Flexible Composition and Delayed Tree-Locality.
David Chiang, Tatjana Scheffler · 2008
Flexible composition is an extension of TAG that has been used in a variety of TAG-analyses. In this paper, we present a dedicated study of the formal and linguistic properties of TAGs with flexible composition (TAG-FC). We start by presenting a survey of existing applications of flexible composition. In the main part of the paper, we discuss a formal definition of TAG-FCs and give a proof of equivalence of TAG-FC to tree-local MCTAG, via a formalism called delayed tree-local MCTAG. We then proceed to argue that delayed treelocality is more intuitive for the analysis of many cases where flexible composition has been employed. 1
