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 assumption presents difficulties for the compositional interpretation of NP coordination structures, and proposes an analysis which is based on LTAG semantics with semantic unification, developed in Kallmeyer and Romero 2004.
