 In language generation, discourse structure relations often play a prescriptive role in determining what to say next. If content has already been selected, that content in conjunction with discourse structure can be used to constrain what gets said next. PDTB relations have been empirically determined through analysis of text and there has been an effort to limit the range of relations. One natural question is whether PDTB relations should serve the same role as RST in generating of text or whether there is a difference in how they could be applied.  Could the specific annotation of senses associated with relations be used to help determine content? There is an aspect of the PDTB which differs from earlier work on RST as it ties in closer to the syntactic structure of the text. Could the close coupling of discourse structure, syntactic structure and sense annotation offer an advantage over previous methods? One possibility would be to explore the role it could play in sentence planning, the problem of determining how to combine simple propositions to generate more complex sentences. In language generation, discourse structure relations often play a prescriptive role in determining what to say next.
