In this paper we present an ambiguity preserv- ing translation approach which transfers am- biguous LFG f-structure representations. It is based on packed f-structure representations which are the result of potentially ambiguous utterances. If the ambiguities between source and target language can be preserved, no un- packing during transfer is necessary and the generator may produce utterances which max- imally cover the underlying ambiguities. We convert the packed f-structure descriptions into a flat set of prolog terms which consist of pred- icates, their predicate argument structure and additional attribute-value information. Ambi- guity is expressed via local disjunctions. The flat representations facilitate the application of a Shake-and-Bake like transfer approach extended to deal ...
