# Polish Parliamentary Corpus (Sejm and Senate, 1919-2025) - official parliamentary materials The Sejm and Senate part of IPI PAN's Polish Parliamentary Corpus (PPC), rebuilt from its speaker-labelled TEI dump: plenary and committee sittings **limited to statements by official speakers** (MPs and senators, members of the government, heads of constitutional organs, Sejm and Senate staff; see "Speaker allowlist"), and Sejm interpellations, questions and the government's replies kept whole: **329,863 records / 1,504,127,614 `cl100k_base` tokens / 4,098,061,466 characters** (43,728 sittings, 286,135 interpellation records), 1919-2025. The Sejm from term 9 (2019-) is not here: `sejm_api`, `sejm_committee_transcripts` and `sejm_interpellations` cover it. ## Origin and license - Origin: Polish Parliamentary Corpus, Institute of Computer Science, Polish Academy of Sciences (IPI PAN), . Route: the per-term TEI dump of 2025-05-21, downloaded directly from IPI PAN's server on 2026-10-07 (`https://kdp.ipipan.waw.pl/static/ppcdump-tei/-tei.zip`, 28 zips, 26,409,547,075 bytes) and pinned by size and SHA-256 in `src/fetch_parliamentary.py`. The builder requests no other host: nothing was fetched from the Chancelleries' own sites. The texts are the stenographic reports, committee transcripts and interpellations published by the Chancelleries of the Sejm and the Senate (each TEI header names the publisher). Each record's `ppc_path` in `parliamentary.attribution.jsonl` pins its document in the dump. - Credit: IPI PAN. The TEI markup that this source is cut and filtered by - speaker turns, speaker ids, roles and dates - is IPI PAN's. A speaker label in a record or in the attribution sidecar may be the Chancellery's own printed text as IPI PAN carried it over (printed typos such as "Poeł" survive), and the dump does not say which labels IPI PAN normalised: the labels are credited as IPI PAN's transcription of the Chancelleries' text.

IPI PAN's PPC page says "The parliamentary data is public domain." (and that the corpus annotations are CC BY). We read the page on 2026-10-18; its footer says it was last edited on 2026-10-02, and a copy is archived in polish-dynaword-v2 (`evidence/ppc_page_2026-10-18.html`, pull request 120). We record the sentence as provenance, not as our legal basis: the basis is art. 4(2), our assessment, and it does not rest on that page. The page does not date the sentence's first publication. Asked whether the sentence also covers IPI PAN's database right (art. 6 of the Act of 27 July 2001 on the protection of databases), IPI PAN confirmed by e-mail on 2026-10-19 that it covers its right as producer of the database, and agreed to the resource's inclusion in this collection under the collection's CC BY-SA 4.0 tag. That is IPI PAN's consent about its own rights and about the collection-level tag; it does not give the texts a licence and does not speak for the Sejm or the Senate. The reply is archived in polish-dynaword-v2 (`evidence/ipipan_reply_2026-10-19.md`, pull request 122). Asked for its basis, IPI PAN answered (e-mail, 2026-10-07) that it is public information made available by statute (the Open Data Act and the Access to Public Information Act), with no agreement with the Chancelleries. Asked whether the documents it received from the Sejm Library (Biblioteka Sejmowa) came with conditions or limits on further use, IPI PAN answered (e-mail, 2026-10-08) that they were handed over without further restrictions. Record license: `public-domain (official documents)`. No Creative Commons grant is claimed for the text. The art. 4(2) basis is our assessment and a statement of Polish law only; the status may differ in other jurisdictions. It covers the interpellations, questions and replies and, in sittings, the turns the allowlist keeps (MPs and senators, members of the government, heads of constitutional organs and Sejm and Senate staff). We do not treat statements of guests at sittings (people from outside Parliament and the administration) as official documents, so they are left out (polish-dynaword-v2#54). The statement does not extend to third-party texts read out or quoted inside