This is a copy of the Multi-News dataset, except the input source documents of its test split have been replaced by a sparse retriever. The retrieval pipeline used:

• query: The summary field of each example
• corpus: The union of all documents in the train, validation and test splits
• retriever: BM25 via PyTerrier with default settings
• top-k strategy: "max", i.e. the number of documents retrieved, k, is set as the maximum number of documents seen across examples in this dataset, in this case k==10

Retrieval results on the train set:

Recall@100	Rprec	Precision@k	Recall@k
0.8793	0.7460	0.2213	0.8264

Retrieval results on the validation set:

Recall@100	Rprec	Precision@k	Recall@k
0.8748	0.7453	0.2173	0.8232

Retrieval results on the test set:

Recall@100	Rprec	Precision@k	Recall@k
0.8775	0.7480	0.2187	0.8250
