... practical solution for many NLP problems. This paper presents new, concise ILP formu- lations for projective and non-projective depen- dency parsing. We believe that our formula- tions can pave the way for ... respect to exact inference for the same set of features. Bold indicates the best result for a language. As for overall performance, both the exact and relaxed full model out...

... defin- ing the feature vector is needed for the search in Section 3: the contribution of the ’negative’ fea- tures for c = 0 is only computed when Eq. 1 is evaluated for the highest scoring final hypothesis in ... In the feature vector f (c, S, T ), each feature f i occurs potentially twice, once for each class c ∈ {0, 1}. For the feature vector f(c = 1, S, T ), all the fea- ture valu...

Let Q be a set of ... statistical formalisms (limited to isomorphic trees), synchronous TSG allows local distortion of the tree topol- ogy.

For all sets, parsing ... morphosyntactic information selected in tandem with morphological segmentation is more informative for syntactic analysis than segmenta- tion alone. We also observe decreasing str...
