Provenance and reproducibility

Official provider: Kancelaria Sejmu RP.
Data route: Sejm API data via contributor snapshot. The text comes from the Hugging Face dataset PiotrSty/sejm-speeches-corpus@v1.0.1, not from the live API; SlayerLab did not re-fetch it from api.sejm.gov.pl.
Immutable source release: PiotrSty/sejm-speeches-corpus@v1.0.1.
Pinned source commit: 124557799608ce4212cf22fa90ca7904618de1b6.
Reviewed DynaWord base commit: 8cc48a3c564ac9edabfbbf012842ad11f70a3e5c.
Rebuild: python src/fetch_sejm_api.py --help, then python3 src/clean_sejm_api.py (trailer cut, below).
Speaker attribution and source URLs are in sejm_api.attribution.jsonl. Each source_url is a day-level listing (https://api.sejm.gov.pl/sejm/term{N}/videos/{date}), not a per-speech URL.
Slayer contribution digest: sha256:38e42a791d68d593f82e1125f2bb94cd8f68212433e71d3e3da90f82d78eaf32.

Temporal novelty and deduplication

The Sejm material of parliamentary ends with term 8 (2019-11-11; its Senate material is not compared: this source is Sejm-only). Every contributed record is dated on or after 2023-01-01, so its date range does not overlap it. Exact duplicate speech texts within the contribution are removed using SHA-1 fingerprints; this is not a claim of global cross-domain near-deduplication.

Trailer cut

The rights audit (slayerlabs/polish-dynaword-v2#57) found that the snapshot appends to 34,980 of the 38,812 fetched speeches a "Przebieg posiedzenia" header of a later statement of the same sitting day, and sometimes that statement's text. src/clean_sejm_api.py cuts every trailer (23,485,670 characters). An appended statement with text becomes a row of its own (2,466 rows), credited to the speaker the header names ("Przebieg posiedzenia Janusz Kowalski: …"), without the office in its label. Its date and term are those of the row it was cut from: the snapshot labels the 11th sitting of term 10 (2024-05-08, 2024-05-09, 2024-05-15) "11. kadencja" in 696 headers. A split row's id hashes its date, term, speaker and text like every other row; its sidecar line carries split_from (the id of the row it was cut from in v0.2.5) and has_events: null, since the snapshot's events flag describes the whole parent row. Rows that fall under the fetch's 200-character minimum after the cut (1,318 cut speeches and 53 split rows) and 8 texts that became exact duplicates are dropped.

Privacy and limitations

The upstream release heuristically redacts email addresses, PESEL identifiers and unambiguous Polish telephone numbers. Public-official names and speech attribution remain. Regex redaction is not a guarantee of zero personal data. Downstream users must review applicable privacy, third-party and source terms.
