A model for predicting a subset of MediaFrames given an argument (has not to be structured in premise/ conclusion or something else). To investigate the generic frame classes, have a look at The Media Frames Corpus: Annotations of Frames Across Issues

Also, this model was fine-tuned on the data provided by this paper. To be precise, we did the following:

To apply these frames to arguments from DDO, we fine-tune a range of classifiers on a comprehensive training dataset of more than 10,000 newspaper articles that discuss immigration, same-sex marriage, and marijuana, containing 146,001 labeled text spans labeled with a single MediaFrame-class per annotator. To apply this dataset to our argumentative domain, we broaden the annotated spans to sentence level (see here). Since an argument can address more than a single frame, we design the argument-frame classification task as a multi-label problem by combining all annotations for a sentence into a frame target set. In addition, to broaden the target frame sets, we create new instances merging two instances by combining their textual representation and unifying their target frame set.
