A Parser System for Extensible Dependency Grammar

نویسنده

  • Ralph Debusmann
چکیده

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 powerful graphical user interface provides for easy accessibility of all the functionality of the system. In the future, we will use the XDG parser system to accomodate new dependency grammar formalisms such as Semantic Topological Dependency Grammar (STDG), and to experiment with other interesting XDG instances.

Feature Engineering in Persian Dependency Parser

Dependency parser is one of the most important fundamental tools in the natural language processing, which extracts structure of sentences and determines the relations between words based on the dependency grammar. The dependency parser is proper for free order languages, such as Persian. In this paper, data-driven dependency parser has been developed with the help of phrase-structure parser fo...

A Relational Syntax-Semantics Interface Based on Dependency Grammar

We propose a syntax-semantics interface that realises the mapping between syntax and semantics as a relation and does not make functionality assumptions in either direction. This interface is stated in terms of Extensible Dependency Grammar (XDG), a grammar formalism we newly specify. XDG’s constraint-based parser supports the concurrent flow of information between any two levels of linguistic ...

BANK OF ENGLISH AND BEYOND Hand-crafted parsers for functional annotation

The 200 million word corpus of the Bank of English was annotated morphologically and syntactically using the English Constraint Grammar analyser, a rulebased shallow parser developed at the Research Unit for Computational Linguistics, University of Helsinki. We discuss the annotation system and methods used in the corpus work, as well as the theoretical assumptions of the Constraint Grammar syn...

OSU_CHGCG at SemEval-2016 Task 9 : Chinese Semantic Dependency Parsing with Generalized Categorial Grammar

This paper introduces our Chinese semantic dependency parsing system for Task 9 of SemEval 2016. Our system has two components: a parser trained using the Berkeley Grammar Trainer on the Penn Chinese Treebank reannotated in a Generalized Categorial Grammar, and a multinomial logistic regression classifier. We first parse the data with the automatic parser to obtain predicate-argument dependenci...

Modular Grammar Design with Typed Parametric Principles

This paper introduces a type system for Extensible Dependency Grammar (xdg) (Debusmann et al., 2004), a new, modular grammar formalism based on dependency grammar. As xdg is based on graph description, our emphasis is on capturing the notion of multigraph, a tuple of arbitrary many graphs sharing the same set of nodes. An xdg grammar consists of the stipulation of an extensible set of parametri...
