| # Doc-Split Benchmark |
|
|
| The **evaluation slice** for page-stream segmentation — the exact set behind the |
| [leaderboard](https://huggingface.co/spaces/nutrientdocs/doc-split-leaderboard) and the cloud-VLM |
| comparison. Self-contained (page images embedded), with a reference scorer so results are reproducible. |
| This is the *benchmark*, not the training corpus (which stays private). |
|
|
| - 🏆 **Leaderboard:** [doc-split-leaderboard](https://huggingface.co/spaces/nutrientdocs/doc-split-leaderboard) |
| - 🎯 **Demo:** [doc-split-demo](https://huggingface.co/spaces/nutrientdocs/doc-split-demo) |
| - 🟢 **Model:** [doc-split-mini-e5](https://huggingface.co/nutrientdocs/doc-split-mini-e5) (open weights) |
| - 🌍 **OpenPSS cuts:** [openpss-mirror](https://huggingface.co/datasets/nutrientdocs/openpss-mirror) (SHORT/LONG, self-contained) |
|
|
| ## Cuts |
|
|
| | Cut | Where | Notes | |
| |---|---|---| |
| | **our-200** | this repo (`our200` config) | 200 license-clean synthetic-concat streams, ~78% boundary rate | |
| | **OpenPSS short / long** | [openpss-mirror](https://huggingface.co/datasets/nutrientdocs/openpss-mirror) | Dutch; sparse- & dense-boundary regimes | |
| | TABME++ / Tobacco800 | upstream (not redistributed) | reported for reference; licenses/gating prevent re-hosting | |
|
|
| ## Load |
|
|
| ```python |
| from datasets import load_dataset |
| ds = load_dataset("nutrientdocs/doc-split-benchmark", "our200", split="test") |
| # one row = one page; group by stream_id, order by position. |
| ``` |
|
|
| ## Schema |
|
|
| | Field | Type | Meaning | |
| |---|---|---| |
| | `stream_id` | string | groups pages into one ordered stream | |
| | `position` | int | page index within the stream (0-based) | |
| | `boundary` | int | **1 = starts a new document** (position 0 always 1) | |
| | `page_text` | string | page OCR text (may be empty) | |
| | `image` | image | page image (512px) | |
| | `source` | string | provenance | |
|
|
| ## How to score |
|
|
| Metric: **boundary page-F1** (internal positions, page 0 forced) + Cohen's **κ**, WindowDiff, Pk. |
| The reference scorer ships in this repo: |
|
|
| ```bash |
| python score.py --pred your_preds.json # preds: {stream_id: [0/1 per page]} |
| ``` |
|
|
| `score.py` uses `docsplit.eval.metrics.aggregate` (bundled). κ is reported because a degenerate |
| predict-none/all can look fine on F1 but scores κ ≈ 0 on the sparse cuts. See `SUBMISSION.md` to add a row to |
| the leaderboard. |
|
|
| `manifest.json` records provenance (per-source stream/page counts, boundary rates, seed). |
