This repo contains the annotated datasets and expriments implementation introduced in our resource paper in SIGIR2022 Multi-CPR: A Multi Domain Chinese Dataset for Passage Retrieval. [Paper].

Multi-CPR is a multi-domain Chinese dataset for passage retrieval. The dataset is collected from three different domains, including E-commerce, Entertainment video and Medical. Each dataset contains millions of passages and a certain amount of human annotated query-passage related pairs.
Examples of annotated query-passage related pairs in three different domains:
| Domain | Query | Passage |
|---|---|---|
| E-commerce | 尼康z62 (Nikon z62) | Nikon/尼康二代全画幅微单机身Z62 Z72 24-70mm套机 (Nikon/Nikon II, full-frame micro-single camera, body Z62 Z72 24-70mm set) |
| Entertainment video | 海神妈祖 (Ma-tsu, Goddess of the Sea) | 海上女神妈祖 (Ma-tsu, Goddess of the Sea) |
| Medical | 大人能把手放在睡觉婴儿胸口吗 (Can adults put their hands on the chest of a sleeping baby?) |
大人不能把手放在睡觉婴儿胸口，对孩子呼吸不好，要注意 (Adults should not put their hands on the chest of a sleeping baby as this is not good for the baby's breathing.) |
Datasets of each domain share a uniform format, more details can be found in our paper:
- qid: A unique id for each query that is used in evaluation
- pid: A unique id for each passaage that is used in evaluation
| File name | number of record | format |
|---|---|---|
| corpus.tsv | 1002822 | pid, passage content |
| train.query.txt | 100000 | qid, query content |
| dev.query.txt | 1000 | qid, query content |
| qrels.train.tsv | 100000 | qid, '0', pid, '1' |
| qrels.dev.tsv | 1000 | qid, '0', pid, '1' |
The retrieval and rerank folders contain how to train a BERT-base dense passage retrieval and reranking model based on Multi-CPR dataset. This code is based on the previous work tevatron and reranker produced by luyug. Many thanks to luyug.

We have uploaded some checkpoints finetuned with Multi-CPR to ModelScope Model hub. It should be noted that the open-source models on ModelScope are fine-tuned based on the ROM or CoROM model rather than the original BERT model. ROM is a pre-trained language model specially designed for dense passage retrieval task. More details about the ROM model, please refer to paper ROM

基于Multi-CPR数据集训练的预训练语言模型文本表示(召回)模型、语义相关性(精排)模型已逐步通过ModelScope平台开源，欢迎大家下载体验。在ModelScope上开源的模型都是基于ROM或者CoROM模型为底座训练的而不是原始的BERT模型，ROM是一个专门针对文本召回任务设计的预训练语言模型，更多关于ROM模型细节可以参考论文ROM
