While the directed MST parser (D-MST) is the best performing model across almost all test sets and evaluation measures, it outperforms our best model, U-MST-uf-lep, by a very small margin.
for D-UAS, D-MST outperforms U-MST-uf-lep by up to 1% in 14 out of 20 setups (in 6 setups the difference is up to 0.5%).
