|
|
|
| ### Version details
|
|
|
| #### v0.2.5 — current stable
|
|
|
| Added three sources, bringing the complete release to **20 sources,
|
| 4,366,651 documents / 9,676,513,980 cl100k-proxy tokens**:
|
|
|
| - `samorzad_gov_pl`: **72,771 documents / 41,154,506 cl100k-proxy
|
| tokens** from 246 Polish local public institutions and one central platform
|
| tenant. The contribution preserves the publishing institution as `author`,
|
| discovered and fetched article URLs in an attribution sidecar and the verified
|
| platform-wide CC-BY-SA-4.0 basis.
|
| - `sejm_api`: **38,812 documents / 36,335,587 cl100k-proxy tokens** of
|
| parliamentary speeches (2023 onward) from the official Sejm API,
|
| `public-domain (official documents)`
|
| ([PR #16](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/16)).
|
| - `wiktionary_examples`: **8,639 documents / 1,115,820 cl100k-proxy tokens**
|
| of Polish Wiktionary usage examples, one document per headword,
|
| `CC-BY-SA-3.0`
|
| ([PR #14](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/14)).
|
|
|
| Documentation correction: the v0.2.5 tag contains all 20 sources. Earlier
|
| copies of this card counted only 18 (4,319,200 documents / 9,639,062,573
|
| tokens) and listed `sejm_api` and `wiktionary_examples` as not released.
|
|
|
| #### v0.2.4 — previous stable
|
|
|
| Expanded `european_hplt_v3_pl` from WDS bins 10+9 to **WDS bins 10-5** (added
|
| quality bins 8/7/6/5 and further WDS-9 shards): **+1,493,384 documents /
|
| 2,043,141,874 cl100k-proxy tokens**, 100% CC0-1.0. Includes a phone PII-scrub
|
| hardening pass (v12b) verified by two independent lenses (a systematic
|
| recall-gap masked by pipeline self-report was caught pre-release), and
|
| cross-source deduplication against the existing WDS-10+9 shards (exact-dup 0,
|
| near-dup overlap 0.0000%, byte-verified) — resolving the "downstream near-dedup
|
| remains" caveat from the original release.
|
|
|
| #### v0.2.3 — previous stable
|
|
|
| Community expansion release. Adds `european_hplt_v3_pl` from
|
| [PR #5](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/5)
|
| and `global_voices` from
|
| [PR #7](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/7),
|
| plus `nkjp1m` from
|
| [PR #8](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/8).
|
| The complete 16-source release contains **2,710,974 documents /
|
| 6,881,277,362 cl100k-proxy tokens**, summed from the released per-source parquet
|
| statistics.
|
|
|
| #### v0.2.2 — previous stable
|
|
|
| Added `govpl` from
|
| [PR #9](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/9):
|
| 88,190 Polish government press releases collected directly from 133 gov.pl
|
| ministry and agency subsites.
|
|
|
| #### v0.2.1 — previous stable
|
|
|
| Introduced the canonical eight-column release schema:
|
| `id, text, source, added, created, token_count, license, author`. Added
|
| `1000_novels` from
|
| [PR #1](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/1)
|
| and recomputed all release statistics from parquet files.
|
|
|
| #### v0.2.0 — initial stable corpus
|
|
|
| The provenance-first baseline: 11 reviewed open or official sources,
|
| 2,490,773 documents and 6.22B proxy tokens.
|
|
|
| #### v0.3-dev — experimental quality workflow
|
|
|
| Candidate-only work on a better-balanced training mixture: legal-source caps,
|
| temperature sampling, source QA, deduplication and direct-upstream ingestion.
|
| It is not a replacement for the stable corpus.
|
|
|
| #### Europeana validation artifact — 2026-07-10
|
|
|
| A separate reproducible 810-document Europeana sample preserving per-record
|
| rights and creator metadata. It does not change stable-release totals.
|
| `v0.3.1-preview` remains only as the legacy storage-path label.
|
|
|
| ## What this dataset contributes
|
| The raw texts come from existing open corpora (redistributed via SpeakLeash and,
|
| where applicable, fetched from upstream). **The value added here is the curation,
|
| not the bytes**, following the Dynaword methodology:
|
|
|
| 1. **License review per source** — each source vetted for an *openly-licensed,
|
| traceable* legal basis (documented in its datasheet); sources that fail the
|
| review are **excluded with a stated reason** (see table below), not silently
|
| kept. This is the core editorial work.
