RETECO curated sample data
5 TEMPO examples + 4 RECOR conversations, supporting passages, qrels, README, and a provenance manifest.
Track 01 sample
TEMPO temporal retrieval
The curated subset contains five queries from Bitcoin, Economics, Genealogy, History, and History of Science and Mathematics, plus all 26 distinct gold passages they reference.
id · 122291_22Why was there a jump in the number of transactions per block—from roughly 2,000 to 3,000—in April–May 2023?
The query requires evidence explaining a time-localized change rather than documents that merely mention Bitcoin transactions or the year 2023.
Track 02 sample
RECOR conversational retrieval
The subset contains four complete conversations from Law, Drones, Biology, and Earth Science: 13 target turns, 15 distinct supporting passages, and 32 positive turn-document judgments.
id · ex_111149In copyright law, how is extending a term different from bringing a work back under copyright after it entered the public domain?
Wait, did any works actually get their copyright back after they had already gone public domain?
Did those older movies ever get their rights back, or were they just out for good?
Important scope
A format demonstration—not a new split.
- Every record is copied from an official public release; no labels, negatives, questions, or answers were synthesized for this package.
- The selection is intentionally diverse and inspectable, not statistically representative or domain-balanced.
- The included documents are only the positive evidence subset. Baselines must run against the corresponding full corpus.
- This package is not the hidden SemEval-2027 test set.
