Therefore, we have also included the labeled attachment score restricted to the G set for the parser using the B set (BG), and we see then that the attachment score improves, especially for Model 2. (All differences are significant beyond the .01 level; McNemar's test.) Table 2 shows the dependency accuracy, root accuracy and complete match scores for our best parser (Model 2 with label set B) in comparison with Collins (1997) (Model 3) , Charniak (2000) , and<cite> Yamada and Matsumoto (2003)</cite> .
