Previous work by Lin et al. (2011) demonstrated the effectiveness of using discourse relations for evaluating text coherence. However, their work was based on discourse relations annotated in accordance with the Penn Discourse Treebank (PDTB) (Prasad et al., 2008), which encodes only very shallow discourse structures; therefore, they cannot capture long-distance discourse dependencies. In this ...

We address the problem of building a flexible discourse model that enables creation of relatively complex discourse structures by using a semantic framework and semantic descriptions of media items. With such model we intend to support different approaches to hypermedia presentation authoring. We give a short overview of existing hypermedia presentation generation systems and discuss what type ...

the efficacy of genre-based approach to teaching writing has been regarded as an influential practice in l2 writing pedagogy (hyland, 2007). however, there is still gap between actual structures found in reading materials recommended as textbooks and discourse patterns recommended for l2 writing in efl contexts, the gap which would highlight the problems of genre and rhetorical patterns for tea...

This paper sets to investigate the responses of the Greek and Irish social actors (trade unions, employers’ organizations, public agencies) to the youth unemployment which has severely risen in both countries after the outbreak of the economic crisis (OECD, 2009). The rationale behind the comparative perspective stems from our intention to investigate how the institutional structures and the in...

The term discourse structure is used to denote any structure of a text above that of the sentence. Trees have often been posited as a good abstraction when discourse is taken to have a hierarchical structure (Mann and Thompson 1987; Webber et al. 2003; Marcu 2000; Egg and Redeker 2008). Nevertheless, periodically researchers have commented on the need to depart from the strict singleparent hier...

In this paper we propose a method of reducing the search space of a discourse parsing process, while keeping unaffected its capacity to generate cohesive and coherent tree structures. The parsing method uses Veins Theory (VT), by developing incrementally a forest of parallel discourse trees, evaluating them on cohesion and coherence criteria and keeping only the most promising structures to go ...

Discourse parsing aims to identify the relationship between different discourse units, where most previous works focus on recovering the constituency structure among discourse units with carefully designed features. In this paper, we propose to exploit Long Short Term Memory (LSTM) to properly represent discourse units, while using as few feature engineering as possible. Our transition based pa...
