Since the pioneering work of Zadeh, fuzzy set theory has been applied to a myriad of areas. Song and Chissom introduced the concept of fuzzy time series and applied some methods to the enrollments of the University of Alabama. In recent years, a number of techniques have been proposed for forecasting based on fuzzy set theory methods. These methods have either used enrollment numbers or differe...

New methods from meta-programming in logic makes it possible automatically to extract grammar rules and other formal descriptions from a given text which characterize its inherent context and discourse. As context and discourse often vary within a text it is also suggested that different grammars be applied to different portions of the text and similarly for other relevant, formal descriptions.

in this paper attempts have been made to study the discourses dominating political islam to answer these questions: how can one categorize these diverse political islam discourses? what are the similarities and differences among these discourses in general, and with the islamic revolution discourse in particular? the research methodology employed for this study is historical-comparative and the...

This study examines the collective use of the electronic information and communication channels and their impact on citizen participation for public discourse. Using both quantitative and qualitative research methods, we investigate public communication channels available for government service provision in a large metropolis in China. Specifically, four electronic communication channels are an...

Human annotation of discourse corpora typically results in segmentation hierarchies that vary in their degree of agreement. This paper presents several techniques for unifying multiple discourse annotations into a single hierarchy, deemed a “gold standard” — the segmentation that best captures the underlying linguistic structure of the discourse. It proposes and analyzes methods that consider t...

This paper addresses the problem of segmenting German texts into minimal discourse units, as they are needed, for example, in RST-based discourse parsing. We discuss relevant variants of the problem, introduce the design of our annotation guidelines, and provide the results of an extensive interannotator agreement study of the corpus. Afterwards, we report on our experiments with three automati...

The Chinese comma signals the boundary of discourse units and also anchors discourse relations between adjacent text spans. In this work, we propose a discourse structureoriented classification of the comma that can be automatically extracted from the Chinese Treebank based on syntactic patterns. We then experimented with two supervised learning methods that automatically disambiguate the Chine...

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...
