... for Czech, among others. Dependency grammars represent the structure of the sentences by positing binary dependency relations between words. For instance, Figure 1 Figure 1: Dependency Relations ... Parser Statistical dependency parsers first compute the probabilities of the unit-to-unit dependencies, and then find the most probable dependency tree T ∗ among the set of possible depen...

... results. This simple example shows how to use the subtree information on the target side. 3 Dependency parsing For dependency parsing, there are two main types of parsing models (Nivre and McDonald, ... verify the possible dependency relations among source words. In our approach, we also use the same source subtree features described in Chen et al. (2009). So the possible dependency r...

... Methods Japanese dependency parsing for written language is based on the following principles. Our method re- laxes the first principle to allow self-dependent seg- ments (c.f. Section 2.3). 1. Dependency ... using the above features. 3. Determine the actual dependency by interpret- ing the labels. 4. Shorten the sentence by deleting segments for which the dependency is already determi...

The Japanese dependency structure is usually represented ... recent availability of larger-scale corpora an- notated with dependency information has thus re- sulted in more work on statistical dependency analysis technologies that use machin...

Duchier (1999) formulated a constraint-based ax- iomatization of dependency ... modular de- composition of immediate dependency and linear precedence. Our approach distinguishes two orthogonal yet mutu- ally constraining structures: a syntactic dependency tree a...
