+This repository contains up to 1000 hard negatives from several retrieval systems for the 6,980 queries of the MS MARCO small dev set. This data can be used to evaluate 
+the performance of reranking models for 2nd-stage retrieval given a set of 1000 candidate passages (including the positive ones).
