Aravind K. Joshi, Laura Kallmeyer and Maribel Romero Flexible Composition in Ltag: Quantifier Scope and Inverse Linking

Flexible Composition in LTAG :

LTAG Semantics of NP-Coordination

A central component of Kallmeyer and Joshi 2003 is the idea that the contribution of a quantifier is separated into a scope and a predicate argument part. Quantified NPs are analyzed as multi-component TAGs, where the scope part of the quantifier introduces the proposition containing the quantifier, and the predicate-argument part introduces the restrictive clause. This paper shows that this as...

Factoring Predicate Argument and Scope Semantics: Underspecified Semantics with LTAG

In this paper we propose a compositional semantics for lexicalized tree-adjoining grammar (LTAG). Tree-local multicomponent derivations allow separation of the semantic contribution of a lexical item into one component contributing to the predicate argument structure and a second component contributing to scope semantics. Based on this idea a syntax-semantics interface is presented where the co...

Quantifier Scope in German: An MCTAG Analysis

Relative quantifier scope in German depends, in contrast to English, very much on word order. The scope possibilities of a quantifier are determined by its surface position, its base position and the type of the quantifier. In this paper we propose a multicomponent analysis for German quantifiers computing the scope of the quantifier, in particular its minimal nuclear scope, depending on the sy...

Scope and Situation Binding in LTAG Using Semantic Unification

This paper sets up a framework for Lexicalized Tree Adjoining Grammar (LTAG) semantics that brings together ideas from different recent approaches addressing some shortcomings of LTAG semantics based on the derivation tree. The approach assigns underspecified semantic representations and semantic feature structure descriptions to elementary trees. Semantic computation is guided by the derivatio...
