Computationally modeling the evolution of science by tracking how scientific topics rise and fall over time has important implications for research funding and public policy. However, little is known about the mechanisms underlying topic growth and decline. We investigate the role of rhetorical framing: whether the rhetorical role or function that authors ascribe to topics (as methods, as goals...

Abstract in every research paper has always been functioning as an attention-grabber which can encourage readers to keep reading the research or to dissuade it. Although abstracts are believed to play an important role in distributing the research findings, few studies have been done to evaluate the rhetorical organization of thesis abstracts, especially in the field of Teaching English as a Fo...

In this paper, we propose a novel Rhetorical Structure Index (RSI) to measure the structural importance of a word or a phrase. Unlike TF-IDF and other content-driven measurements, RSI identifies words or phrases that are structural cues in an unstructured document. We show structurally motivated features with high RSI values are more useful than content-driven features for applications such as ...

RASTA (Rhetorical Structure Theory Analyzer), a system for automatic discourse analysis, reliably, identifies rhetorical relations present m written discourse by examining information available in syntactic and logical form analyses. Since there is a many-to-many relationship between rhetorical relations and elements of linguistic form, RASTA identifies relations by the convergence of a number ...

We present our recent work on query-focused summarization, focusing on our efforts in building and applying models of rhetorical-semantic relations (RSRs) such as contrast and causality. We overview ongoing work in extracting and evaluating RSR models. We describe our system for query-focused summarization, focusing on an enhanced, feature-based framework. We present results of experiments to m...
