The f-structure functional annotation algorithm assumes that each one of the syntactic units in the KTC4 representation corresponds to one sub-f-structure and that they combine with each other according to the unlabelled dependency relation provided in the KTC4 representation, to constitute one f-structure for the sentence as a whole.
what is projected from one node in a phrase-structure tree of a configurational language, such as English, is projected from one syntactic unit of Japanese.
