Feature Unification in TAG Derivation Trees
Sylvain Schmitz, Joseph Le Roux · arXiv (Cornell University) · 2008
The derivation trees of a tree adjoining grammar provide a first insight into the sentence semantics, and are thus prime targets for generation systems. We define a formalism, feature-based regular tree grammars, and a translation from feature based tree adjoining grammars into this new formalism. The translation preserves the derivation structures of the original grammar, and accounts for feature unification.
