Dataset Card for StructBench
Dataset Summary
StructBench is a benchmark for evaluating fine-grained document structure analysis. It provides a high-quality test set of 248 documents in diverse formats, including 203 Web pages and 47 PDFs.
To ensure reliable ground truth, all documents were:
Parsed and sentence-segmented
Manually annotated by human experts for discourse structure
In addition to the structured annotations, raw Web pages and PDF files are included.
Dataset Structure
- test/: evaluation-only split
- data.parquet: data samples
- raw_pdf_files/: original PDF files
- raw_web_htmls/: original WEB htmls
Tasks
- Discouse Analysis
- Document Structure Parsing
- Document Understanding
Usage
Clone the dataset:
git clone https://huggingface.co/datasets/deeplang-ai/StructBench
Or load with Hugging Face datasets library:
from datasets import load_dataset
dataset = load_dataset("deeplang-ai/StructBench", split="test")
