We describe a method and its implementation for self-monitoring during
natural language generation. In situations of communication where the
generation of ambiguous utterances should be avoided our method is
able to compute an un-ambiguous utterance for a given semantic input.
The proposed method is based on a very strict integration of parsing
and generation. During the monitored generation step, a previously
generated (possibly) ambiguous utterance is parsed and the obtained
alternative derivation trees are used as a `guide' for re-generating
the utterance. To achieve such an integrated approach the underlying
grammar must be reversible.
