This paper describes two algorithms which construct two differ- ent types of generators for lexical functional grammars (LFGs). The first type generates sentences from functional structures and the sec- ond from semantic structures. The latter works on the basis of ex- tended LFGs, which contain a mapping from f-structures into seman- tic structures. Both algorithms can be used on all grammars within the respective class of LFG-grammars. Thus sentences can be gener- ated from input structures by means of LFG-grammars and the same grammar formalism, although not necessarily the same grammar, can be used for both analysis and synthesis.