|
| 2. **Filtering & normalization** — minimal, reproducible gates (short-doc,
|
| non-Polish, exact cross-source dedup, OCR garble) applied uniformly to one
|
| clean schema: `id, text, source, added, created, token_count, license, author`.
|
| 3. **Documentation** — a datasheet per source (Gebru et al. 2021) + this card,
|
| so provenance and licensing are auditable rather than assumed.
|
| 4. **Reproducibility & versioning** — `src/` rebuilds the corpus from sources;
|
| new sources and removals are tracked in the CHANGELOG.
|
|
|
| Credit for the underlying texts belongs to the upstream sources and to SpeakLeash
|
| as the redistributing aggregator; this release does not claim ownership of them
|
| (see Disclaimer).

| Contributions are credited when they add a verifiable dataset artifact, pipeline,

|
|
|
| ## Guiding principles
|
| 1. **Open & traceable licensing** — every source is *openly licensed* with a documented
|
| legal basis (see each datasheet's "traceable basis"), not a vague "public domain".
|
| 2. **Reproducibility** — `src/build_dynaword.py` rebuilds the corpus from sources.
|
| 3. **Documented** — a datasheet per source under `data/<source>/`.
|
| 4. **Extensibility** — versioned; new sources via PR.

|
| This table is the v0.2.5 release as tagged (load it with `revision="v0.2.5"`).
|
| Main has changed since:
|
|
|
| - `european_hplt_v3_pl` was removed from main (licence under review; it is
|
| re-added only after that review).
|
| - `samorzad_gov_pl` was rebuilt from the de-identified upstream v0.2:
|
| 72,472 documents / 40.0M tokens
|
| ([PR #46](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/46), scoped from [PR #15](https://huggingface.co/datasets/SlayerLab/polish-dynaword/discussions/15)).
|
|
|
| The 19 v0.2.5 sources still on main total 2,762,378 documents / 7,119.8M tokens.
|
|
|
| ## Sources on main, not yet released
|
| Built and documented, but **not** part of v0.2.5 and excluded from every total
|
| above. None has a recorded [NERGAL](https://huggingface.co/SlayerLab/NERGAL)
|
| pass yet, which a source needs before a release can admit it (see `AGENTS.md`).
|
| `common_voice_pl` documents are single validated sentences (at most 153
|
| characters, below the 200-character document gate); whether sentence-level
|
| units are accepted is an open maintainer decision (see its datasheet).

|
| ## Method
|
| Only **human-authored** text — no synthetic, machine-translated, or auto-transcribed
|
| data. Gates are intentionally minimal (drop short docs, non-Polish, exact duplicates,
|
| OCR garble); heavy quality filtering and mix-weighting are left to downstream training.
|
| Evaluation-set decontamination is applied/marked separately. Schema:
|
| `id, text, source, added, created, token_count, license, author`. The `license`
|
| and `author` columns are per-document metadata when upstream exposes them; older
|
| sources use the source-level license and an empty author field.
|
|
|
| ## v0.3 quality roadmap and current status
|
|
|
| The v0.2.x raw corpus is intentionally provenance-first, but its token mix is too
|
| heavy in legal/parliamentary language for natural general pretraining. The v0.3
|
| workflow therefore separates **source inclusion** from **training mix**:
|
|
|
| - cap `eurlex + parliamentary + dziennik_ustaw` to roughly **10-20%** of training
|
| tokens combined;
|
| - use source-level temperature sampling (`sqrt`, alpha `0.5`) instead of raw
|
| token-proportional sampling;
|
| - add traceably licensed contemporary/natural Polish: open web, academic prose,
|
| cultural heritage text, guides, technical documentation/blogs, Q&A, and
|
| dialogue/instruction data;
|
| - run aggressive exact, normalized, and near-duplicate removal;
|
| - reserve the final **5-15%** of training for higher-quality sources rather than
|
| the largest sources;
|
| - evaluate per-source perplexity and style contamination, not only global loss.
|
|
|
| Current v0.3 source-ingestion status:
|
|
|
| - `biblioteka_nauki`: included from the direct-upstream rebuild with
|
| per-document license and author metadata.
|
| - `europeana`: prepared in the source registry as a direct-upstream rebuild
|
| target with per-record rights statements and creator metadata; raw SpeakLeash
|
| Europeana remains excluded.
|
| - Europeana release policy: split conservatively at pre-1929 records for
|
| US-sensitive downstream reuse, and keep later/unknown records separately
|
| labeled or held until legal review.
