|
| ## TL;DR |
|
|
| This is the **conservative XL-DocBench release**. It contains |
| **1,345 QA rows over 292 documents** after |
| removing every question that touches an exact source URL marked |
| `RAG: Not Approved`. |
|
|
| ## This release |
|
|
| **292 documents** · **1,191 single-document QA** · |
| **154 cross-document QA** · **1,345 total QA** |
|
|
| - `data/documents.jsonl`: retained document metadata and source URLs. |
| - `data/qa_single_doc.jsonl`: retained single-document questions. |
| - `data/qa_cross_doc.jsonl`: retained cross-document questions. |
| - `manifest.json`: recomputed release statistics. |
| - `results/scores.jsonl`: per-question scores for the 13 reproducible systems. |
| - `results/summary.json`: aggregate scores for the same systems. |
| - `code/quickstart.py`: one-command data and evaluator smoke test. |
| - `code/evaluate.py`: self-contained deterministic evaluator. |
|
|
| The filter uses exact URL matching. This variant addresses exact `Not Approved` |
| RAG rows only and does not interpret separate `Portions Approved` entries. |
|
|
| ## About XL-DocBench |
|
|
| XL-DocBench asks systems to **find the evidence, combine all required support, |
| apply the right rule, and know when to abstain**. This strict release contains |
| 1,345 expert-verified questions from six professional domains. Among 1,280 |
| records with parseable historical human page annotations, 975 (76.2%) use |
| multiple evidence pages. Released supporting evidence is multimodal for 429 |
| questions (31.9%), 154 questions (11.4%) use cross-document contexts, and 188 |
| require a `None` answer. Full-series contexts reach 2,935 pages. |
|
|
| ## Reproducible strict results |
|
|
| All systems below have complete scores for the 1,345 retained IDs and use the |
| hardened evaluator shipped in this release. |

|
| ## Per-question scores |
|
|
| Source documents are referenced by public URLs rather than redistributed. |
| Because some URLs may change or become unavailable over time, we also provide |
| the benchmark scores for every retained question ID. This gives future users a |
| stable comparison point even when a source URL is temporarily unavailable. |
|
|
| - `results/scores.jsonl`: one row for each of the 1,345 question IDs. |
| - `results/summary.json`: aggregate Accuracy, Token F1, and ANLS. |
|
|
| Scores are stored on a 0-to-1 scale. |
|
|
| ## Quick start |
|
|
| Validate the complete release and run a five-question evaluation fixture: |
|
|
| ```bash |
| uv run --no-project python code/quickstart.py |
| ``` |
|
|
| Load all three JSONL tables with the included standard-library example: |
|
|
| ```bash |
| uv run --no-project python code/examples/load_data.py |
| ``` |
|
|
| ## Evaluation |
|
|
| Try the bundled five-question example: |
|
|
| ```bash |
| uv run --no-project python code/evaluate.py \ |
| --gold-files code/examples/gold_sample.jsonl \ |
| --predictions code/examples/predictions_sample.jsonl |
| ``` |
|
|
| For a complete run, provide one prediction per question: |
|
|
| ```jsonl |
| {"question_id": "adubench_single_000001", "prediction": "the biggest single risk to human health worldwide"} |
| {"question_id": "adubench_cross_000001", "prediction": "macroprudential measures"} |
| ``` |
|
|
| ```bash |
| uv run --no-project python code/evaluate.py \ |
| --predictions predictions.jsonl \ |
| --output eval_report.json \ |
| --per-question-csv per_question.csv |
| ``` |
|
|
| The evaluator reports rule-based **Accuracy**, token-level **F1**, and **ANLS**. |
| Missing, failed, and unparsable predictions count as incorrect unless |
| `--ignore-missing` is enabled. |
|
|
| ## Record structure |
|
|
| ```text |
| question |
| ├── answer: value + format + verification rule |
| ├── document / documents |
| │ ├── document_id + public URL |
| │ ├── evidence_pages: one-based PDF/release page indices |
| │ └── evidence_items: annotator locator + page references + excerpt kind |
| └── metadata: domain + difficulty + reasoning type + answerability |
| ``` |
|
|
| `evidence_pages` locate pages in the released PDF context. Evidence-item |
| `pages` preserve annotator-supplied page references; printed pagination can |
| differ from PDF indices. The `page_numbering` and `evidence_kind` fields make |
| those cases explicit. Row-level `unassigned_evidence_items` are retained as |
| provenance and are not counted as released supporting evidence. |
|
|
| PDF binaries and local filenames are not included. Source documents remain |
| subject to their original licenses and terms; this release does not grant |
| redistribution rights for third-party PDFs. |