a kept turn (for example citizens' letters), which are kept unfiltered as part of the record, and personal data is a separate matter (see "PII" under "Collection and normalization"). ## What the texts are - **Genre**: stenographic reports of plenary sittings; transcripts and bulletins of committee sittings; interpellations and questions ("zapytania") of MPs with the government's replies. - **Register**: parliamentary Polish as recorded and edited by the stenographers - speeches, debate with interruptions, chair announcements, read-out documents - and, in the interpellations, formal letters to and from ministers. The texts of 1919-1989 were digitised from the printed reports (the dump does not say how; each header names an `.odt` original): samples read clean, interwar spelling is kept ("zależnem"), and some speaker labels carry typos ("Poeł", "Marszalek"). Not machine-translated. - **Time span**: | Period | House | Kind | Records | Characters | Dates | |---|---|---|---:|---:|---| | 1919-1939 | Sejm | plenary | 1,021 | 156,362,280 | 1919-02-10 - 1939-09-02 | | 1919-1939 | Senat | plenary | 323 | 43,495,751 | 1922-11-28 - 1939-09-02 | | 1944-1946 | Krajowa Rada Narodowa | plenary | 6 | 1,093,152 | 1944-12-31 - 1946-09-23 | | 1947-1989 | Sejm | plenary | 460 | 111,637,467 | 1947-02-04 - 1989-05-30 | | 1947-1989 | Sejm | committee | 2,432 | 62,298,363 | 1965-09-17 - 1989-05-29 | | 1989-1991 | Sejm | plenary | 79 | 47,102,915 | 1989-07-04 - 1991-10-25 | | 1989-1991 | Senat | plenary | 61 | 18,104,530 | 1989-07-04 - 1991-10-24 | | 1991-2019 | Sejm | plenary | 2,093 | 927,132,601 | 1991-11-25 - 2019-10-16 | | 1991-2019 | Sejm | committee | 31,360 | 1,177,647,251 | 1993-05-23 - 2019-10-16 (one sitting dated 1988, see caveats) | | 1997-2019 | Sejm | interpellations | 286,135 | 1,063,165,695 | terms 3-7 undated (1997-10-20 - 2015-11-11 by term); term 8 2015-11-17 - 2019-04-04 | | 1991-2025 | Senat | plenary | 1,375 | 346,591,211 | 1991-11-26 - 2025-04-24 | | 2015-2025 | Senat | committee | 4,518 | 143,430,250 | 2015-11-13 - 2025-04-24 | Interpellation records: 110,162 interpellations (251,313,419 characters), 108,433 replies to them (610,085,424), 34,997 questions (60,724,007) and 32,543 replies to questions (141,042,845). 20,447 distinct speaker labels are kept. ## Collection and normalization Every step lives in `src/fetch_parliamentary.py`; the shard is reproducible from the pinned dump (`--download` fetches it and refuses a zip whose size or SHA-256 differs). - **Scope**: every term of the dump except `2019-2023/sejm/` and `2023-2027/sejm/` (5,940 documents), which the `sejm_*` sources cover; the Senate of 2019-2025 is kept. The Sejm part ends with the sitting of 2019-10-16; `sejm_api` checks that its own material starts after the end of term 8 (`PARLIAMENTARY_SEJM_END` = 2019-11-11 in `src/sejm_api_common.py`). - **Records**: one record per sitting document (a sitting day, as the dump splits it) or per interpellation, question or reply. A sitting's text is its kept utterances (``) joined by newlines, without speaker labels; a dropped turn leaves no marker. The attribution sidecar lists per record the kept speaker labels (`speakers`), `kept_characters` and `dropped_characters`, and the header's `system`, `house`, `type`, `term_no` and `date`. An interpellation's text is its paragraphs; its header names the author (279,628 records carry an `author`; sittings carry none). The dump runs co-authors together in one `` ("Tomasz GarbowskiTadeusz TomaszewskiBogusław Wontor"); `author` keeps the string as given. - **Dates**: `created` is the sitting or letter date. The dump writes 175 sittings over several days as one date string ("1938-11-28 i 29", "1952-07-31 i 08-01"); they get the range "first, last". The 213,652 interpellation records of terms 3-7 carry no date in the dump and get their term's range (e.g. "1997-10-20, 2001-10-18"); the sidecar's `date` keeps the dump's string (empty for those). - **Speaker allowlist** (sittings only, plenary and committee): every speaker in a sitting's header is classified once, by its role followed by a placeholder name ("Jan Maria Kowalski"), against the anchored