When using BERT encoder representations, the Chart parser (with its unstructured decoder) and In-Order parser (with its conditioning on a representation of previously-constructed structure) obtain roughly comparable F1 (shown in the first two columns of Table 5), with In-Order better on seven out of nine corpora but often by slight margins.
these aggregate F1 scores decompose along the structure of the tree, and are dominated by the short spans which make up the bulk of any treebank.
