This is a transformers model trained on the U.S. Comparative Agendas Project (CAP) dataset, annotated with a top-level taxonomy covering 20 policy areas, as well as an "Others" category for non-policy-related text. The model is designed to identify policy and non-policy issues in political discourse.
This model was trained specifically for additional analyses presented in this [paper](https://doi.org/10.1038/s41562-025-02136-2).
## Model performance
