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.
