1 Do online political discussions tend to aggregate diverse voices in cross-cutting debate and deliberation? Or do " audiences " for online discussion tend to fragment into ideological echo chambers? In the wilds of threaded discussion on the internet (as opposed to deliberative polls, moderated discussions, and other designed venues of deliberation), networks of political discourse emerge from...

This paper surveys work on applying the insights of lexicalized grammars to low-level discourse, to show the value of positing an autonomous grammar for low-level discourse in which words (or idiomatic phrases) are associated with discourse-level predicate–argument structures or modification structures that convey their syntactic-semantic meaning and scope. It starts by describing a lexicalized...

Cognitive Grammar presupposes an inherent and intimate relation between linguistic structures and discourse. Linguistic units are abstracted from usage events, retaining as part of their value any recurring facet of the interactive and discourse context. Linguistic structures thus incorporate discourse expectations and are interpretable as instructions to modify the current discourse state. The...

The paper shows how sentences containing scope ambiguities can be assigned syntactic and semantic structures by means of sloppy deterministic processing techniques only. The semantic framework is Discourse Representation Theory, and the sloppy deterministic parser is described in Nordgård (1993). Of primary concern for the article is the transition from syntactic structures to discourse represe...

The eeects of discourse on disambiguating (sub)expressions and the problem of computing those eeects are treated formally by imposing a labeling structure over discourse representation structures, leading to barebones forms of Segmented and Underspeciied Discourse Representation Theory.

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...

We describe a data-driven approach to building interpretable discourse structures for appointment scheduling dialogues. We represent discourse structures as headed trees and model them with probabilistic head-driven parsing techniques. We show that dialogue-based features regarding turn-taking and domain specific goals have a large positive impact on performance. Our best model achieves an f sc...

In constructing a distinctive polemic, postmodern architecture presented itself as a reaction to the modem movement, embodying both its negation and transcendence. In the ongoing debate over the definition of postmodernity as a cultural condition, the position of negation continues to come under severe criticism. This thesis attempts to understand constituents of the ideological discourse of po...
