The rhetorical classification of sentences in biomedical texts is an important task in the recognition of the components of a scientific argument. Generating supervised machine learned models to do this recognition requires corpora annotated for the rhetorical categories Introduction (or Background), Method, Result, Discussion (or Conclusion). Currently, a few, small annotated corpora exist. We...

This paper presents a corpus study of parenthetical constructions in two different corpora: the Penn Discourse Treebank (PDTB, (PDTBGroup, 2008)) and the RST Discourse Treebank (Carlson et al., 2001). The motivation for the study is to gain a better understanding of the rhetorical properties of parentheticals in order to enable a natural language generation system to produce parentheticals as p...

Summarization involves finding the most important information in a text in order to convey the meaning of the document. In this paper, I present a method for using topic information to influence which content is selected for a summary. Texts are divided into topics using rhetorical information that creates a partition of a text into a sequence of non-overlapping topics. To investigate the effec...

In this paper, we describe a content planning mechanism which takes into consideration a user's possible inferences in order to generate the most concise discourse that achieves a given communicative goal. The consideration of a user's inferences results in the addition of information that addresses erroneous inferences , and the omission of easily inferred information. Given a communicative go...

Linguistic annotation provides additional information asserted with a particular purpose in a document or other piece of information. It is widely used in various fields, from computing and bioinformatics, through imaging, to law and linguistics. There is also a clear distinction between what is communicated through the written/spoken natural language and how this is passed on. We are studying ...

This paper investigates whether the model of local rhetorical coherence suggested in Knott et al. (2001) can boost the performance of the Centering-based metrics of entity coherence employed by Karamanis et al. (2004) for the task of information ordering. Our results indicate that (a) the simplest metric continues to perform better than its competitors even when local rhetorical coherence is ta...

While quite a few linguistic corpora with syntactic annotations are available today, resources are scarce on the level of discourse annotation. A flexible, extendible annotation format speeds up development. We therefore propose an XML format for annotating rhetorical structure trees. In human and automatic analysis, rhetorical structure is often difficult and assigned incrementally. Thus, the ...

due to the existence of different criticism criteria in different eras, the critics have applied different and sometimes opposing methods in literary criticism. the present article studies the popular methods of literary criticism and the evolution of one special method which has been called preference in some era and comparison in some other era.

This comparative study aimed at finding out the types of grammatical shifts which have occurred in two English translations of the Quranic rhetorical questions, and the impact of such shifts on the said rhetorical questions. For these purposes, the study firstly analyzed the Arabic and English texts syntactically using the x-bar theory for Haegeman (2006) and then classified the grammatical shi...

Abstract Although flourishing research has been devoted to research on article abstracts, more studies are needed to unpack the relationship between rhetorical moves and their associated linguistic and rhetorical features (e.g., metadiscourse). To underpin this relationship, the current study analyzed a total of 60 research article abstracts written in English by two cultural groups in three di...
