The rapid proliferation of AI-generated text online is profoundly reshaping
the information landscape. Among various types of AI-generated text,
AI-generated news presents a significant threat as it can be a prominent source
of misinformation online. While several recent efforts have focused on
detecting AI-generated text in general, these methods require enhanced
reliability, given concerns about their vulnerability to simple adversarial
attacks. Furthermore, due to the eccentricities of news writing, applying these
detection methods for AI-generated news can produce false positives,
potentially damaging the reputation of news organizations. To address these
challenges, we leverage the expertise of an interdisciplinary team to develop a
framework, J-Guard, capable of steering existing supervised AI text detectors
for detecting AI-generated news while boosting adversarial robustness. By
incorporating stylistic cues inspired by the unique journalistic attributes,
J-Guard effectively distinguishes between real-world journalism and
AI-generated news articles. Our experiments on news articles generated by a
vast array of AI models, including ChatGPT (GPT3.5), demonstrate the
effectiveness of J-Guard in enhancing detection capabilities while maintaining
an average performance decrease of as low as 7% when faced with adversarial
attacks.
