Table 10: Precision, recall and f-score of different dependency relations on the English development data of the Google universal treebank. The major columns show the dependency labels (“dep.”), frequency (“freq.”), the baseline delexicalized model (“delex”), and our method using the Bible and Europarl (“EU”) as translation data. The rows are sorted by frequency.
['dependency', 'freq', 'Delexicalized prec./rec.', 'Delexicalized f1', 'Bible prec./rec.', 'Bible f1', 'Europarl prec./rec.', 'Europarl f1']
We conclude with some analysis of the accuracy of the method on different dependency types, across the different languages. The improvements in accuracy when moving from the delexicalized model to the Bible or Europarl model apply quite uniformly across all dependency types, with all dependency labels showing an improvement.
