In this paper we study the utility of dis- course structure for spoken dialogue per- formance modeling. We experiment with various ways of exploiting the discourse structure: in isolation, as context infor- mation for other factors (correctness and certainty) and through trajectories in the discourse structure hierarchy. Our corre- lation and PARADISE results show that, while the discourse structure is not useful in isolation, using the discourse structure as context information for other factors or via trajectories produces highly predic- tive parameters for performance analysis.
