Fit it in but say it well

Reasoning about how much content to generate when space is limited presents an increasingly important challenge for generation systems, as the diversity of potential delivery channels continues to grow. The problem is multi-facetted: the generated text must fit into the allocated space, the space available must be well utilised, and the resulting text must convey its intended message, and be coherent, well structured and balanced. To address this problem, we use a discourse planning approach. Our system reasons about the discourse structure to decide how much content to realise. In this paper, we present two algorithms that perform this reasoning and analyse their effectiveness.
