Title Compilation Of HPSG To TAG
Venue Annual Meeting of the Association of Computational Linguistics
Session Main Conference
Year 1995

We present an implemented compilation algorithm that translates HPSG into lex- icalized feature-based TAG, relating con- cepts of the two theories. While HPSG has a more elaborated principle-based theory of possible phrase structures, TAG pro- vides the means to represent lexicalized structures more explicitly. Our objectives are met by giving clear definitions that de- termine the projection of structures from the lexicon, and identify "maximal" pro- jections, auxiliary trees and foot nodes.