rules `SPEAKER_RULES` of `src/fetch_sejm_committee_transcripts.py` (the `sejm_committee_transcripts` allowlist) and then `PPC_RULES` in `src/fetch_parliamentary.py`. A turn is kept only if its speaker matches a rule; a speaker no rule recognises is dropped (fail closed). A person's own name that is not a 1-3 token name ("Piotr van der Coghen", "Jan Bury s. Antoniego", "Artur Płokszto z Litwy") is kept only if it is, or starts with, the name of an MP, senator or marshal of the same term zip (the chairs' member check, below; 349 persons kept, 673 dropped). PPC's removal of party tags sometimes leaves a cut tag as one more surname part ("(niez"; 1,850 persons), which is ignored. PPC strips the party tags that the base allowlist keys MPs on, so it matches only 3,804 characters of bare `mp` turns; the PPC rules close that gap. Kept, by rule (characters of utterance text, turns; `parliamentary.speaker-roles.csv` lists every role with its decision): | Rule | Keeps | Characters | Turns | |---|---|---:|---:| | `mp_no_party` | "Poseł/Posłanka NAME", with "Sprawozdawca", "Sekretarz", "Wiceprzewodniczący"; "Sekretarz poseł NAME"; the typo "Poeł" | 1,694,953,227 | 4,477,657 | | `state_secretary` | secretaries and undersecretaries of state in a ministry or the Chancellery of the Prime Minister (base rule) | 325,593,817 | 614,984 | | `senator` | "Senator NAME" (base rule) | 315,926,447 | 883,499 | | `marshal_no_house` | the chamber's own marshal and deputy marshals without "Sejmu"/"Senatu", "Marszałek Senior"; never a voivodeship marshal | 190,540,640 | 2,407,101 | | `mp_committee_chair` | committee chairs who are MPs (base rule) | 158,002,628 | 1,038,553 | | `government_member` | the Prime Minister, deputy PMs, ministers (base rule) | 87,399,387 | 175,562 | | `committee_chair_named` | a committee chair or deputy chair named in the label, only if the name is an MP's, senator's or marshal's of that term (see below) | 46,499,132 | 439,802 | | `government_historic` | "Prezydent Ministrów" (1919-21), "Prezes Rady Ministrów", "Wicepremier", ministers under historic names ("Minister Skarbu", "Minister Wyznań Religijnych i Oświecenia Publicznego", "Minister Przemysłu Chemicznego"), "Kierownik Ministerstwa ...", "Minister - Szef Urzędu Rady Ministrów" | 41,519,929 | 78,012 | | `state_secretary_historic` | secretaries of state of historic ministries and of the Urząd Rady Ministrów (the Prime Minister's office before KPRM) | 36,177,142 | 72,609 | | `constitutional_organ_head` | RPO, RPD, Prezes NIK, NBP, TK, NSA, Pierwszy Prezes SN, KRRiT, KRS, Prokurator Generalny (base rule) | 34,642,977 | 55,742 | | `legislative_petitions_staff` | the Sejm's "Przedstawiciel Biura Legislacyjnego", Senate legislators and experts of the Biuro Legislacyjne, petitions staff of the Senate | 32,427,046 | 97,234 | | `sejm_legislator` | Biuro Legislacyjne legislators (base rule) | 20,914,344 | 73,630 | | `senator_no_party` | "Senator/Senatorka NAME" with "Sekretarz", "Sprawozdawca", "RP" | 10,344,087 | 43,480 | | `stage_direction` | the stenographers' bracketed directions ("(Oklaski)", "(Początek posiedzenia o godz. 10)") | 8,281,651 | 471,173 | | `mp_surname_1919_1939` | "P. Nowicki" in the Sejm of 1919-39 (not before an office) | 6,505,299 | 12,467 | | `sejm_senate_office_head` | heads of the Sejm and Senate offices (base rule) | 5,579,703 | 13,761 | | `sejm_bureau_expert` | BAS and BEOS experts (base rule) | 3,373,664 | 5,918 | | `sejm_senate_marshal` | "Marszałek Sejmu/Senatu" (base rule) | 2,502,494 | 9,317 | | `senator_surname_1919_1939` | "S. Karnicka" in the Senate of 1922-39 | 1,792,371 | 2,567 | | `komentarz_continuation` | an unbracketed stenographer's line continuing a kept speaker in the same turn block | 548,873 | 28,611 | | `sejm_committee_secretary` | "Sekretarz Komisji ... NAME" (base rule) | 543,439 | 8,392 | | `mp` | MP labels with a party tag (base rule) | 3,804 | 13 | Evidence for the PPC rules (also in the code comments and on polish-dynaword-v2#54): "P. X" and "S. X" are announced as MPs and senators in the same texts ("Głos ma poseł Nowicki" before "P. Nowicki", "Głos ma s. Karnicka"); "P." before an office