jinaai/jina-embeddings-v5-text-smallover the full corpus to depth 1,000; 100 candidates per query drawn from the rank windows 1–30 (30), 31–100 (30), 101–300 (20), 301–1000 (20), the query's labelled positives excluded.rankis the dense rank;sourceisdensefor a mined row anddatasetfor a negative the source labels itself (those are kept for every query of the split, sampled or not). - Teacher:
jinaai/jina-reranker-v3.5, listwise: a query's positive and all of its candidates are scored together in one context of up to 32,768 tokens.scoreis the raw cosine score, one row per (query, positive) and per (query, candidate); a labelled negative that was also mined is scored once. No filtering is applied to the tables.

Cross-check against the previous layout
This repo previously held the same dataset in BEIR's raw two-repo form (Hyukkyu/beir-msmarco + Hyukkyu/beir-msmarco-qrels; that layout is kept under the git tag legacy-layout). Before replacing it, the build was compared against it: corpus id set identical (8,841,823 documents); qrels rows per split test 7,437 = 7,437, train 532,751 = 532,751.
