                         "The Rhetorical Parsing,
         Summarization, and Generation of Natural Language Texts"


        Researchers of natural language have repeatedly acknowledged that
coherent texts are not just simple sequences of sentences.  Rather, they
are complex artifacts whose semantic units are connected by rhetorical,
logical, argumentative, and cohesive relations.  I present results in
theoretical, empirical, and applied computational linguistics that aim at
uncovering the formal properties and the constraints that characterize the
abstract structure of well-formed texts, and at producing algorithms for
the automatic derivation of these structures.  I give a first-order
formalization of the abstract structure of unrestricted texts and discuss
applications of this formalization in automatic summarization and natural
language generation.
