Researchers have developed a novel framework for analyzing oppositional narratives, which distinguishes critical speech from coordinated conspiracy theories. This approach utilizes a BERT encoder to extract an entity-interaction graph, which is then classified using a Heterogeneous Graph Transformer. The system achieves state-of-the-art performance on the PAN Oppositional Narratives benchmark with significantly fewer parameters than previous models, while also providing interpretability through counterfactual inference to identify key entities driving discourse.
