This dataset includes extracted hard negatives, along with relevance scores between questions and text spans, and reranker scores. It can be used for training models such as OpenProvence.

This dataset is based on MS MARCO and follows the license of the original MS MARCO dataset.

Available Subsets

Recommended: freq2 — 260,436 train / 1,000 validation / 1,000 test rows. This split applies the MD5-based frequency filter with N=2, removing any row whose passages have already surfaced more than twice. The trimmed validation/test sets are freshly sampled (1k each) so their duplication profile matches the training subset (≈10% duplicate texts). Use this configuration when you want balanced coverage with significantly reduced redundancy and faster training cycles.

default — 492,729 train / 5,000 validation / 5,000 test rows. Full MS MARCO conversion after attaching teacher scores (gte-reranker-modernbert-base, ruri-v3-reranker-310m, bge-reranker-v2-m3, japanese-reranker-*). Intra-row duplication is minimal (<0.01%), so the split keeps the complete breadth of the corpus. Reach for this if you need the original distribution or larger evaluation sets.
