Dr. Robin Cohen of the University of Toronto will speak on ``A Computational Model for the Analysis of Argu- ments''. TIME: 3:30 PM ROOM: MC 5158 ABSTRACT This research proposes a model for an argument under- standing system - a natural language understanding sys- tem which processes arguments. The form of input con- sidered in 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 particu- lar transmission forms (ii) a theory of linguistic clues which assigns a functional interpretation to spe- cial words and phrases used by the speaker to indicate structure (iii) a theory of evidence relationships which includes the demand for pragmatic analysis to ac- comodate 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 respond- ing. March 12, 1984
