TLDR
It is shown that an account for coordination can be constructed using the derivation structures in a lexicalized Tree Adjoining Grammar (LTAG) and the construction of a practical parser for LTAGs that can handle coordination including cases of non-constituent coordination is discussed.Abstract:
In this paper we show that an account for coordination can be constructed using the derivation structures in a lexicalized Tree Adjoining Grammar (LTAG). We present a notion of derivation in LTAGs that preserves the notion of fixed constituency in the LTAG lexicon while providing the flexibility needed for coordination phenomena. We also discuss the construction of a practical parser for LTAGs that can handle coordination including cases of non-constituent coordination.read more

Processing coordinated structures : Incrementality and connectedness
Patrick Sturt,Vincenzo Lombardo +1 more
TL;DR: It is argued that this result is incompatible with models of human parsing that employ only bottom-up parsing procedures, even when flexible constituency is employed, and models need to incorporate a mechanism similar to the adjoining operation in Tree-Adjoining Grammar.

TL;DR: This paper presents a system that automatically extracts lexicalized grammars from annotated corpora, and reports experimental results on two of those tasks and compares the approaches with related work.
Towards efficient statistical parsing using lexicalized grammatical information

TL;DR: This thesis develops supertagging models which achieve a significant improvement in accuracy over previous models, and investigates methods for improving the accuracy of supertagting in order to enhance its viability for full parsing.
STRUCTURE FOR COORDINATION Part I
TL;DR: In this article, the authors propose an inventaire des donnees representatives pertinentes permettant de determiner la structure de la coordination, and present analyses effectuees sur la coordination which ont particularite de ne pas traiter les conjonctions comme des tetes de syntagmes conjonctifs.

Partial proof trees as building blocks for a categorial grammar
Aravind K. Joshi,Seth Kulick +1 more
TL;DR: PPTS can be viewed as a categorial system incorporating some of the key insights of lexicalized tree adjoining grammar, namely the notion of an extended domain of locality and the consequent factoring of recursion from the domain of dependencies.

TL;DR: A representation of prepositional complements that is based on extended elementary trees, and how to deal with semantic non compositionality in verb-particle combinations, light verb constructions and idioms, without losing the internal syntactic composition of these structures are presented.

Gapping as constituent coordination
TL;DR: A number of coordinate constructions in natural languages conjoin sequences which do not appear to correspond to syntactic constituents in the traditional sense, and one striking instance of the phenomenon is afforded by the "gapping" construction of English.

An earley-type parsing algorithm for tree adjoining grammars
Yves Schabes,Aravjnd K. Joshi +1 more
TL;DR: An Earley-type parser for Tree Adjoining Grammars (TAGs) is described and with the use of substitution in TAGs the system is able to parse directly CFGs and TAGs and also allows the essential aspects of PATR-II.

Fixed and flexible phrase structure: coordination in tree adjoining grammars
Aravind K. Joshi,Yves Schabes +1 more
TL;DR: Phrase-structure grammars assign a unique phrase structure (constituency) to an unambiguous sentence, so that for example, John likes apples will be bracketed as follows.