in 1919-39 is "Pan" and is cut before the label is classified (12 persons), and "P." in the Senate (17k characters) stays out. A marshal without "Sejmu"/"Senatu" in a sitting of the Sejm or Senate is that chamber's marshal; labels naming a voivodeship, sejmik or board are excluded. A chair's name, and any name that is not a 1-3 token name, is checked against the MPs, senators and marshals of the same term zip (headers of the dropped 2019-2023 Sejm included). Case, punctuation, soft hyphens and one-letter tokens are ignored, two parts run together are split ("JanuszPalikot"), and a name that starts with a member's counts ("Jan Bury s. Antoniego"). A member's name of 4 tokens or with a particle ("Piotr van der Coghen") is taken only from the header of a plenary sitting. Chairs who are not members, such as a foreign or ministry committee's chair, are dropped (876 persons, 6,691,887 characters). The historic ministry words were taken from the label census of the whole dump (2026-10-07). Dropped, by reason (characters of utterance text): | Reason | Characters | What it is | |---|---:|---| | `speaker:unmatched` | 601,219,281 | a named speaker whose role matches no rule (117,972 persons) | | `speaker:no_role` | 84,057,911 | a name without a role in the header (12,222 persons): MP or guest cannot be told | | `komentarz_colon` | 24,479,841 | a stenographer's line with ": ", i.e. an interjection ("Głos z sali: ...") | | `komentarz_unattributed` | 9,757,058 | an unbracketed stenographer's line with no speaker before it in its turn block | | `speaker:role_only_unmatched` | 9,322,256 | a role without a name that matches no rule (8,525 persons) | | `inline_speaker` | 8,416,268 | text after a speaker line inside a turn whose label is not kept (see caveats) | | `speaker:chair_not_member` | 6,691,887 | a named chair who is not an MP or senator of that term | | `speaker:bad_name` | 3,074,332 | a name that is not 1-3 tokens and not a member's (673 persons: ambassadors, witnesses, "Dr NAME, Uniwersytet ...", foreign MPs "Poseł Artur Płokszto z Litwy") | | `speaker:free_unmatched` | 1,782,824 | a free-text header label that no rule keeps | | `komentarz_continuation_dropped` | 1,548,523 | a stenographer's line continuing a dropped speaker | | `inline_label_line` | 352,435 | the speaker lines inside turns themselves | The allowlist keeps 3,024,072,101 of 3,774,774,717 characters of utterance text (80.1%). The largest dropped roles: the role-less names above (84.06M), bare "Podsekretarz stanu" (27.39M, 65,361 turns) and "Sekretarz stanu" (6.70M) without a ministry - the President's Chancellery uses the same titles, so they cannot be told apart and fail closed -, "Dyrektor" (16.82M), "Wiceminister" (11.80M, 31,147 turns; not in the allowlist), "Prezes" (9.49M), "Wiceprezes NIK" (5.32M), "Sprawozdawca" without "poseł" (4.64M), "Ekspert Komisji" (3.07M), candidates for ambassador (2.91M), representatives of citizens' legislative initiatives (2.35M), the secretaries of state of the President's Chancellery (2.21M) and witnesses of investigative committees (0.91M). Also out: the RCL, ministry departments, heads of agencies other than the constitutional organs, MEPs and the heads of state ("Naczelnik Państwa", "Prezydent RP"). - **Stage directions** (the "komentarz" speaker): a bracketed direction is kept; any other komentarz line is kept only as the continuation of a kept speaker in the same turn block; a line with ": " (an interjection from the floor) is always dropped. - **Speaker lines inside turns**: a `` that ends with ":" and reads as a speaker label switches the speaker until the next speaker change. Such a label is kept only if it matches a rule other than `committee_chair_named` and either names a speaker that the zip's headers keep or puts a title ("ob.", "ks.", "gen.") before the name; this guards against roles that swallow words of a name ("Minister Spraw Zagranicznych Ukrainy Borys Tarasiuk", "Marszałek Polski Józef Piłsudski"). 