- Abstract: Fact verification models have enjoyed a fast advancement in the last two
years with the development of pre-trained language models like BERT and the
release of large scale datasets such as FEVER. However, the challenging problem
of fake news detection has not benefited from the improvement of fact
verification models, which is closely related to fake news detection. In this
paper, we propose a simple yet effective approach to connect the dots between
fact verification and fake news detection. Our approach first employs a text
summarization model pre-trained on news corpora to summarize the long news
article into a short claim. Then we use a fact verification model pre-trained
on the FEVER dataset to detect whether the input news article is real or fake.
Our approach makes use of the recent success of fact verification models and
enables zero-shot fake news detection, alleviating the need of large-scale
training data to train fake news detection models. Experimental results on
FakenewsNet, a benchmark dataset for fake news detection, demonstrate the
effectiveness of our proposed approach.

We study the interplay between machine-(paraphrased) real news, machine-generated fake news, human-written fake news, and human-written real news.
Our experiments reveal an interesting pattern that detectors trained exclusively on human-written articles can indeed perform well at detecting machine-generated fake news, but not vice versa.

Social media has greatly enabled people to participate in online activities at an unprecedented rate.
This unrestricted access also exacerbates the spread of misinformation and fake news online which might cause confusion and chaos unless being detected early for its mitigation.
We jointly leverage the limited amount of clean data along with weak signals from social engagements to train deep neural networks in a meta-learning framework to estimate the quality of different weak instances.
Experiments on realworld datasets demonstrate that the proposed framework outperforms state-of-the-art baselines for early detection of fake news without using any user engagements at prediction time.

We tested the proposed framework on a large collection of news articles published via WeChat official accounts and associated user reports.
