Faking Fake News for Real Fake News Detection: Propaganda-loaded Training Data Generation (ACL 2023)

Kung-Hsiang (Steeve) Huang, Kathleen McKeown, Preslav Nakov, Yejin Choi and Heng Ji

Abstract

Despite recent advances in detecting fake news generated by neural models, their results are not readily applicable to effective detection of human-written disinformation. What limits the successful transfer between them is the sizable gap between machine-generated fake news and human-authored ones, including the notable differences in terms of style and underlying intent. With this in mind, we propose a novel framework for generating training examples that are informed by the known styles and strategies of human-authored propaganda.
Specifically, we perform self-critical sequence training guided by natural language inference to ensure the validity of the generated articles, while also incorporating propaganda techniques, such as appeal to authority and loaded language. In particular, we create a new training dataset, PropaNews, with 2,256 examples, which we release for future use. Our experimental results show that fake news detectors trained on PropaNews are better at detecting human-written disinformation by 3.62--7.69% F1 score on two public datasets.

How to use this repo

Please refer to the README within each model directory for specific instructions on how to run them.

Data

The generated data and the test data used in our experiments are included in the data folder. train.jsonl, dev.jsonl, and test.jsonl are our generated data. snopes_test.jsonl and politifact_test.jsonl contain real and fake news from Snopes and PolitiFact.
