Detecting Syntactic Features of Translated Chinese
Table 4: Results for individual subtrees
['Features', 'F (%)']
Now we turn to features of subtrees rooted in specific syntactic categories. Using only NP-headed rules gives us an F-measure of 86.4%. Larger subtrees fare slightly worse, probably indicating data sparsity. However, these results mean that noun phrases alone often provide enough information whether the text is translated.
