Synchronous Vector TAG for Syntax and Semantics: Control Verbs, Relative Clauses, and Inverse Linking

Abstract

Recent work has used the synchronous tree-adjoining grammar (STAG) formalism to demonstrate that many of the cases in which syntactic and semantic derivations appeared to be divergent could be handled elegantly through synchronization. This research has provided syntax and semantics for diverse and complex lin- guistic phenomena. However, certain hard cases push the STAG formalism to its limits, requiring awkward analyses or leaving no clear solution at all. In this paper a new variant of STAG, synchronous vector TAG (SV-TAG), and demonstrate that it has the potential to handle hard cases such as control verbs, relative clauses, and in- verse linking, while maintaining the simplicity of previous STAG syntax-semantics analyses.
