Mann usc lnformation Sciences Institute 4676 Admiralty Way Marina del Rey CA 90292-6695 Abstract 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. 1. The Text Organization Problem Text generation is already established as a research area within computational linguistics. Although so far there have been only a few research computer programs that can generate text in a technically interesting way text generation is recognized as having problems and accomplishments that are distinct from those of the rest of computational linguistics. Text generation involves creation of multisentential text without any direct use of people s linguistic skills it is not computer-aided text creation. Text planning is a major activity within text generation one that strongly influences the effectiveness of generated text. Among the things that have been taken to be part of text planning this paper focuses on just one text organization. People commonly recognize that well-written text is organized and that it succeeds partly by exhibiting its organization to the reader. Computer generated text must be organized.
