This is an official implementation for MDFEND: Multi-domain Fake News Detection which has been accepted by CIKM2021.

The splited dataset (i.e., train, val, test) are in the MDFEND-Weibo21/data folder.

You can have access to the original dataset of Weibo21 only after an "Application to Use Weibo21 for Fake News Detection" has been submitted.

Refer to requirements.txt

You can run pip install -r requirements.txt to deploy the environment quickly.

You can download pretrained model (Roberta) from https://drive.google.com/drive/folders/1y2k22iMG1i1f302NLf-bj7UEe9zwTwLR?usp=sharing and move all the files in the folder into the path MDFEND-Weibo21/pretrained_model/chinese_roberta_wwm_base_ext_pytorch.

After you download the Weibo21 dataset, move the train.pkl, val.pkl and test.pkl into the path MDFEND-Weibo21/data.

You can run this model through:

python main.py --model_name mdfend --batchsize 32 --lr 0.0007
