We used functional magnetic resonance imaging (fMRI) to identify brain regions involved in the process of mapping coherent discourse onto a developing mental representation. We manipulated discourse coherence by presenting sentences with definite articles (which lead to more coherent discourse) or indefinite articles (which lead to less coherent discourse). Comprehending connected discourse, co...

Spontaneous speech poses problems for automatic systems. While many investigators are making progress in recognition and dialogue processing, spontaneous speech also raises interesting problems for a deeper level of discourse modeling. Here, the discourse segmentation (Grosz and Sidner, 1986) and the centering frameworks (Grosz, Joshi and Weinstein, 1995) are used to track the evolution of loca...

Over the years, the usage of discourse relations has been proven to enhance many applications such as text summarization, question answering and natural language generation. This paper proposes an approach that expands the benefit of discourse relations for natural language processing from a different aspect. We exploit the discourse relations existing between sentences to generate clusters of ...

This demo presents the TextCoop platform and the Dislog language, based on logic programming, which have primarily been designed for discourse processing. The linguistic architecture and the basics of discourse analysis in TextCoop are introduced. Application demos include: argument mining in opinon texts, dialog analysis, and procedural and requirement texts analysis. Via prototypes in the ind...

The paper shows how sentences containing scope ambiguities can be assigned syntactic and semantic structures by means of sloppy deterministic processing techniques only. The semantic framework is Discourse Representation Theory, and the sloppy deterministic parser is described in Nordgård (1993). Of primary concern for the article is the transition from syntactic structures to discourse represe...

This demo presents Graphia, an information extraction pipeline targeting an RDF representation of unstructured data in the form of structured discourse graphs (SDGs). It combines natural language processing and information extraction techniques with the use of linked open data resources and semantic web technologies to enable discourse representation as a set of contextualized relationships bet...

Interactive generative musical performance provides a suitable model for communication because, like natural linguistic discourse, it involves an exchange of ideas that is unpredictable, collaborative, and emergent. Here we show that interactive improvisation between two musicians is characterized by activation of perisylvian language areas linked to processing of syntactic elements in music, i...

It is well-known that interpretation of a text requires understanding of its rhetorical relation hierarchy since discourse units rarely exist in isolation. Such discourse structure is fundamental to document-level applications, such as text understanding, summarization, knowledge extraction and question-answering. In comparison with English, there are only a few studies on Chinese discourse ana...
