RASTA (Rhetorical Structure Theory Analyzer), a discourse analysis component within the Microsoft English Grammar, efficiently computes representations of the structure of written discourse using information available in syntactic and logical form analyses. RASTA heuristically scores the rhetorical relations that it hypothesizes, using those scores to guide it in producing more plausible discou...

Text-level discourse parsing is notoriously difficult, as distinctions between discourse relations require subtle semantic judgments that are not easily captured using standard features. In this paper, we present a representation learning approach, in which we transform surface features into a latent space that facilitates RST discourse parsing. By combining the machinery of large-margin transi...

The CoNLL-2015 shared task focuses on shallow discourse parsing, which takes a piece of newswire text as input and returns the discourse relations in a PDTB style. In this paper, we describe our discourse parser that participated in the shared task. We use 9 components to construct the whole parser to identify discourse connectives, label arguments and classify the sense of Explicit or Non-Expl...

It is generally agreed that discourse has a recursive structure and that this structure aaects the semantic interpretation of discourse. Despite this consensus however, few proposals give a precise specii-cation of how the syntax of discourse relates to its semantics. In this paper, I use a variant of Feature-Based Tree Adjoining Grammars to construct discourse structure and its associated sema...

Existing discourse research only focuses on the monolingual languages and the inconsistency between languages limits the power of the discourse theory in multilingual applications such as machine translation. To address this issue, we design and build a bilingual discource corpus in which we are currently defining and annotating the bilingual elementary discourse units (BEDUs). The BEDUs are th...

this study tries to show that how viewpoint functions in discourse. as it will be clarified, it is highly related to the intention of the speaker/writer, and as a result, the orientation (s)he adopts in the discourse. deictic markers function as discourse markers to fix and anchor time, place, agent, and other discursive elements. in this way, the viewpoint adopted by the enunciator/utterer is ...

3. Four selected types of discursive formations 3.1 The discourse of the master 3.2 The discourse of knowledge 3.3 The discourse of lived relationships 3.4 The discourse of the unconscious 4. Some ethical bearings of the interactive-constructivist theory of discourse References 1 Interactive constructivism is a socially and culturally orientated form of constructivism, articulated within the ph...

Recent work investigates the ordering constraints discourse relations impose on texts. Wolf and Gibson (2003) generated GraphBank, a discourse-annotated corpus without a prior constraint to tree-structured annotations, showing that naive annotators generate representations containing multiple-parented nodes and relations with crossing arguments. Webber et al. (2003) hypothesize that discourse m...

Topic Areas or Theme ID: discourse analysis, discourse segmentation, discourse plans Word Count: 3196 words (excluding gures) Under consideration for other conferences (specify)? No. Abstract We propose a promising research problem, the machine veriication of textbook proofs. It shows that textbook proofs are a suuciently complex and highly struc-tured form of discourse, embedded in a well-deen...

An important aspect of discourse understanding and generation involves the recognition and processing of discourse relations. These are conveyed by discourse connectives, i.e., lexical items like because and as a result or implicit connectives expressing an inferred discourse relation. The Penn Discourse TreeBank (PDTB) provides annotations of the argument structure, attribution and semantics o...
