ReCO: A Large Scale Chinese Reading Comprehension Dataset on Opinion

Data

Dataset is available at https://drive.google.com/drive/folders/1rOAoKcLhMhge9uVQFM2_D1EU0AjnpWFa?usp=sharing

download the data and put the json files to the data/ReCO directory

Stats

Train	Dev	Test-a	Test-b
250,000	30,000	10,000	10,000

Requirenments

transformers
torch>=1.3.0
tqdm
joblib
apex(for mixed-precision training)

Train and Test

For BiDAF and other types of model, you can go to the BiDAF folder and run. But the result is somewhat low _

Pre-training methods finetuning:

For single node training:
python3 train.py --model_type=bert-base-chinese
for multiple nodes distributed training:
python3 -m torch.distributed.launch --nproc_per_node=8 train.py --model_type=bert-base-chinese

If you want to use the original doc as the context, you can set the clean(one['passage']) in prepare_data.py line 29 to clean(one['doc']).
