In the late 1990s, AI witnessed an increasing use of the term
'argumentation' within its bounds: in natural language processing, in
user interface design, in logic programming and nonmonotonic reasoning,
in Al's interface with the legal community, and in the newly emerging
field of multi-agent systems. It seemed to me that many of these uses of
argumentation were inspired by (of- ten inspired) guesswork, and that a
great majority of the AI community were unaware that there was a
maturing, rich field of research in Argumentation Theory (and Critical
Thinking and Informal Logic) that had been steadily re- building a
scholarly approach to the area over the previous twenty years or so.
Argumentation Theory, on its side; was developing theories and
approaches that many in the field felt could have a role more widely in
research and soci- ety, but were for the most part unaware that AI was
one of the best candidates for such application.
