... the parsing process is a dependency tree, that exhibits syntactic and semantic information. The dependency structure: The structure combines the traditional view of dependency syntax with ... paper introduces a dependency- based grammar and the associated parser and focusses on the problem of determinism in parsing and recovery from errors. First, it is shown how dependency- b...

... 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...

... In principle, dependency parsing offers good prospects for experimenting with word-to-word-semantic relationships. We present a set of experiments using semantic classes in dependency parsing ... method for training dependency parsers, using word clusters derived from a large unannotated corpus as features. They demonstrate the effective- ness of the approach in a series of depe...
