POLITICS

POLITICS, a pretrained model on English news articles of politics, is produced via continued training on RoBERTa, based on a Pretraining Objective Leveraging Inter-article Triplet-loss using Ideological Content and Story.

ALERT: POLITICS is a pre-trained language model that specializes in comprehending news articles and understanding ideological content. However, POLITICS cannot be used out-of-the-box on downstream tasks such as predicting ideological leanings and discerning stances expressed in texts. To perform predictions on downstream tasks, you are advised to fine-tune POLITICS on your own dataset first.

Details of our proposed training objectives (i.e., Ideology-driven Pretraining Objectives) and experimental results of POLITICS can be found in our NAACL-2022 Findings paper and GitHub Repo.

Together with POLITICS, we also release our curated large-scale dataset (i.e., BIGNEWS) for pretraining, consisting of more than 3.6M political news articles. This asset can be requested here.
