EXTENDIBLE STRUCTURAL TRANSFER: A CASE FOR GERMAN TO TURKISH TRANSLATION This study presents the design of a converter from HPSG feature structures to a Common Case Frame representation. The purpose of this work is to extend the scope of a machine translation system from bilinguality to multilinguality. There is a need for an interface between the analyzer and the transfer module in a transfer based MT system. This experiment aims to find out the extendibility of the present interface.
