It finds argumentative spans, assigns them types such as Claim or Premise, and links them with labelled relations such as Support or Attack. Annotated AM data is small and costly to produce.

(2025) proposed parametric faithfulness, which tests whether a Chain-of-Thought (CoT) reflects a model's internal reasoning. The method unlearns individual CoT steps and checks whether the model's No-CoT answer changes. That design attributes every answer change to the removed reasoning step.
