Determining Relative Argument Specificity and Stancefor Complex Argumentative Structures
Table 6: Accuracy for relative stance at distance 1-4.

As expected, performance degrades for all models as the distance between the pair of claims increases. We find that at distance d=4 Fine-tuned BERT model that incorporates path information in a simple manner performs similarly to the model without path information. The hierarchical model, however, performs significantly better, which further justifies our choice to treat the argument path context as a hierarchical rather than a flat representation.
