| ## Original work |
| **OpenPSS: An Open Page Stream Segmentation Benchmark** — Ruben van Heusden, Jaap Kamps, Maarten Marx |
| (University of Amsterdam, IRLab), *TPDL 2024* (DOI [10.1007/978-3-031-72437-4_24](https://link.springer.com/chapter/10.1007/978-3-031-72437-4_24)). |
| Builds on **WooIR** (van Heusden, Kamps, Marx, *SIGIR ICTIR 2022*). |
|
|
| ## What this is |
| **Page Stream Segmentation (PSS):** given a stream of concatenated scanned pages, recover the original |
| document boundaries. OpenPSS provides two datasets — **SHORT** and **LONG**. The source documents are |
| Dutch government records released under the Freedom of Information Act (*Wet open overheid* / Woo), which |
| are public records. |
|
|
| This is a **self-contained, HuggingFace-native reformatting** of the original OpenPSS release (page images |
| embedded — no external `png.zip` to unpack), exposed as two loadable **configs** with train/test splits: |
|
|
| ```python |
| from datasets import load_dataset |
| short = load_dataset("nutrientdocs/openpss-mirror", "SHORT") # or "LONG" |
| # columns: stream_id (str), position (int, 1-indexed page in the stream), |
| # image (PIL), text (OCR), label (int: 1 = starts a new document / boundary, else 0) |
| ``` |
| A stream's ground-truth boundaries are the `label` column ordered by `position`; `label[0]` (page 1) is 1 |
| by construction. Content is faithful to the original OpenPSS SHORT/LONG; only the packaging is changed. |
