HebOCRBench v1 — Modern Hebrew participant pack
This is the public, fixed evaluation-input pack for the five-track HebOCRBench 1.0 Modern Hebrew printed-document headline. It contains 34,267 images and opaque input records. It intentionally contains no transcription gold, original source identifiers, source URLs, private filenames, organizer ID map, or HMAC key.
The unchanged certified references are withheld from this repository. An organizer remaps submitted opaque identifiers and scores predictions against those references. Withholding the gold is an evaluation protocol: the source material is public-fixed, so this release does not claim that models have never seen it or that it is contamination-free.
Exact release identity
| Binding | Value |
|---|---|
| Benchmark version | 1.0.0 |
| Suite fingerprint | c68250ec4320485e243171b7d3f86c9b3b526f8ada317eda592cd7289f4df5ea |
| Participant-pack fingerprint | 957e3b4f05707155db407d6707d742c7fe459365f575febb963e9d5732c3913c |
| Suite-lock SHA-256 | 04709dd2a76882fdb02704134dba3b3dfcc59b90dc967147f1a3b31d6d70c9ef |
| Locked files | 34,275, plus PACK-LOCK.json |
| Image records | 34,267 |
| Sharding | two lowercase hex characters; maximum 139 images per directory |
The byte-locked pack is under participant-v1.0.0/.
Its public verification material is:
PACK-LOCK.json: SHA-256 and size for every locked file, plus the pack fingerprint;PACK-MANIFEST.json: release, track, count, sharding, and no-leakage declarations;suite-lock.json: the exact five-track suite binding.
The gold_sha256 values in the two public manifests are one-way integrity
bindings only. No reference text or reference structure is included.
Tracks
| Track | Inputs | Mode |
|---|---|---|
modern-bidi-v1 |
192 | Unicode/BiDi conformance with supplied geometry |
modern-line-recognition-v1 |
28,414 | line recognition with supplied geometry and opaque line IDs |
modern-page-ocr-v1 |
700 | blind end-to-end page OCR |
modern-tables-v1 |
61 | blind table detection, structure, spans, positions, and cell text |
modern-robustness-v1 |
4,900 | blind OCR on locked degradation pairs |
All Hebrew text in predictions must be in logical Unicode order. Do not mirror images or reverse Hebrew strings. Latin runs, numbers, URLs, email addresses, identifiers, and punctuation keep their ordinary internal order.
Download and verify
hf download ssdataanalysis/hebocrbench-v1 \
--repo-type dataset \
--local-dir hebocrbench-v1
cd hebocrbench-v1/participant-v1.0.0
jq -r '.files[] | "\(.sha256) \(.path)"' PACK-LOCK.json \
| shasum -a 256 --quiet -c -
The checksum command exits with status 0 only when every locked file has the
declared bytes. PACK-LOCK.json itself declares the participant-pack
fingerprint shown above.
Run a model and prepare predictions
For each track, read:
participant-v1.0.0/tracks/<track-id>/inputs.jsonl
Resolve each image.path relative to participant-v1.0.0/. Write one JSON
object per input line to a separate prediction JSONL for that track. Copy the
opaque page_id exactly and include schema_version: "1.0" and track_id.
At minimum, emit the fields required by the selected task:
- BiDi and line recognition: preserve the supplied opaque region/line IDs and
add recognized
textin their lines; - blind page OCR and robustness: emit discovered
regions, line text, andreading_order; - tables: emit detected
tablesand their cells, spans, positions, geometry, and logical-order cell text.
Example envelope (the exact nested fields depend on the track):
{"schema_version":"1.0","track_id":"modern-page-ocr-v1","page_id":"hbo-v1-p-…","regions":[],"reading_order":{"edges":[]},"tables":[]}
A submission must contain exactly one prediction for every page in the track; unknown, duplicate, or missing opaque page IDs are rejected. The prediction schema, track contracts, organizer remapping tool, official scorer, and reproducibility documentation live in the HebOCRBench code repository.
What this pack does not cover
This release is only the five-track Modern Hebrew print headline. It does not blend scientifically different families into one score. The full suite also records separate real-data extensions for writer-disjoint modern handwriting, a narrow six-page Pinkas handwriting subset, and 34 pages of mixed square/Rashi HaZefira historical press. Synthetic niqqud and single-font Rashi probes are non-rankable diagnostics.
The following remain explicit missing real-data coverage in v1:
- forms with field-level ground truth;
- Biblical Hebrew with real cantillation ground truth aligned to scans;
- pure-Rashi historical print with region- or line-level Rashi labels.
No score from this pack should be presented as a handwriting, Biblical, cantillation, historical-print, or pure-Rashi result.
Provenance and terms
HebOCRBench software is MIT-licensed. That code license does not relicense the images in this dataset. Each source document retains its own terms, rights, and attribution requirements. The benchmark build records revision-locked acquisition evidence, hashes, page counts, provenance, and source-specific terms; upstream identities and URLs are deliberately omitted from this blind participant pack. Consult the code repository's source and license audit before redistributing or using source images beyond benchmark evaluation.

עברית בקצרה: זהו מארז הקלט הציבורי והנעול של חמשת מסלולי הדפוס העברי המודרני. ה־gold נשמר בנפרד, המזהים אטומים, וכל תוצאה חייבת לציין את טביעות האצבע המדויקות של ה־suite וה־pack. אין להציג תוצאה ממנו כתוצאת כתב־יד, מקרא עם טעמים או Rashi היסטורי טהור.
