sentence-transformers/NanoFEVER-bm25

这个数据集是NanoBEIR FEVER with BM25 rankings，是FEVER数据集的一个子集，FEVER本身是BEIR信息检索基准的一个更高效的子集。该数据集在relevance子集中新增了一个bm25-ranked-ids列，包含了对每个查询语料库中的每个段落通过BM25算法的排名。这个数据集被用于评估Sentence Transformers中的CrossEncoder模型在NanoBEIR上的表现，通过对BM25的 top *k* 结果进行重排。

This dataset is NanoBEIR FEVER with BM25 rankings, which is a subset of the FEVER dataset from the Benchmark for Information Retrieval (BEIR). FEVER was created as a subset of the rather large BEIR, designed to be more efficient to run. This dataset adds a `bm25-ranked-ids` column to the `relevance` subset, which contains a ranking of every single passage in the corpus to the query. This dataset is used in Sentence Transformers for evaluating CrossEncoder (i.e. reranker) models on NanoBEIR by reranking the top *k* results from BM25.
