name: bench-debug description: Debug specific document parsing failures

/bench-debug <doc_id>

Compares parsing output with ground-truth for a specific document and analyzes failure causes.

Usage

Copy/bench-debug 01030000000189

Execution Steps

1. Run benchmark for the specific document

   Copy./scripts/bench.sh --doc-id <doc_id>
   

2. Compare files

   • Ground-truth: tests/benchmark/ground-truth/markdown/<doc_id>.md
   • Prediction: tests/benchmark/prediction/opendataloader/markdown/<doc_id>.md
   • Original PDF: tests/benchmark/pdfs/<doc_id>.pdf

3. Analyze differences

   • Missing/extra text locations
   • Table structure differences (TEDS score causes)
   • Heading level mismatches (MHS score causes)
   • Reading order errors (NID score causes)

4. Identify root causes

   • Which PDF elements caused the issue
   • Which Java core components are involved

5. Suggest improvements

   • Java classes/methods that need modification
   • Expected impact scope

Reference Files

• ground-truth/reference.json: Per-document element info (categories, coordinates, etc.)
• java/opendataloader-pdf-core/: Core parsing logic

Example Output

CopyDocument 01030000000189 Analysis:

Overall: 0.2763 (one of the worst performing documents)

Issues:
1. 2 of 3 tables not detected (TEDS: 0.15)
   - Table boundary detection failed
   - Related code: TableDetector.java

2. Reading order errors (NID: 0.45)
   - Multi-column layout handling failed
   - Related code: ColumnDetector.java

Recommended Actions:
- Adjust clustering threshold in TableDetector
- Improve multi-column detection logic
