This model was trained to identify media frames in text at the sentence level. It's based on the Media Frame Corpus [*Card et al. 2015*](https://aclanthology.org/P15-2072.pdf) and extends to online discussion contexts [*Hartmann et al., 2019*](https://arxiv.org/pdf/1904.03969), making it suitable for analyzing both professional journalism and user-generated content.
