We propose a complete probabilistic discrim- inative framework for performing sentence- level discourse analysis. Our framework com- prises a discourse segmenter, based on a bi- nary classifier, and a discourse parser, which applies an optimal CKY-like parsing algo- rithm to probabilities inferred from a Dynamic Conditional Random Field. We show on two corpora that our approach outperforms the state-of-the-art, often by a wide margin.
