+# ParlIR
+
+European Parliament written questions (terms 8–10, 2014–2026) paired with their official Commission/Council
+answers, released as an IR test collection. Code and full documentation:
+https://github.com/NaiveNeuron/ParlIR-ecir-2027 (private until the authors release it).
+
+## Tasks
+
+All tasks have qrels files `qrels/<task>_<split>.tsv` (splits `train`, `dev`, `test`).
+
+- **AnswerRet** (`answer`, config `qrels-answer`): retrieve the official answer to a question from the full answer
+  corpus; binary known-item qrels; primary metric MRR@10.
+- **Lenient AnswerRet** (`answerlenient`): the official answer (rel 2) plus typed equivalent answers (rel 1):
+  `twin_question`, `duplicate_answer`, `near_duplicate_answer` (listed in `equivalents.jsonl`).
+- **CiteRet** (`cite`, config `qrels-cite`; canonical citation task): retrieve earlier answers that the official
+  answer explicitly cross-references; eligible = answers published before the official reply's date (drafting
+  time); metric: known-citation recall (R@10, R@100). `citehc` is the explicit-referral subset.
+- **Pre-submission variant** (`precedent`, `precedenthc`): same citation edges, eligible = answers published before
+  the question date.
+
+## Files
+
+All files of a release live under `<version>/` (this card: `v1.0/`); the git tag `v1.0` freezes them. Runs and
+audit records are under `v1.0/experiments/{runs,audit}/`.
+
+- `corpus.jsonl`: `_id` (`<QID>-ASW`), `text` (masked, canonical), `raw_text` (header-stripped, unmasked),
+  `date`, `institution`, `answers` (question ids), `header`, `source_url`.
+- `queries.jsonl`: `_id`, `subject`, `text` (masked subject + body), `raw_text`, `date`, `source_url`, `type`
+  (E/P), `term`, `addressee`, `author`, `orig_lang`, `orig_lang_src` (`csv`/`detail`), `answer`, `header`, `split`
+  (train/dev/test/null), `joint_size`.
+- `queries_xling.jsonl`: official non-English versions of questions: `_id`, `lang`, `text` (masked), `raw_text`.
+- `equivalents.jsonl`: `qid`, `equivalent_answers` (list of `{doc, type}`).
+- `precedent_meta.jsonl`: per query, citation edges (`cited`, `answer`, provenance `via` ⊆ {`hyperlink`, `url`,
+  `text`}, `referral` flag), with the eligible answers under the pre-submission and drafting cutoffs.
+- `qrels/<task>_<split>.tsv` for `answer`, `answerlenient`, `cite`, `citehc`, `precedent`, `precedenthc`: TREC
+  format `qid 0 docid rel` (whitespace-separated, no header).
+- `build_manifest.json`: counts and sha256 checksums.
+- LLM pooled-audit pools (sensitivity analysis only; reproducible from the sample seed and the runs).
+
+**Masking.** Headers are removed structurally; every question/answer identifier (including URL-embedded ids, hyphen
+variants, ids glued to a language code, and typo forms) is replaced by `[REF]`; term-8 PE-number footers and
+co-signatory/supporter lines are removed. The validator checks for identifiers independently of the masker.
+
+Splits are temporal (train 2014–2021, dev 2022–2023, test 2024–2026); 2015 questions are dated from their XML
+header.
+
+**Counts (v1.0).** Corpus 76,536 answers (Commission 70,397, VP/HR 4,181, Council 1,892, unknown 66); 78,314
+queries = train 59,612, dev 7,735, test 10,962, plus 5 unsplit; `queries_xling.jsonl` 7,683 texts in 22 languages;
+equivalent answers for 1,396 queries (twin_question 419, duplicate_answer 852, near_duplicate_answer 296).
+Qrels (queries / pairs):
+
+| Task | train | dev | test |
+|---|---|---|---|
+| `answer` | 59,612 / 59,612 | 7,735 / 7,735 | 10,962 / 10,962 |
+| `answerlenient` | 59,612 / 70,463 | 7,735 / 7,854 | 10,962 / 11,239 |
+| `cite` | 3,767 / 5,592 | 299 / 441 | 396 / 634 |
+| `citehc` | 2,991 / 4,199 | 186 / 245 | 256 / 352 |
+| `precedent` | 2,302 / 3,393 | 252 / 364 | 301 / 481 |
+| `precedenthc` | 1,788 / 2,462 | 159 / 208 | 192 / 269 |
+
+CiteRet test (396 queries) is a small-sample secondary task; report confidence intervals.
