Feature-Based TAG in place of multi-component adjunction: Computational Implications

TL;DR

This paper demonstrates that feature-based Tree Adjoining Grammar (TAG) can analyze complex constructions in English effectively, allowing existing parsers to handle them without multi-component adjunction, thus simplifying computational implementation.

Contribution

It introduces a feature-based TAG approach that replaces multi-component adjunction, enabling efficient parsing with existing unification-based TAG parsers.

Findings

Feature-based TAG can analyze constructions previously requiring multi-component adjunction.

Existing TAG parsers can parse these constructions without modifications.

The approach maintains linguistic coverage for English.

Abstract

Using feature-based Tree Adjoining Grammar (TAG), this paper presents linguistically motivated analyses of constructions claimed to require multi-component adjunction. These feature-based TAG analyses permit parsing of these constructions using an existing unification-based Earley-style TAG parser, thus obviating the need for a multi-component TAG parser without sacrificing linguistic coverage for English.
