RASTA (Rhetorical Structure Theory Analyzer), a system for automatic discourse analysis, reliably, identifies rhetorical relations present m written discourse by examining information available in syntactic and logical form analyses. Since there is a many-to-many relationship between rhetorical relations and elements of linguistic form, RASTA identifies relations by the convergence of a number ...

This paper briefly outlines observa.tions fi'om texts made with respect to rhetorical relations and communicative goals. Then it will be shown how these ol)servations have been encoded into knowledge resources which are part of an integrated architecture for the gelmration of multimedia output. Both communicative goals and rhetorical relations are virtual constructs surface signals hint at thei...

Knowledge about the rhetorical structure of a text is useful for automatic abstraction. We are interested in the automatic extraction of rhetorical units from the source text, units such as Problem Statement, Conclusions and Results. We want to use such extracts to generate high-compression abstracts of scientiic articles. In this paper, we present an extension of Kupiec, Pedersen and Chen's (1...

Rhetorical biset functors can be defined for any family of finite groups that is closed under subquotients up to isomorphism. The rhetorical p-biset functors almost coincide with the rational p-biset functors. We show that, over a field with characteristic zero, the rhetorical biset functors are semisimple and, furthermore, they admit a character theory involving primitive characters of automor...