|
| - `european_hplt_v3_pl`: WDS bins 10-5 shipped in v0.2.4 and v0.2.5, then the
|
| data was removed from main because its licence is unverified: HPLT packaging
|
| is CC0, but the underlying crawled web documents can carry independent rights.
|
| It is re-added only after licence review.
|
|
|
| Current review artifacts:
|
|
|
| - `configs/source_candidates_v0_3.json` — candidate decisions and license policy.
|
| - `artifacts/source_license_review_v0_3.md` — source-by-source license review.
|
| - `artifacts/source_candidate_audit_v0_3.md` — generated Hugging Face metadata audit.
|
| - `artifacts/training_mix_v0_3.md` — example 1B-token training mix with legal sources capped at 15%.
|
| - `artifacts/bartek_source_ingestion_plan_2026-07-02.md` — PR contract for
|
| Biblioteka Nauki and Europeana ingestion.
|
|
|
| ## Excluded sources (transparency)
|
| Sources we reviewed and **deliberately left out** — part of the curation:
|
|
|
| | source | reason |
|
| |---|---|
|
| | `open_subtitles_corpus` | Derivative of copyrighted film/TV dialogue; OpenSubtitles uploads largely unlicensed. Same copyright lesson as Danish Gigaword's OpenSubtitles (paper 2508.02271). Not openly licensed. |
|
| | `europeana_eu_pl_corpus_raw_speakleash` | Aggregated items with mixed per-record rights (PD / CC-BY-NC / rights-reserved). The raw SpeakLeash redistribution is excluded; only a direct rebuild preserving per-record rights metadata may be included. |
|
| | `1000_novels_corpus_CLARIN-PL` | CC-BY-4.0 label, but 'novels' likely include in-copyright contemporary works; verify titles/years on CLARIN handle 11321/312 before inclusion. |
|
| | `project_gutenberg_pl_corpus` | Only 31 PL books (4.3MB) — PG is ~99% English; Polish PD literature already covered by wolne_lektury + wikisource (so near-redundant after dedup). Dropped to avoid the PD-in-EU per-work check (PG claims PD-in-US only) for negligible token gain. |
|
|
|
| ## Personal & sensitive data
|
| This corpus contains **only** text that its upstream sources already published
|
| under open licenses or as official public-domain record. It therefore includes
|
| names and statements of **public figures acting in a public capacity** — e.g.
|
| parliamentary speakers (PPC), authorities named in legal acts (EUR-Lex), and
|
| people described in encyclopedic articles (Wikipedia/Wikisource). No private,
|
| non-public personal data was collected or added. If you are a data subject and
|
| want content concerning you removed, contact **k.wikiel@gmail.com** — it will be dropped
|
| from the next version (see retroactive-removal policy below).
|
|
|
| ## Disclaimer & legal
|
| - **Provenance in good faith.** Per-source licenses are reproduced *as documented
|
| by the upstream sources and by SpeakLeash* (the intermediate aggregator), to the
|
| best of our knowledge. We make no independent legal warranty about the copyright
|
| status of any individual document.
|
| - **No ownership claim.** This release is a *curated, license-reviewed, documented
|
| aggregation*. We claim no ownership of the underlying texts; rights remain with
|
| the original authors/rightsholders under their respective licenses.
|
| - **Provided "as is"**, without warranty of any kind, express or implied. This is
|
| not legal advice.
|
| - **Your compliance is yours.** Downstream users must satisfy each upstream
|
| license themselves — in particular **CC-BY-SA-4.0 attribution and share-alike**
|
| for derivatives of this dataset, and attribution to the upstream sources and to
|
| SpeakLeash.
|
| - **Notice-and-takedown.** Any source or rightsholder raising a substantiated
|
| objection can have material removed: contact **k.wikiel@gmail.com**; it is dropped from
|
| the next version and recorded in the CHANGELOG. Removal is retroactive
|
| going-forward (prior immutable snapshots/commits may persist).
|
|
|
| ## License & attribution
|
| Released under **CC-BY-SA-4.0** (copyleft inherited from CC-BY-SA sources such as
|
| Wikipedia/Wikisource/Wolne Lektury). Attribution due to each upstream (see datasheets)
|
| and to **SpeakLeash** as the intermediate aggregator. Retroactive-removal policy: a
|
| source that raises an objection is dropped from subsequent versions, recorded in the
|
| CHANGELOG.
|
|
|
| ## Reproduce
