Polish Sejm committee transcripts — full API coverage (terms 9 and 10)

Official committee transcripts ("pełny zapis przebiegu posiedzenia") from the Sejm of the Republic of Poland, parsed into individually attributed speaker turns.

Scope

• —Committees: all standing committees with zapis PDFs in the Sejm API.
• —Terms: 9 (2019-11-14 → 2023-11-09) and 10 (2023-11-14 → 2026-09-17).
• —Provider and primary source: Kancelaria Sejmu RP, https://api.sejm.gov.pl/ (/sejm/term{n}/committees/{code}/sittings/{num}/pdf).
• —Each row is one speaker turn: term, committee_code, committee_name, sitting_num, date, turn_idx, speaker, text, content_sha1, source_url.

Exact counts are in artifacts/audit.json (rows, characters, sittings, committees, dedup statistics, speaker-role distribution).

Method

• —PDFs extracted with pdftotext -layout; speaker turns reconstructed from role-anchored speaker labels (Poseł/Przewodniczący/Sekretarz stanu/Legislator/ Głos z sali/…). Speech body dehyphenated; page furniture removed.
• —Joint sittings of two or more committees appear in each committee's sittings list; identical content (per-sitting sha1) is kept once (rows_joint_sitting_dedup_dropped in the audit).
• —Parser validated against the earlier ASW-only pilot: recovers ~99% of the pilot's audited corrected character count, with per-turn attribution.
• —Obvious emails, checksum-valid PESEL/NIP/REGON numbers, labelled phone numbers and IBANs are redacted; this is not a guarantee of zero personal data.
