This work proposes a complete probabilistic discriminative framework for performing sentence-level discourse analysis that outperforms the state-of-the-art, often by a wide margin.

Abstract

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. 1
