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dataset, except the input source documents of the `train`, `validation`, and `test` splits have been replaced by a __dense__ retriever.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 |
