Polyglot Semantic Role Labeling
Table 4: Semantic F1 scores on the English test set for each language pair.

English SRL consistently benefits from polyglot training, with an increase of 0.25–0.7 absolute F1 points, depending on the language. Surprisingly, Czech provides the smallest improvement, despite the large amount of data added; the absence of crosslingual transfer in both directions for the English-Czech case, breaking the pattern seen in other languages, could therefore be due to differences in annotation rather than questions of dataset size.
