground Truth: Content is structured with markers for different document elements, enabling evaluation against a clean concatenated text representation (CCT).

--------------------------------------------------- Unstructured Plain Text Format 1

--------------------------------------------------- Unstructured Title Begin
DOCUMENT TITLE
--------------------------------------------------- Unstructured Title End

--------------------------------------------------- Unstructured NarrativeText Begin
Document content...
--------------------------------------------------- Unstructured NarrativeText End

2. Table Ground Truth: Tables are represented as JSON with cell coordinates and content, serving as the ground truth for our format-agnostic table evaluation

[
  {
    "type": "Table",
    "text": [
      {
        "id": "cell-id",
        "x": 0,
        "y": 0,
        "w": 1,
        "h": 1,
        "content": "Cell content"
      },
      ...
    ]
  }
]

Intended Usage

This dataset is designed to serve as a standardized benchmark for evaluating modern document parsing systems. Its composition specifically addresses the limitations of traditional metrics when applied to generative models. The intended use cases include:

• Fair Benchmarking of Generative Systems: The dataset intentionally contains layouts with multiple valid structural interpretations. The annotations are constructed to allow the SCORE system to evaluate based on semantics, ensuring that Vision Language Models (VLMs) are not penalized for legitimate interpretive flexibility (e.g. distinct but semantically equivalent readings of a complex page).
• Format-Agnostic Comparison: The ground truth allows for the comparison of outputs across varying representational formats (e.g., HTML, JSON, flattened text) by validating semantic equivalence rather than rigid string-level or tree-level matching.
• Granular Error Analysis: The variety of noise and document types enables the SCORE framework to identify specific system behaviors, such as distinguishing between content hallucinations (spurious tokens) and content omissions.
• Complex Table Evaluation: The data includes tables with ambiguous structures, merged cells, and irregular layouts to test extraction capabilities. This supports evaluation that separates content accuracy from index/spatial accuracy.
• Structural Hierarchy Assessment: The documents are selected to challenge a system's ability to maintain consistent, semantically coherent hierarchies (e.g., mapping headers and list items correctly) across long or complex pages.
