Synchronous Tree Unification Grammar
نویسنده
چکیده
This paper presents a novel grammar formalism, Synchronous Tree Unification Grammar (STUG), that borrows ideas from two rather distinct exemplars of tree-based grammar formalisms, namely Synchronous Tree Adjoining Grammar and Tree Unification Grammar. At the same time STUG differs considerably from those in that it allows for a clean separation of syntax and valency. Exploiting this potential in the modelling of natural language grammar has a number of interesting consequences that we will sketch in the course of this paper.

Pied-Piping in Relative Clauses: Syntax and Compositional Semantics Based on Synchronous Tree Adjoining Grammar
In relative clauses, the wh relative pronoun can be embedded in a larger phrase, as in a boy [whose brother] Mary hit. In such examples, we say that the larger phrase has pied-piped along with the whword. In this paper, using a similar syntactic analysis for wh pied-piping as in Han (2002) and further developed in Kallmeyer and Scheffler (2004), I propose a compositional semantics for relative ...
متن کاملPied-Piping in Relative Clauses: Syntax and Compositional Semantics using Synchronous Tree Adjoining Grammar
Abstract. In relative clauses, the wh relative pronoun can be embedded in a larger phrase, as in “a boy [whose brother] Mary hit” and “a boy [whose brother’s friend] Mary hit”. In such examples, we say that the larger phrase containing the wh-word has pied-piped along with the wh-word. In this paper, using a similar syntactic analysis for wh pied-piping as in Han (2002) and further developed in...
متن کاملMapping Scrambled Korean Senteces into English Using Synchronous TAGs
Synchronous Tree Adjoining Grammars can be used for Machine Translation. However, translating a free order language such as Korean to English is complicated. I present a mechanism to translate scrambled Korean sentences into English by combining the concepts of Multi-Component TAGs (MC-TAGs) and Synchronous TAGs (STAGs). 1 M o t i v a t i o n Tree Adjoining Grammars (TAGs) were first developed ...
متن کاملIntegrating a Unification-Based Semantics in a Large Scale Lexicalised Tree Adjoining Grammar for French
In contrast to LFG and HPSG, there is to date no large scale Tree Adjoining Grammar (TAG) equiped with a compositional semantics. In this paper, we report on the integration of a unification-based semantics into a Feature-Based Lexicalised TAG for French consisting of around 6 000 trees. We focus on verb semantics and show how factorisation can be used to support a compact and principled encodi...
متن کاملFeature Unification in TAG Derivation Trees
The derivation trees of a tree adjoining grammar provide a first insight into the sentence semantics, and are thus prime targets for generation systems. We define a formalism, feature-based regular tree grammars, and a translation from feature based tree adjoining grammars into this new formalism. The translation preserves the derivation structures of the original grammar, and accounts for feat...
