We report results of experiments which build and re ne models of rhetorical- semantic relations such as Cause and Con- trast. We adopt the approach of Marcu and Echihabi (2002), using a small set of patterns to build relation models, and ex- tend their work by re ning the training and classi cation process using parame- ter optimization, topic segmentation and syntactic parsing. Using human-annotated and automatically-extracted test sets, we nd that each of these techniques results in improved relation classi cation accuracy.
