We present a discourse-level Tree Adjoin- ing Grammar which tightly integrates syn- tax and discourse levels, including a repre- sentation for discourse entities. We show that this technique makes it possible to extend an optimisation algorithm used in natural language generation (polarity fil- tering) to the discourse level. We imple- mented the grammar in a surface realizer and show that this technique can be used to reduce the search space by filtering out referentially incoherent solutions.
