among discourse theories, laclau and mouffe,s theory has great importance, because in this theory we can see that there is a useful relationship between discourse that has originated from linguistics and culture politics and society. laclau and mouffe have been able to formulate a theory that is profitable for explaining political phenomena . how ever this theory is not a homogeneous theory, be...

The readers' ability to integrate current information with given information has been considered as an important component of reading comprehension process. One aspect of this integration process involves anaphoric resolution. The purpose of this study is to investigate the process of anaphoric resolution, focusing on inferential rigidity of different types of anaphoric ties. Ninety EFL learner...

This paper presents a brief description of Explanation-Based Learning (EBL), and argues that it is an approach to machine learning with signi cant potential for use in discourse processing. More speci cally, EBL can be used by systems that model discourse generation as goaldriven behavior, and that model discourse interpretation as recognizing the speaker's discourse goals. As evidence, we desc...

How to represent knowledge is one of the key questions in the construction of expert systems. Its solution depends on a number of factors, the most important of which are how knowledge is to be acquired and how it is to be used. Since we are interested in the use of natural language for communication with computers, we require from a formalism suggested for knowledge representation that it be s...

In order to improve Large Vocabulary Continuous Speech Recognition (LVCSR) systems, it is essential to discover exactly how our current systems are underperforming. The major intellectual tool for solving this problem is error analysis: careful investigation of just which factors are contributing to errors in the recognizers. This paper presents our observations of the effects that discourse (i...

Asbtract This paper elaborates on an FPA approach of EFP and on the added value of certain social constructivist approaches relying on discourse analysis. While discourse analysis has sometimes been presented as competing with traditional approaches of FPA, both can also be seen as complementary, we will draw on a revised FPA framework (White, 2001) and highlight how a discourse analysis approa...

Discourse relation classification is an important component for automatic discourse parsing and natural language understanding. The performance bottleneck of a discourse parser comes from implicit discourse relations, whose discourse connectives are not overtly present. Explicit discourse connectives can potentially be exploited to collect more training data to collect more data and boost the p...

We present an implementation of a discourse parsing system for a lexicalized TreeAjoining Grammar for discourse, specifying the integration of sentence and discourse level processing. Our system is based on the assumption that the compositional aspects of semantics at the discourse-level parallel those at the sentence-level. This coupling is achieved by factoring away inferential semantics and ...
