We discuss work-in-progress on a hybrid ap- proach to the generation of spatial descriptions, using the maps of the Map Task dialogue cor- pus as domain models. We treat spatial de- scriptions as referring expressions that distin- guish particular points on the maps from all other points (potential ‘distractors’). Our ap- proach is based on rule-based overgeneration of spatial descriptions combined with ranking which currently is based on explicit goodness criteria but will ultimately be corpus-based. Ranking for content determination tasks such as referring expression generation raises a num- ber of deep and vexing questions about the role of corpora in NLG, the kind of knowledge they can provide and how it is used.
