Using Cue Phrases To Determine Rhetorical Relations
نویسنده
چکیده
'Relation based' approaches to discourse analysis and text generation suffer from a common problem: there is considerable disagreement between researchers over the set of relations which is proposed. Few researchers use identical sets of relations, and many use relations not found in any other sets. This proliferation of relations has been pointed out before (eg Hovy [1]), and several methods for justifying a standard set of relations have been proposed: this paper reviews some of these, and presents a new method of justification which overcomes some awkward problems.

Using Cohesive Devices to Recognize Rhetorical Relations in Text
This paper investigates factors that can be used in discourse analysis, specifically, cohesive devices. The paper shows that cohesive devices such as cue phrases can provide information about the linkages inside a text. We propose three types of cue phrases (the ordinary cue phrases, noun-phrase cues, and verb-phrase cues). An algorithm to compute rhetorical relations between two elementary dis...
متن کاملExploiting Linguistic Cues to Classify Rhetorical Relations
We propose a method for automatically identifying rhetorical relations. We use supervised machine learning but exploit cue phrases to automatically extract and label training data. Our models draw on a variety of linguistic cues to distinguish between the relations. We show that these feature-rich models outperform the previously suggested bigram models by more than 20%, at least for small trai...
