Researchers have developed a transformer-based model to predict the political ideology of German texts on a continuous left-to-right spectrum. They evaluated 13 transformer models using four distinct corpora, including parliamentary notes, an online decision-making tool, newspaper articles, and tweets from German Bundestag members. DeBERTa-large achieved the highest F1 score on in-domain tasks, while Gemma2-2B performed best on newspaper data. The study indicates that transformer models can accurately gauge political framing, comparable to public opinion polls, and highlights the importance of both model architecture and domain-specific data.
