Locating Failure in Multi-Page Visually Rich Document Understanding: An Empirical Attribution
TL;DR
This study identifies three key failure modes in multi-page visually-rich document understanding systems: representation, selection, and reasoning. It reveals that while vision is essential, it cannot replace text extraction, and that reasoning often fails to integrate evidence across pages.
✦ Why It Matters
Evaluate your document understanding systems to ensure they effectively integrate visual and textual information.
Key Takeaways
- Assess representation, selection, and reasoning in your document understanding systems.
- Ensure text extraction complements visual data processing.
- Consider the impact of missing pages on accuracy.
- Experiment with prompting to enhance reasoning outcomes.
How It Works
The study employs a controlled experimental design to isolate the effects of representation, selection, and reasoning on document understanding performance. By manipulating one failure mode while keeping the others constant, the researchers can pinpoint specific weaknesses in the system's architecture.
