3.1 Tree distance evaluation metrics

  1. How is the distance probe evaluated?
    Build the minimum spanning tree of predicted distances and score it by undirected unlabeled attachment score (UUAS) against the gold tree; also compute the Spearman correlation between true and predicted distances per word, averaged over sentences of each length and then over lengths 5–50 (DSpr.).
