Discourse Structures for Text Generation
نویسنده
چکیده
A bst ract Text generation programs need to be designed around a theory of text organization. This paper introduces Rhetorical Structure Theory, a theory of text structure in which each region of text has a central nuclear part and a number of satellites related to it. A natural text is analyzed as an example, the mechanisms of the theory are identified, and their formalization is discussed. In a comparison, Rhetorical Structure Theory is found to be more comprehensive and more informative about text function than the text organization parts of previous text generation systems.

The Rhetorical Parsing, Summarization, and Generation of Natural Language Texts
This thesis is an inquiry into the nature of the high-level, rhetorical structure of unrestricted natural language texts, computational means to enable its derivation, and two applications (in automatic summarization and natural language generation) that follow from the ability to build such structures automatically. The thesis proposes a rst-order formalization of the high-level, rhetorical st...

I want to tell a story about computational approaches to discourse structure. Like all such stories, it takes some liberty with actual events and times, but I think stories put things into perspective, and make it easier to understand where we are and how we might progress. Part 1 of the story (Section 2) is the past. Here we see early computational work on discourse structure aiming to assign ...

متن کاملFocus Constraints on Language Generation
Computer generation of natural language requires the ability to make reasoned choices from a large number of possible things to say as well as from a large number of expressive possibilities. This paper examines in detail how one influence on a generated text, focus of attention, can be used to constrain the many possibilities that a generation system must consider. A computational treatment of...
متن کاملGenerating Discourse Structures for Written Text
This paper presents a system for automatically generating discourse structures from written text. The system is divided into two levels: sentence-level and text-level. The sentence-level discourse parser uses syntactic information and cue phrases to segment sentences into elementary discourse units and to generate discourse structures of sentences. At the text-level, constraints about textual a...
