TAILIEUCHUNG - Báo cáo khoa học: " MISREPRESENTATION AND CONTEXT IN DIALOGUE"

In this paper we discuss a mechanism for modifying context in a tutorial dialogue. The context mechanism imposes a pedagogically motivated misrepresentation (PMM) on a dialogue to achieve instructional goals. In the paper, we outline several types of PMMs and detail a particular PMM in a sample dialogue situation. While the notion of PMMs are specifically oriented towards tutorial dialogue, m i s r e p r e s e n t a t i o n has interesting implications for context in dialogue situations generally, and also suggests that Grice's maxim of quality needs to be modified | WOULD I LIE TO YOU MODELLING MISREPRESENTATION AND CONTEXT IN DIALOGUE Carl Gutwin Alberta Research Council1 2 6815 8th Street N E Calgary Alberta T2E 7H7 Canada Internet gutwin@ Gordon McCalla ARIES Laboratory University of Saskatchewan Saskatoon Saskatchewan S7N owo Canada ABSTRACT In this paper we discuss a mechanism for modifying context in a tutorial dialogue.

INTRODUCTION Most of the time truth is a wonderful thing. However this research studies situations where not saying what you believe to be the truth can be the best course of action. Intentional misrepresentation of a speaker s knowledge appears to be a common and highly pragmatic process used in many different kinds of dialogue especially tutorial dialogue. We use imperfect or incomplete representations in response to consttaints and demands imposed by the situation for example many models of the real world are extremely complex and misrepresentations are often used as useful comprehensible approximations of complicated systems. People use idealized Newtonian mechanics the wave or particle theory of light and rules of default reasoning stating that birds fly penguins are birds and penguins don t fly. Some systems which cannot be simplified are purposefully ignored for example higher order 1 This research was completed while c. Gutwin was a graduate student at the University of Saskatchewan.
