# Polish Language Document Layout Detection — Test A

PolEval 2026 task: find the layout regions on scanned Polish document pages and label each with one of 11
categories: Caption, Footnote, Formula, List-item, Page-footer, Page-header, Picture, Section-header, Table, Text,
Title. Page images and the task description: https://github.com/poleval/2026-document-layout

The inputs list one page per line:

- `id`: the page identifier a submission must use.
- `image_id`: the page's COCO image id.
- `file_name`: the page image in the organisers' repository, relative to `poleval_doclaynet_coco_test_a/`.
- `width`, `height`: the coordinate frame boxes are given in.

Submissions are one JSONL line per page, `{"id": "<page id>", "output": [{"category", "bbox": [x, y, w, h],
"score"}]}`. They are scored by COCO mAP@[.50:.95], the mean of the 11 per-category APs.

The data is converted from the organisers' COCO files without changing any value. 37 pages are listed as 1×1, with
fractional box coordinates, exactly as the organisers published them.
