资源简介:
This is a copy of the [MS^2](https://huggingface.co/datasets/allenai/mslr2022) dataset, except the input source documents of the `train`, `validation`, and `test` splits have been replaced by a __dense__ retriever.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`](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 `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 |

本数据集为[MS^2](https://huggingface.co/datasets/allenai/mslr2022)数据集的副本,仅将其`train`(训练集)、`validation`(验证集)与`test`(测试集)划分的输入源文档替换为**稠密检索器(dense retriever)**所获取的文档。 - **查询(query)**:每个示例的`background`(背景)字段 - **语料库(corpus)**:`train`(训练集)、`validation`(验证集)与`test`(测试集)划分中全部文档的并集。单篇文档由`title`(标题)与`abstract`(摘要)拼接而成。 - **检索器(retriever)**:基于[PyTerrier](https://pyterrier.readthedocs.io/en/latest/)框架、采用默认配置的[`facebook/contriever-msmarco`](https://huggingface.co/facebook/contriever-msmarco)检索模型 - **Top-K检索策略(top-k strategy)**:采用**神谕式(oracle)**策略,即检索返回的文档数`k`被设置为每个示例的原始输入文档数量。 ### 验证集检索结果 | 召回率@100(Recall@100) | R准确率(R-precision) | 精确率@k(Precision@k) | 召回率@k(Recall@k) | | ----------- | ----------- | ----------- | ----------- | | 0.4764 | 0.2395 | 0.2395 | 0.2395 | ### 验证集检索结果 | 召回率@100(Recall@100) | R准确率(R-precision) | 精确率@k(Precision@k) | 召回率@k(Recall@k) | | ----------- | ----------- | ----------- | ----------- | | 0.4364 | 0.2125 | 0.2125 | 0.2125 | ### 测试集检索结果 | 召回率@100(Recall@100) | R准确率(R-precision) | 精确率@k(Precision@k) | 召回率@k(Recall@k) | | ----------- | ----------- | ----------- | ----------- | | 0.4481 | 0.2224 | 0.2224 | 0.2224 |
