This is a copy of the Multi-XScience dataset, except the input source documents of its test split have been replaced by a sparse retriever. The retrieval pipeline used:
query: The related_work 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: "oracle", i.e. the number of documents retrieved, k, is set as the original number of input documents for each example
