| Czech abstract |
Pro mnoho jazyků nemůžeme natrénovat parser, protože nemáme k dispozici žádná ručně anotovaná data. Tento problém můžeme vyřešit použitím paralelního korpusu s angličtinou naparsováním amglické strany a projekcí závislostí do druhého jazyka. |
| English abstract |
For many languages, we are not able to train any supervised parser, because there are
no manually annotated data available. This problem can be solved by using a parallel corpus
with English, parsing the English side, projecting the dependencies through word-alignment
connections, and training a parser on the projected trees. In this paper, we introduce a
simple algorithm using a combination of various word-alignment symmetrizations. We prove
that our method outperforms previous work, even though it uses McDonald's maximum-spanning-tree
parser as it is, without any "unsupervised" modifications.
