资源简介:
This is a copy of the [Multi-XScience](https://huggingface.co/datasets/multi_x_science_sum) dataset, except the input source documents of the `train`, `validation`, and `test` splits have been replaced by a __dense__ retriever.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__: [`facebook/contriever-msmarco`](https://huggingface.co/facebook/contriever-msmarco) via [PyTerrier](https://pyterrier.readthedocs.io/en/latest/) 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 `train` set: | Recall@100 | Rprec | Precision@k | Recall@k | | ----------- | ----------- | ----------- | ----------- | | 0.5270 | 0.2005 | 0.2005 | 0.2005 | Retrieval results on the `validation` set: | Recall@100 | Rprec | Precision@k | Recall@k | | ----------- | ----------- | ----------- | ----------- | | 0.5310 | 0.2026 | 0.2026 | 0.2026 | Retrieval results on the `test` set: | Recall@100 | Rprec | Precision@k | Recall@k | | ----------- | ----------- | ----------- | ----------- | | 0.5229 | 0.2081 | 0.2081 | 0.2081 |

本数据集为[Multi-XScience](https://huggingface.co/datasets/multi_x_science_sum)数据集的副本,仅将其`train`(训练集划分)、`validation`(验证集划分)与`test`(测试集划分)的输入源文档替换为**稠密检索器(dense retriever)**所获取的内容。所采用的检索流程如下: - **查询(query)**:每个样本的`related_work`(相关工作)字段 - **语料库(corpus)**:`train`、`validation`和`test`划分中所有文档的并集 - **检索器(retriever)**:通过[PyTerrier](https://pyterrier.readthedocs.io/en/latest/)采用默认配置使用[`facebook/contriever-msmarco`](https://huggingface.co/facebook/contriever-msmarco) - **Top-K策略(top-k strategy)**:采用"oracle"(神谕)策略,即检索文档数`k`设置为每个样本原始输入文档的数量 训练集检索结果: | 召回率@100(Recall@100) | R准确率(Rprec) | 精确率@k(Precision@k) | 召回率@k(Recall@k) | | ----------- | ----------- | ----------- | ----------- | | 0.5270 | 0.2005 | 0.2005 | 0.2005 | 验证集检索结果: | 召回率@100(Recall@100) | R准确率(Rprec) | 精确率@k(Precision@k) | 召回率@k(Recall@k) | | ----------- | ----------- | ----------- | ----------- | | 0.5310 | 0.2026 | 0.2026 | 0.2026 | 测试集检索结果: | 召回率@100(Recall@100) | R准确率(Rprec) | 精确率@k(Precision@k) | 召回率@k(Recall@k) | | ----------- | ----------- | ----------- | ----------- | | 0.5229 | 0.2081 | 0.2081 | 0.2081 |

背景与挑战
背景概述
该数据集基于Multi-XScience数据集,使用facebook/contriever-msmarco检索器以'oracle'策略替换了训练、验证和测试分割的输入源文档为密集表示。它在各分割上展示了检索性能,如Recall@100约0.52-0.53,Rprec约0.20-0.21。
