COOLANT

Code for paper "Cross-modal Contrastive Learning for Multimodal Fake News Detection".

Dependency

• python 3.5+
• pytorch 1.0+
• transformers 4.28.0

Dataset

We conduct experiments on two benchmark datasets Twitter and Weibo. In experiments, we keep the same data split scheme as the benchmark. Specifically, for the Twitter dataset, we followed the work of (Chen et al., 2022), and for the Weibo dataset, we followed the work of (Wang et al., 2022).

Training

To train the COOLANT:

python weibo/weibo.py 
python twitter/twitter.py
