This is a copy of the MS^2 dataset, except the input source documents of its validation split have been replaced by a sparse retriever. The retrieval pipeline used:

• query: The background field of each example
• corpus: The union of all documents in the train, validation and test splits. A document is the concatenation of the title and abstract.
• retriever: BM25 via PyTerrier with default settings
• top-k strategy: "mean", i.e. the number of documents retrieved, k, is set as the mean number of documents seen across examples in this dataset, in this case k==17

Retrieval results on the train set:

Recall@100	Rprec	Precision@k	Recall@k
0.4333	0.2163	0.2051	0.2197

Retrieval results on the validation set:

Recall@100	Rprec	Precision@k	Recall@k
0.3780	0.1827	0.1815	0.1792

Retrieval results on the test set:

Recall@100	Rprec	Precision@k	Recall@k
0.3928	0.1898	0.1951	0.1820
