This paper considers the problem of auto- matic assessment of local coherence. We present a novel entity-based representa- tion of discourse which is inspired by Cen- tering Theory and can be computed au- tomatically from raw text. We view co- herence assessment as a ranking learning problem and show that the proposed dis- course representation supports the effec- tive learning of a ranking function. Our experiments demonstrate that the induced model achieves significantly higher ac- curacy than a state-of-the-art coherence model.
