MPDocBench-Parse: Benchmarking Practical Multi-page Document Parsing

· Source: cs.AI updates on arXiv.org · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Data Science & Analytics · Depth: Expert, extended

Summary

MPDocBench-Parse is a new benchmark designed to address the limitations of existing document parsing benchmarks, which are often inadequate for realistic multi-page scenarios. Developed by the University of Science and Technology of China and Tongyi Lab, Alibaba Group, it features 433 manually annotated documents across 3,246 pages, covering 15 diverse document types in both English and Chinese with varied layout styles. The benchmark supports document-level end-to-end evaluation and introduces a comprehensive protocol for assessing content fidelity and logical structure. This includes text, table, and formula recognition, truncated text and table merging, figure extraction, reading order, and heading hierarchy recovery. Experiments reveal that while current models excel at basic text extraction, they show clear limitations in semantic continuity integration, visual content parsing, and hierarchical structure recovery.

Key takeaway

For AI Engineers developing document parsing solutions for enterprise applications, recognize that current models, including general VLMs, still exhibit significant limitations in handling realistic multi-page documents. Your evaluation strategies should extend beyond basic text extraction to rigorously test semantic continuity, multimodal visual content extraction, and hierarchical structure recovery. Prioritize specialized models and research efforts that explicitly address these complex challenges to ensure robust real-world deployment.

Key insights

Practical multi-page document parsing requires benchmarks assessing semantic continuity, visual content, and hierarchical structure beyond basic text.

Principles

Method

MPDocBench-Parse uses iterative annotation with model pre-annotation, human correction, and multi-dimensional verification for structure and content, including a Gemini-3-Pro refinement step for OCR.