8,910 such lines: 315 kept by name, 62 by title, 333 refused by the guard, 8,200 matching no rule. - **PII (which scrubber ran)**: the pattern pass `redact()` of `src/fetch_sejm_committee_transcripts.py` - e-mail -> `[ADRES_EMAIL]`, checksum-valid PESEL, NIP, REGON (9 and 14 digits) and IBAN candidates -> `[DANE_NUMERY]`, labelled phone/fax -> `[DANE_KONTAKTOWE]`. Counted in the shipped shard: **11,626 redactions** (6,075 `[DANE_KONTAKTOWE]`, 5,119 `[ADRES_EMAIL]`, 432 `[DANE_NUMERY]`). This is **not** [SlayerLab/NERGAL](https://huggingface.co/SlayerLab/NERGAL): interpellations quote citizens' cases by name, so the shard must be re-run through NERGAL before it is admitted to a release. - **Short documents**: 440 sittings keep no turn and 164 interpellation records have no text; 37 sittings and 583 interpellation records have under 200 characters after the filter and the PII pass. All are dropped; a dropped sitting's turns stay counted under their rule above. - **Encoding**: some records are Windows-1250 text that was read as ISO-8859-2, so "ą" shows as "š" and "ś", "ź" as control characters ("Nawišzujšc" for "Nawiązując"). Such a record is re-decoded when no line of it has a correct "ą", "ś" or "ź"; otherwise only its lines without one are re-decoded, and the stray control characters left next to correct text are mapped to the letters they stand for (`Poto\x88nik` -> "Potočnik"; `_C1_MAP` in the code) or, for a stray 0x98, removed. Kept records repaired (`encoding_repair` in the attribution sidecar): 1,170 re-decoded whole, 1,162 of them Sejm interpellation records of 2007-2011, and 26 repaired by line. A record that cannot be re-decoded fails the build. No control character of U+0080-U+009F is left in the shard. Not detected: 7 lines in 5 records whose other lines are correct and which have no control character ("Dane dotyczšce powiatu lubartowskiego przedstawiajš się następujšco:"; `199701-sjm-ioxxx-01425-01`, `-04177-01`, `-04543-01`, `199701-sjm-zoxxx-02436-01`, `200711-sjm-ioxxx-05532-01`); a rule on "š" alone would also change correct names ("Babiš", "Miloš"). - **Dedup**: records whose text is identical after the encoding repair and the PII pass are kept once: the first in `MANIFEST` order of the term zips, then document order. 18,612 records in 2,143 groups are dropped, all but 7 of them interpellation records: mostly an MP's interpellation or question sent to several ministers, each a record of its own, and a ministry's reply filed under each question it answers (the largest group is one reply under 538 questions). 18,543 of the dropped copies have the same `author` as the kept one. `parliamentary.decisions.jsonl` lists each dropped `id` with the `duplicate_of` id kept in its place. No near-dedup and none against other sources. This source is the reference set that `src/clean_sejm_api_2011_2022.py` deduplicates `sejm_api_2011_2022` against. ## Inclusion argument and caveats What this adds: a century of Polish parliamentary language - interwar, PRL and post-1989 plenary debate, Sejm committee work since 1965, the Senate since 1922, and 1.06B characters of interpellations and ministerial replies. 1.50B tokens. Changes against the shard shipped up to v0.2.5 (SpeakLeash's unlabelled `PPC_corpus`: 324,622 records / 4,492,746,014 characters / 1,646,835,986 tokens, no authors): rebuilt from IPI PAN's labelled dump; guests and other non-official speakers removed from the sittings; 1919-1989 and the Senate of 2019-2025 added; the Sejm from 2019 left to the `sejm_*` sources; interpellation authors recorded; multi-day and undated records dated; misdecoded records repaired; exact copies dropped. Caveats: the allowlist is the conservative reading of art. 4(2), and it reads the printed role label, not the person: a name slot accepts any 1-3 token name, and only committee chairs and longer or unusual names are checked against the members of the term. Officials whose name is damaged (OCR "Teresa MaIczewska", "Krzysztof Michałkiewicz:", the typo "Piotr Van der Koghen") fail that check: about 0.13M characters in a hand review of the 0.39M characters of such names whose role a rule keeps. Officials the rules miss are dropped with the guests: bare "Podsekretarz stanu"/"Sekretarz stanu" (34.09M characters), "Wiceminister" (11.80M) and the role-less names (84.06M, possibly