Adversarial Training for News Stance Detection: Leveraging Signals from a Multi-Genre Corpus

Proceedings of the EACL Hackashop on News Media Content Analysis and Automated Report Generation

pp. 1-7 (2020)

Abstract: Cross-target generalization constitutes an important issue for news Stance Detection (SD). In this short paper, we investigate adversarial cross-genre SD, where knowledge from annotated user-generated data is leveraged to improve news SD on targets unseen during training. We implement a BERT-based adversarial network and show experimental performance improvements over a set of strong baselines. Given the abundance of user-generated data, which are considerably less expensive to retrieve and annotate than news articles, this constitutes a promising research direction.
