This paper introduces a parser system for the meta grammar formalism of Extensible Dependency Grammar (XDG). XDG is a generalisation of Topological Dependency Grammar (TDG) (Duchier and Debusmann, 2001). The XDG parser system comprises a constraintbased parser for all possible instances of XDG, a statically typed grammar input language, and a flexible backend for handling parser output. A power...

Parsing unrestricted text is useful for many language technology applications but requires parsing methods that are both robust and efficient. MaltParser is a language-independent system for data-driven dependency parsing that can be used to induce a parser for a new language from a treebank sample in a simple yet flexible manner. Experimental evaluation confirms that MaltParser can achieve rob...

Dependency Grammar has been used by linguists as the basis of the syntactic components of their grammar formalisms. It has also been used in natural langauge parsing. In China, attempts have been made to use this grammar formalism to parse Chinese sentences using corpus-based techniques. This paper reviews the properties of Dependency Grammar as embodied in four axioms for the well-formedness c...

Recently, dependency grammar has gained renewed attention as empirical methods in parsing have emphasized the importance of relations between words, which is what dependency grammars model explicitly, but context-free phrase-structure grammars do not. While there has been much work on formalizing dependency grammar and on parsing algorithms for dependency grammars in the past, there is not a co...

The overall goal of our work is to build a dependency grammar-based human sentence processor for Hindi. As a first step towards this end, in this paper we present a dependency grammar that is motivated by psycholinguistic concerns. We describe the components of the grammar that have been automatically induced using a Hindi dependency treebank. We relate some aspects of the grammar to relevant i...

Implementing dependency grammar as a set of defeasible declarative rules has fundamental advantages such as expressiveness, automatic disambiguation, and robustness. Although an implementation and a successful large-scale grammar of German are available, so far the construction of constraint dependency grammars has not been described at length. We report on techniques that were used to write th...
