| A Refined Approach | In developing an improved model, we need to better exploit the discourse parser’s output to provide more circumstantial evidence to support the system’s coherence decision. |
| Experiments | We must also be careful in using the automatic discourse parser . |
| Experiments | We note that the discourse parser of Lin et a1. |
| Experiments | Since the discourse parser utilizes paragraph boundaries but a permuted text does not have such boundaries, we ignore paragraph boundaries and treat the source text as if it has only one paragraph. |
| Introduction | To the best our knowledge, this is also the first study in which we show output from an automatic discourse parser helps in coherence modeling. |
| Related Work | This task, discourse parsing , has been a recent focus of study in the natural language processing (NLP) community, largely enabled by the availability of large-scale discourse annotated corpora (Wellner and Pustejovsky, 2007; Elwell and Baldridge, 2008; Lin et al., 2009; Pitler et al., 2009; Pitler and Nenkova, 2009; Lin et al., 2010; Wang et al., 2010). |
| Using Discourse Relations | To utilize discourse relations of a text, we first apply automatic discourse parsing on the input text. |
