Sentences form coherent relations in a discourse without discourse connectives more frequently than with connectives. Senses of these implicit discourse relations that hold between a sentence pair, however, are challenging to infer. Here, we employ Brown cluster pairs to represent discourse relation and incorporate coreference patterns to identify senses of implicit discourse relations in natur...

Previous experimental studies on concessive connectives have only looked at their local facilitating or predictive effect on discourse relation comprehension and have often viewed them as a class of discourse markers with similar effects. We look into the effect of two connectives, but and although, for inferring contrastive vs. concessive discourse relations to complement previous experimental...

Studies of discourse relations have not, in the past, attempted to characterize what serves as evidence for them, beyond lists of frozen expressions, or markers, drawn from a few well-defined syntactic classes. In this paper, we describe how the lexicalized discourse relation annotations of the Penn Discourse Treebank (PDTB) led to the discovery of a wide range of additional expressions, annota...

The paper presents machine translation experiments from English to Czech with a large amount of manually annotated discourse connectives. The gold-standard discourse relation annotation leads to better translation performance in ranges of 4–60% for some ambiguous English connectives and helps to find correct syntactical constructs in Czech for less ambiguous connectives. Automatic scoring confi...

This chapter examines the way online language users enhance social interaction and group collaboration through the computer mediated communication (CMC) channel. For this, discourse analysis based on the linguistic politeness theoretical framework is applied to the transcripts of a real time online chat. Analysis of the data shows that online participants employ a variety of creative devices to...

Over the years, research on women in the fisheries moved from a framework of political economy to a framework of political ecology. This meant that analyses shifted away from labour, production relations and surplus value extraction typically grounded in Marxian modes of analysis, in favour of those focused on environmental sustainability, livelihood sustainability and a discourse on poverty. D...
