6. Underspecified discourse representation
This paper proposes an approach to discourse structure that builds on syntactic structure to derive that part of discourse structure that can be captured without taking recourse to deep semantic or conceptual knowledge. This contribution is typically only partial; we intend to capture this partiality in terms of <i>underspecified constraints </i>that describe (but do not enumerate) the structures a given discourse might have. This allows a rather straightforward interface from syntax to discourse and yields a clean interface to modules of discourse resolution.
