TITLE:	   A Computational Model for the Analysis of Arguments

ABSTRACT:

This research proposes a model for an argument understanding system--a 
natural language understanding system which processes arguments.  The
form of input considered is one-way communication in a conversational
setting, where the speaker tries to convince the hearer of a particular
point of view.  The main contributions are:  (i) a theory of expected
coherent structure which limits analysis to the reconstruction of
particular transmission forms (ii) a theory of linguistic clues which
assigns a functional interpretation to special words and phrases used 
by the speaker to indicate structure (iii) a theory of evidence relationships
which includes the demand for pragmatic analysis to accommodate beliefs
not currently held.  A system designed to incorporate these theories could
be used to analyze the structure of arguments--the necessary first step
for a hearer, before judging credibility and responding.
