This is a copy of the MS^2 dataset, except the input source documents of the train, validation, and test splits have been replaced by a dense retriever.

• 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: facebook/contriever-msmarco via PyTerrier with default settings
• top-k strategy: "oracle", i.e. the number of documents retrieved, k, is set as the original number of input documents for each example

Retrieval results on the validation set:

Recall@100	Rprec	Precision@k	Recall@k
0.4764	0.2395	0.2395	0.2395

Retrieval results on the validation set:

Recall@100	Rprec	Precision@k	Recall@k
0.4364	0.2125	0.2125	0.2125

Retrieval results on the test set:

Recall@100	Rprec	Precision@k	Recall@k
0.4481	0.2224	0.2224	0.2224
