Spatial Descriptions as Referring Expressions in the MapTask Domain.

Our approach 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 number