including MPs; a member check like the chairs' could recover those). The speaker-line check inside turns errs towards dropping: on a character-weighted sample of 80 refused lines (seed 20261007), 47 were guests, 28 were prose or headings ending with a colon (the secretary's "Dekrety przedstawione przez Ministerstwo Skarbu:" in 1919, "Koreferat przedstawił poseł X (PZPR)") and 5 were officials whose label the rules miss, so about two fifths of the 8,416,268 characters dropped after such lines is official text lost. A guest's label that does not stand alone in its utterance is not detected and stays inside the previous turn (measured below, for the terms to 1991). Dates: one term-3 committee sitting (`199701-sjm-nusxx-00004-01`) is dated 1988-07-02 in the dump and kept as dated; the 213,652 undated interpellation records carry their term's range, not a day. The dump's Sejm interpellations end on 2019-04-04 and the dump has none of term 9, so Sejm interpellations from April 2019 to the start of `sejm_interpellations` are in no source. Quotations of statutes, prints and citizens' letters are embedded and not filtered (near-dedup against `dziennik_ustaw` and a benchmark-overlap check remain targets). PII treatment is pattern-based (see above). The legal status above is our assessment, not legal advice. Training benefit is an untested hypothesis. Filter check (polish-dynaword-v2#114, 2026-10-19; labels by one labeller, Claude): 480 paragraphs of speaker-attributed text, 40 in each of 12 strata (kept or dropped, times pre-1989 plenary, pre-1989 committee, Sejm plenary and committee since 1989, Senate plenary, Senate committee), drawn at random in proportion to length. All shares are shares of characters, not of speeches. - Kept: 1 of 240 paragraphs was a guest (a cooperative's vice-president quoted inside a minister's turn in PRL committee minutes, behind an embedded "Role Name:" opener). Weighted, that is 0.05% of the kept characters, but the 95% upper limit is 3.5% (about 107M characters): the sample alone does not rule out a larger leak. A scan of the terms to 1991 for kept paragraphs that open with such an embedded label found 3,528 in the pre-1989 committee minutes (1.63M characters, 2.6% of that group's kept characters). Of 70 hand-labelled among the 2,378 whose opener matches no ministry, NIK, MP or Chancellery pattern, 21 were guests: about 0.3M characters (0.2-0.5M), 0.011% of all kept characters. Terms from 1991 were not scanned. - Dropped: of the 714.6M dropped characters with an attributed speaker, 18% (95% interval 12-29%, about 132M characters) are official text that the rules miss, 38% (27-50%) are officials left out by design (agencies, ministry departments, the President's Chancellery, heads of state, MEPs, the RCL) and 44% (32-56%) are guests or others. - Of the official text, the allowlist keeps 95.8% (93.6-97.3%): 97.6% in pre-1989 plenary, 74.1% in pre-1989 committee, 99.1% in Sejm plenary and 93.3% in Sejm committee since 1989, 98.9% in Senate plenary and 96.5% in Senate committee. What it misses: ministers and deputy ministers under titles no rule matches, NIK, prosecutors, NBP and Supreme Court officers, rapporteurs labelled "Sprawozdawca" with no "poseł", and role-less names of MPs (a member check would recover those; 3 of 11 role-less paragraphs in the sample). Of the 13 dropped paragraphs that follow a refused speaker line, 11 were official text: too few to replace the two-fifths estimate above, and higher. - Not established: intervals are wide (40 paragraphs per stratum); the boundary of "left out by design" is ours; the human check of the labels is not done. The sample covers sittings only: interpellations, questions and replies are kept whole, with no speaker filter, so it says nothing about them. No rule was changed because of this check. Details: `artifacts/source_findings.md`, "parliamentary — filter effectiveness". Limitations: records are sitting documents, not turns; the order of kept turns is preserved, and `ppc_path` in `parliamentary.attribution.jsonl` links each record to the TEI document with the full sitting. Figures: `parliamentary.stats.json`.
