Since WH dependencies also tend to distort the surface subcategorization properties ... the WH operator, and train a classifier to trace down- ward from there, eventually predicting the location of the gap. At each node we encounter, the classi- fier chooses e...

... (84.36% in test). There- fore, we decided to adopt this as a basis in order to get an automatic clause splitting tool for Basque. But as it is known, machine learning techniques cannot be applied ... for each token, we stored whether it was followed by a comma or not. That is, for each word (token), it was stored whether a comma was placed next to it or not. Therefore, each to...
