A concept of derivation for LFG
Jürgen Wedekind · 1986
In this paper a version of LFG will be developed, which has only one level of representation and is equivalent to the modified version of [2], presented in [3]. The structures of this monostratal version are f-structures, augmented by additional information about the derived symbols and their linear order. For these structures it is possible to define an adequate concept of direct derivability by which the derivation process becomes more efficient, as the f-description solution algorithm is directly simulated during the derivation of these structures, instead of being postponed. Apart from this it follows from this reducability that LFG as a theory in its present form does not make use of the c-structure information that goes beyond the mere linear order of the derived symbols.
